Here, then, in his own words, we have his method of deriving his proportions in transverse and vertical lines. Right or wrong, he concluded that these are correct for an entrance to his principal building.
Now out of this space, as a master of design he sets about, first, to secure to his major purpose its requisite share, without omitting to provide in a most economical manner for his minor demands. The upper two-thirds with its vaulted dome he devotes to his library, the lower one-third he utilizes in two floors, each containing two elliptical rooms with ample passage-and entrance-ways. For the use of his builders he gives transverse and vertical sections of the rotunda, just as he did for the portico. Hence, we must conclude that Jefferson possessed ability as a designer. (See Plates XV, XVI, XVII.)
The second requisite of an architect is his ability to construct. What did Jefferson know of the properties of materials, of the methods of combining them? What practical experience had he? Did he conform to the laws of scientific theory? Did he correctly estimate the cost of material and labor?
All these questions can be answered in the affirmative by examination of the same building. The roof of this building was a sufficient test of his practical ability in construction. This is the manner in which he accomplished his task. He first drew the plan of the roof giving the plates and ribs; the primary ribs extending from plate to crown, the secondary, three-quarters the way from plate to crown heading in on a secondary crown, the third running one-half way, and the fourth set running one-quarter way. Here are his own drawings and specifications. He says:
The thickness of the wall at top, to wit, at the spring of the vault of the roof is 22. in. On the top of the wall lay a curbed plate, in Delorm's manner, consisting of 4 thicknesses of 3.in. each, 22. in wide pieces 12 ft. long, breaking joints every 3 ft. bolted through with bolts of iron, having a nut and screw at their ends. On this curbed plate the ribs of the roof are to rest. The ribs are to be 4 in. thicknesses of one inch plank in pieces 4 ft. long, breaking joints at every foot. They are to be 18 in. wide, which leaves 4 in. of the plate for the attic upright to rest on. The ribs are to be keyed together by cross boards at proper intervals for the ribs to head in as they shorten. The curb of the sky light to be made also in Delorm's way but vertically. (See Plate XVII.)
Here is found illustrated a knowledge and a practical application of his ability in construction: a peculiar roof problem, which up to that time had not been solved with similar materials in America. His knowledge of the properties of materials was gained by a long life of very intelligent observation and very practical experience, to which he added scientific experiment. He exposed chestnut and hard pine to the weather in horizontal, vertical, and inclined positions for many years in order to measure their comparative durability. He personally examined brick construction in Lynchburg, Bedford, and elsewhere, and contrasted it with that of his own county, some of which he called barbarous. He directed that his brick walls should be laid throughout with alternate header and stretcher, not more than two bats to be used with every twelve brick, and that the joints should be solidly and evenly jointed throughout (not only on the surface). That mortar must be made of one third sand and two thirds lime.
His training in the management of mechanics, of laborers, and in the manufacture of building materials fitted him to calculate successfully the cost of construction. Further he had at hand Latrobe's estimate of the cost of Philadelphia building. On the back of each plan he enumerates the number of brick in each part of the building designed, even to the number in each column. From the number of brick he arrives at the total cost of construction, as is seen in the following example:
He says in Philadelphia they calculate roughly that: (1) The cost of brick walls as equal to the cost of carpenters' work. (2) The cost of carpenters' materials and ironmongery as equal to the cost of brick walls. He points out that this is more expensive than in Virginia at that time. These calculations are copied from specifications written by his own hand. There can be no question, then, as to his being qualified to estimate the cost.
There remains the third test to be applied before conclusion can be reached upon his architectural ability. It has been shown that he understood and appreciated the art of design and that he possessed the ability to construct. What ability did he have to decorate? What were his artistic powers?
If it was assumed that the University group was his creation, no further answer would be required they stand as an incontestable proof of some one's appreciative and highly developed artistic power. Such reverence for tradition, and such complete allegiance to the canons of good taste he has manifested in the detail of his ornament for the various units of his group and the various architectural members of his units, that no critic has yet pointed out a discordant note in the harmony of his theme. Always a motif, but never so often occurring as to appear monotonous nor so infrequent as to lose the air of continuity.
While he continuously had by him Palladio with his best types, he is never afraid to depart from the laws that authority works out; yet, when he has once departed, the end justifies the means. An example of one of his departures is preserved in his own words. What he says in his specifications for attic pilasters in his Theatre of Marcellus is highly interesting; he says:
I have never seen an attic pilaster, with the measures of its parts minutely expressed except that of the Temple of Nerva Trajan. That temple is so overloaded with ornament, and its pilaster frittered away so minutely in its mouldings as to lose all effect. I have simplified these mouldings to suit our plainer style, still, however, retaining nearly their general outlines and proportions. (See Plate XVIII.)
This is not the voice of one who dares not walk alone, but that of one who, when once having weighed the matter, respectfully gives his reasons, to be sure, but acts.
Another example of his independent artistic judgment is seen in his Tuscan arcade, which, almost with effrontery, pursues its way along the boundaries of the lawn, leaping upward or diving downward, daringly raps at the doors of each of the three orders of his classic temples. An architectural unit in itself surmounted by an anachronistic Chinese balustrade, what more incongruous in thought? Yet what more satisfying in beholding? This is not the work of a mere copyist, but of one having within him a feeling of confidence.
Jefferson's distance compensation in the perspective of his ensemble was equally as ingenious and effective as was that of the Greeks who curved the lines of their temple eaves. Standing in the south rotunda portico, looking down the lawn each unit, while maintaining its relationship, is nevertheless possessed of its individuality. He secured this by geometrically varying the diverging lines in two directions horizontal and vertical. Pavilions I and III and II and IV are spaced 89 feet, 8½ inches on centres; III and V and IV and VI are spaced 126 feet, 4½ inches on centres; V and VII and VI and VIII are spaced 143 feet, 6 inches on centres, and VII and IX and VIII and X are spaced 157 feet, 1 inch on centres. Thus he succeeds in holding apart the visual lines as they tend to approach each other with increasing distance in a horizontal plane. While between Pavilions V and VII and VI and VIII there is a fall of 3 feet, 2 inches, and between Pavilions VII and IX and VIII and X the fall is 4 feet, 6 inches, increasing the drop with increasing distance overcoming the tendency of vertical visual lines to approach each other. In this manner he secured for a group of buildings the same pleasing deception that the Greeks provided in a single temple with convex or concave eaves or stylobate in plan and elevation. A section of the lawn cannot be resolved into an inclined plane nor the elevation of its units reduced to an equally spaced grouping.
Vitruvius, and Palladio after him, had endeavored to discover some mathematical principle or exact expression for the classic proportions manifest in the various orders. Columnar proportions, for example, were laid down as eight, nine, and nine and one-half diameters for Doric, Ionic, and Corinthian respectively. In like manner proportions were established for entablatures and inter-columniations. Palladio's effort was a successful revolt against the license then rampant in European architecture, but being founded only in a half-truth it inevitably led to errors in an opposite direction. The proportions of the human figure when enlarged into the lengths and girths of a giant serve only to magnify the errors and obscure its harmonies. Painters have less often made this mistake. Michael Angelo's David suffers from mathematical enlargement, although its proportions are mathematically correct, whereas the scale of his painted figures has escaped criticism. As the treatment of St. Peter's held to arbitrary rules of proportion instead of multiplying its detail to give grandeur, the units were proportionately enlarged and extended, thus forcing upon the composition such monstrous treatment as is seen even in the vulgar and exaggerated scale of its Cupids, which, like great masses of putty, have been slammed against the bases of its columns. The result has dwarfed rather than glorified the scale of the composition. St. Paul's, while more successful, endeavored to escape this fault by the superposition one upon the other of its Corinthian orders. Jefferson, as an architect, discovered that beauty and dignity in art refused to be forced into arbitrary and inflexible moulds; that it demanded ease and freedom of movement; that while it had a measurable body, its spirit is not measurable by rule or square.
Vitruvius and Palladio failed to discover a mathematical rule because none existed. The better Roman architects must have worked out for each composition their proportions in design, modelling in plan and in elevation until their critical eye could discover no offense and until their artistic spirit found peace and satisfaction. It was then, and not until then, that any place was found for measuring and for mathematical proportion. The Temple of Vesta and the columns of Jupiter Stator are the two preëminent and faultless examples of the Corinthian order, yet neither of them conforms with Vitruvius's dicta and neither has a single proportion in common with the other. Were there a mathematical principle, architecture would be nothing more than mimicry and the disciple only a copyist. There would be no place for genius and the calling would cease to be an art.
Some laws there were (and are, to be sure) which bound the Roman architect, laws with a penalty more unescapable than any mathematical laws enunciated by Vitruvius, Palladio, or any archæological student. They were laws of art and not of mathematics. Therefore while Jefferson drew his types from Palladio, he did not copy him, as is seen in a few of his buildings:
| Diameters | ||
| Palladio and Vitruvius | Jefferson | |
| Diocletian Doric | 8. | 9.2 |
| Fortuna Virilis Ionic | 9. | 8.8 |
| Albano Doric | 8. | 8.5 |
| Theatre Marcellus Doric | 8. | 7.5 |
| Diocletian Corinthian | 9.5 | 9.5 |
Thus it is seen that only in one instance did he follow the mathematical maxims of Palladio and that in his Corinthian, whereas in the Doric of the Bath of Diocletian he diverged more than one diameter. These variations were requisite for what Jefferson conceived to be perfect proportions for his Tetra-style porticoes, which were of various dimensions. Examples of his artistic genius and of his artistic execution could be multiplied beyond number. Those given suffice the purpose of establishing his third or artistic qualification.
Morever, remembering that this work was executed nearly a century ago, we could supply evidence of his fourth qualification that of surveyor and engineer. The lawn itself, with its boundaries and its buildings, was laid out with transit and level manipulated by the hand of Jefferson. Architects of to-day are saved from this by later subdivisions of the sciences.
Architecture was only one of the many human interests with which Jefferson was identified in a most distinguished manner, and, whatever the subject, his relation to it was that of a diligent and discriminating student.
His talent in drawing, although far inferior to the splendid technique characteristic of the modern architect's office, and certainly very meagre as compared with the yards upon yards of blue-prints, elevations, sections, and full-size detail, is, however, despite these deficiencies, which were the limitations of the time rather than the man, clear, expressive, and intelligible. Nor should it be forgotten that the hand guiding the pen was more than seventy-five years old. Without the assistance of trained draftsmen, a handicap which he often deplored, he was loath to copy work which was injured by error or rendered useless by modification, and, as has been mentioned, this fact enables the student of his drawings to determine his order of sequence.
His discriminating selection of types, his genius in combination, the pleasurable exhilaration he produces in his daring but successful contrasts, the tranquillity secured by his harmony earn for him an incontestable place among artistic architects.
That he was able to take such classic models as the Temple of Fortuna Virilis, the Temple of Cori, and the Pantheon, reduce them, modify them, adjust them to a new setting, adapt them to a new purpose and to a different time, yet preserving with extreme fidelity the art in their lines and proportions, will perpetuate his fame as an architect with the power of splendid critical judgment. His was not the quickly grasped and drunken conception of the tyro, who with a few modillions, triglyphs, and metopes, a supply of columns, an assortment of capitals, and a few hundred yards of egg and dart moulding, would undertake the building of an institution for all men for all time. Nowhere does he sacrifice principle, practice rule-of-thumb, or bend to the cheapness of expediency. It was, therefore, with more than his usual characteristic optimism that he could disregard the critical cant of his own generation and leave the final judgment concerning his buildings to future ages. He reports to the Literary Board:
It is confidently believed that no considerable system of building within the U.S. has been done on cheaper terms, nor more correctly, faithfully or solidly executed according to the nature of the material used. That the style or scale of the buildings should have met the approbation of every individual judgment was impossible from the various structure of various minds. Whether it has satisfied the general judgment, is not known to us, no previous expression of that was manifested but in the injunctions of the law to provide for the accommodation of ten professors and a competent number of students; and by the subsequent enactments, implying an approbation of the plan reported by the original commissioners, on the requisition of the law constituting them; which plan was exactly that now carried into execution. We had, therefore, no supplementary guide but our own judgments, which we have exercised conscientiously, in adopting a scale and style of building believed to be proportioned to the respectability, the means and wants of our country and such as will be approved in any future condition it may attain. We owed to it to do, not what was to perish with ourselves, but what would remain, be respected and preserved thro other ages. And we fondly hope that the instruction which may flow from this institution, kindly cherished, by advancing the minds of our youth with the growing science of the times, and elevating the views of our citizens generally to the practice of social duties, and the functions of self government, may ensure to our country the reputation, the safety and prosperity, and all the other blessings which experience proves to result from the cultivation and improvement of the general mind. And without going into the monitory history of the ancient world, in all its quarters, and at all its periods, that of the soil in which we live, and of its occupants indigenous and immigrant, teaches us the awful lesson, that no nation is permitted to live in ignorance with impunity.
In these words, when his plans were completed, he uttered his prophetic hope; his buildings, having now reached the closing years of their first century, are only in their youth, and an appreciative posterity answers him in the affirmative.
Since writing the chapter on the University buildings, there has come into the possession of the author, through Dr. W. M. Randolph, a descendant of Jefferson, the notebook used on July 18, 1817, the day on which Jefferson staked out his plan on a virgin hill. The notes in this book bear further testimony: that Jefferson himself used the theodolite and staked out the plan; that he had at this time constructed his square or lawn; and that he modified the natural fall into grades which would accentuate his architectural perspective. The following is taken from the first page of this notebook:

In the same notebook is found an ingenious and interesting scheme for adapting his rotunda dome to the study of astronomy. He knew that it was impossible to secure a mechanic with the mathematical and astronomical training or an astronomer with the mechanical training and understanding to appreciate his scheme, so he writes his directions so plainly that he insures the results desired whether the undertaker be either a mechanic or an astronomer. To do this he must have understood mechanics better than the best mechanic of his time, and astronomy as well as the best astronomer. To either proposition there are many subscribers. A photograph of the page of his notebook will be interesting in illustrating his ingenuity in adapting a building to astronomical study. We wonder how many architects of to-day are prepared to attack similar problems.
The concave ceiling of the Rotunda is proposed to be painted sky-blue and spangled with gilt stars in their position and magnitude copied exactly from any selected hemisphere of our latitude. A seat for the Operator movable and fixable at any point in the concave, will be necessary, and means of giving to every star it's exact position.
Machinery for moving the Operator.
a. b. c. d. e. f. g. is the inner surface of 90 ° of the dome.
o. p. is a boom, a white oak sapling of proper strength, it's heel working in the centre of the sphere, by a compound joint admitting motion in any direction, like a ball and socket.
p. q. r. is a rope suspending the small end of the boom, passing over a pully in the zenith at q. and hanging down to the floor, by which it may be raised or lowered to any altitude.
at p. a common saddle, with stirrups is fixed for the seat of the operator, and seated on that, he may by the rope be presented to any point of the concave.
Machinery for locating the stars.
a. s. is the horizontal plane passing thro the centre of the sphere o. an annular ream of wood, of the radius of the sphere must be laid on this plane and graduated to degrees and minutes, the graduation beginning in the North rhomb of the place. Call this the circle of amplitude. a moveable meridian of 90 ° must then be provided, it's upper end moving on a pivot in the zenith, it's lower end resting on the circle of amplitude, this must be made of thin flexible white oak like the ream of a cotton spinning wheel, and fixed in it's curvature, in a true quadrant by a similar lath of white oak as it's chord a. n. their ends made fast together by clamps. This flexible meridian may be of 6 I. breadth, and graduated to degrees and minutes.
The zenith distance and amplitude of every star must then be obtained from the astronomical tables, place the foot of the moveable meridian in that of the North rhomb of the place, and the polar star at it's zenith distance, and so of every other star of that meridian; then move the foot to another meridian at a convenient interval, mark it's star by their zenith distance, and so go round the circle. bh. ci. dk. el. fm. are braces of window cord for keeping the meridian in it's true curve.
perhaps the rope had better be attached to the boom at s. instead of p. to be out of the way of the operator, perhaps also the chord board an. had better present it's edge to the meridian than it's side.
if the meridian ark and it's chord be 6 I. wide & ½ I. thick they will weigh about 135 lb. and consequently be easily manageable.
if the boom op. be 35 f. long, 6 I. at the but and 3. I. at the small end, it will weigh about 100 lb. and be manageable also.
While much of Mr. Jefferson's renown as an architect rests upon the success he attained in his monumental structures, he was not neglectful of obligation in those of less spectacular importance. As the President of the United States, before whom passed with the day's work a panorama of problems of national and absorbing interest, he found time to reflect upon the erection of chicken coops at his Pantops farm. He is unwilling to permit his granddaughter to erect a henhouse until the following summer when he shall have time to attend to its planning. In the construction of his own and his overseer's offices he bestows upon them the same absorbing attention as in the construction of Monticello. He is careful to force them into their proper spheres, by making the art of architecture proclaim and symbolize their function. They possess a dignity, but a dignity in harmony with their service. It was under such varied conditions that the brilliancy of his architectural genius shone. He used architecture for other purposes than shelter or gratification of the love of beauty. Always before him is the " eternal fitness of things." His structures announce their office with characteristic emphasis. A money-changer is a useful institution, but his vocation is not to be followed in the temple. He knew that the architecture of a church or chapel protected the structure and guaranteed its sanctity and that a barn on palatial lines cannot fail to jar the æsthetic sense.
Just before his death, but after he had completed all the plans for his democratic University, he began the consideration of plans for an astronomical observatory. As in all other problems he sought the experience of mankind. After consulting the plans of all the then existing similar structures, he commenced his rough draft (see Plate XX). On the back of the drawing he wrote his specifications. They are worthy of study, for they also give evidence of his knowledge of construction.
The 4 angular rooms of this drawing are 18 f. diam. in the clear & 18f. high. This dimension determines all the others. For an Observatory the material attentions are 1. that it be so solid in it's construction, with a foundation and walls so massive as not to be liable to tremble with the wind, walking, etc. 2. That it have ample apertures in every direction. 3. That it have some one position perfectly solid which may command the whole horizon and heavens; with a cupola cover, moveable and high enough to protect long telescopes from the weather. As to height of the building, the less the solider. The Observatories in the considerable cities of Europe are high of necessity to overlook the buildings of the place. That of Paris is 80.f. high. but so much the worse, if avoidable. In the design on the other side, the body of the building is surrounded with a terras of 70.f. square, 4½ f. high, to be filled solidly with stone laid dry and compact, and paved. all the rooms of the building are to be filled compactly with stone, in like manner to the floors, which should be paved. the doors of the 4 passages to be arched in order to unite the 4 octagon rooms together, and to form them into one solid body, all the walls to be 2½ bricks thick. those of the middle rooms to be vaulted together at top, and the hollow between the hemisphere and the square of the walls to be honeycombed with cross arches their crowns being made strait and level with the crown of the vault. this should rise a little above the top of the roof, so as to give a solid paved terras on the top which may command the whole horison. the Cupola cover should have a cylindrical body of thin light frame work moveable on pulley wheels at bottom in a circular groove, the top a hollow hemisphere, lightly ribbed and covered with tin, the two together high enough to cover a long refractor, of 15 f. for example. this moveable cover should be cut vertically into 2. halves from top to bottom, and the radius of one half should be less than that of the other, and move in an inner groove so that one may be shut into the other, leaving half of the vault of the heavens open to view, thus. over the wall of the mural quadrant must be a fissure in the roof closed with shutters water tight.
This building is proposed for the ordinary purposes of the Astronomical professor and his school, and should be placed on the nearest site proper for it, & convenient to the University. the hill on which the old buildi ngs stand seems to be the best.
The mountain belonging to the University was purchased with a view to a permanent establishment of an Observatory, with an Astronomer resident at it, employed solely in the business of Observation. but I believe a site on the nearest mountain in the S.W. ridge, Montalto for example would be better, because of it's command of the fine horison to the East.
On the margin of this plan he portrays his sterling honesty. After having drawn them he found a scheme better adapted to the function, so he stamps upon his own scheme his emphatic condemnation in these words:
See an infinitely better plan by Hassler in the Am. Philosoph. transaction, new series, vol II. Pl. X 1825. See Observatory of Paris 2. Miliria. p.A; 187 Pl IX.c
The writer has had much practical experience with the architects of to-day and has found them exceptionally sincere in being willing to surrender the wrong and grasp the correct, quick to abandon their own error and follow another's truth, but he is not sure that in making the transition they would, all of them, tarry long enough to put the stamp of their own condemnation upon their own work.
Jefferson's interest in art and monumental architecture is clearly portrayed in his letter to the Comtesse de Tesse while on a tour through Southern France. It also discloses in words, as the University buildings proclaim in works, his slant toward the Roman art.
Nismes, March 20th 1787.
Here I am, Madam, gazing whole hours at the Maison Quarree, like a lover at his mistress. The stocking weavers and silk-spinners around it consider me as a hypochondriac Englishman, about to write with a pistol the last chapter of his history. This is the second time I have been in love since I left Paris. The first was with a Diana at the Chateau de Laye-Espinaye in Beaujolais, a delicious morsel of sculpture, by M. A. Slodtz. This you will say, was in rule, to fall in love with a female beauty; but with a house! It is out of all precedent. No, madam, it is not without a precedent in my own history. While in Paris, I was violently smitten with the Hotel de Salm, and used to go to the Fisheries almost daily to look at it. The loueuse des chaises inattentive to my passion never had the complaisance to place a chair there, so that sitting on the parapet, and twisting my neck around to see the object of my admiration, I generally left it with a torti-coli.
From Lyons to Nismes I have been nourished with the remains of Roman grandeur. They have always brought you to my mind because I know your affection for whatever is Roman and noble. At Vienne I thought of you. But I am glad you were not there; for you would have seen me more angry than, I hope, you will ever see me. The Prætorian Palace as it is called comparable, for its fine proportions, to the Maison Quarree defaced by the barbarians who have converted it to its present purpose, its beautiful fluted corinthian columns cut out, in part, to make space for Gothic windows, and hewed down, in the residue, to the plane of the building, was enough, you must admit, to disturb my composure. At Orange, too, I thought of you. I was sure you had seen with pleasure the sublime triumphal arch of Marius at the entrance to the city. I went then to the Arenæ. Would you believe, Madam, that in this eighteenth century, in France under the reign of Louis XVI., they are at this moment pulling down the circular wall of this superb remain, to pave a road? And that, too, from a hill which is itself an entire mass of stone, just as fit, and more accessible!
An evidence of Jefferson's resourcefulness is seen in his plan and specifications for a bell-clock which would work automatically. This must be arranged so that the bell can be struck by the operation of the clock machinery and yet it must be possible for the bell-ringer voluntarily to ring it at any hour. He secures this feature by fixing the bell so as to prevent its motion from disturbing the hammers within it. one of which is connected to the clock machinery by a wire and moves in one plane to make its stroke, the other is attached to a bell-rope to be voluntarily operated by the bellringer, and moves in a plane at right angles to the other. His rough sketch will make his mechanism plain. (See Plate XXI.) He calculates the spaces in its dial for hours and minutes, determines the length of the pendulum, improvises a ratchet key for its winding, specifies the weights for its momentum and details the mechanism for its escapement. The clock operated perfectly until it was destroyed in the fire of 1895. Will another survive so long?
It is not easy for those of our time to appreciate the many and the varied character of the difficulties that confronted Jefferson in his building operations.
The settlement at Charlottesville was too small to give aid in the way of mechanics' or of builders' supplies, consequently nearly every article for such purposes and even many of those things needed in everyday life must be made upon the farm. He taught some of the negroes to become good cabinetmakers, carpenters, stonecutters, bricklayers, and blacksmiths. He employed the pickaninnies in a miniature nail factory, which, beside supplying nails for his own use, furnished a surplus to be sold for profit in the neighboring village. In order to accomplish this he stimulated ambition by keeping in operation a system of rewards, distinctions, and promotions amongst those in the handicrafts. He sought out his own clay and made moulds for his brick after providing for shrinkage in burning. He personally investigated the native woods as to color, durability, and adaptability to the various building purposes. He experimented with mortar, seeking to produce one that would stand the dampness of underground tunnels and basement walls. He tried all manner of mixtures of lime, sand, and oils. He knew it could be done, for the Romans had left the Cloaca Maxima as evidence. His conclusions were, in his own words, "1 bushel each of lime, wood ashes and pulverized bricks brought to the proper consistence will harden in water," as he left them on the margin of a sheet of notes to his builders. That it did harden, all the plumbers and steam-fitters who have had to cut through his basement walls will testify. The oxide of lime with the potash which came from his burned wood ashes and his silica and alumina from his incinerated bricks gave the chemicals which the modern man has discovered are requisite for hydraulic cement, in which the following reaction is supposed to take place:
CaO + H2O = Ca (HO)2
3Ca (HO)2 + SiO2 = Ca3SiO5 + 2H2O.
He discovered that kiln-drying lumber injured its quality, made it brittle, and favored splintering; for this reason he specified that all flooring and finishing for cornices, windows, and inside trim should be air-dried for two years and followed by one year's seasoning under shelter. He directed the method by which his carpenter's glue was to be made from fresh hides in a pot which itself must rest in another pot of boiling water, in order, as he says, that the adhesiveness may not be lost by excessive heat, and that scorching may not destroy its light color. He made up his own mind about mixing paints and if nineteen and one-half pounds measured more than a gallon he insisted on further stirring.
Such as essayed to do the work of the architect during Jefferson's time were only amateurs, who with an itinerant habit migrated from place to place, to the seat of construction, because they were never able to communicate their ideas by either verbal or graphic instruction. They were in fact builderarchitects who did not foresee difficulties, but attempted the solution of building problems only as they arose. Jefferson, on the other hand, while he never neglected personal supervision, communicated his ideas in such exact terms, and in such order of succession, that if faithful adherence was observed the building in his mind would result and none other. No word was ever written which could be omitted, and none which was left out could be added without endangering the successful achievement of the conception.
In 1792, when the United States, a fledgling nation, found itself in need of governmental buildings, advertised for plans for a national "Capitol," a great number were offered, prepared by those who were anxious to secure the prize of five hundred dollars and a city lot, Hoban, Thornton, and "Judge Turner" being among the contestants. The winner was William Thornton. We assume that the victor presented the best plans of the best building, yet history records that the victorious plans were not plans at all only perspective sketches, such as from which any one of forty different buildings might have been constructed. There were neither ground plans, elevation, nor sections, but only pictures which the Commissioners were forced to choose from. It would be as unfair to contrast the work of the professed architect of that time with the work of a powerfully trained mind like Jefferson's as it would be to pit the pygmy against the giant.
The abiding integrity of Jefferson's building operations, his honesty in construction, his resourcefulness in the combination of materials, his ingenuity in their adaptation, his accurate observation, his scientific slant of mind, his versatility in information, his powers of discrimination, his sense of proportion, all combined with a bigness of mind and an artistic temperament, lifted him at once as an architect from competition with all his contemporaries.
In his main hall at Monticello, Jefferson could face the embers in his grand fireplace, watch the laborers on his Pantops farm, observe the direction of the wind which by his ingenuity was registered in the ceiling of his portico, read the atmospheric pressure on a barometer constructed by his own hands, compare the external and internal temperature on a double thermometer from his own specifications, and observe the hour on the face of the great hall clock, whose pendulum, escapement, weights, and regulators were built under his personal directions.
To be sure it would be unfair to expect the specialized architect of our day to embody in his equipment such varied qualifications as the old statesman-architect possessed, just as it would be unfair to demand of Jefferson such splendid detail as the modern specialized architect offers. Yet out of the continuous stream of architects who pass his work in review, not one has departed without paying a graceful tribute to his supremacy. Stanford White, when asked why he did not locate his buildings nearer the old Jefferson group, replied in all sincerity that such temerity must be reserved for a more audacious architect.
It is a tribute to the profession of our own generation that, notwithstanding the development of their science and the specialization of their tasks, they maintain a reverence for those who labored under the limiting conditions of the past. And nowhere in their history have they found a figure standing for a higher truth or maintaining a nobler ideal. As future generations of architects, reviewing and in review, file past his work, they will bare their heads to his fidelity to their art, acknowledge him as the pioneer in an infant profession, and with one acclaim hail the Godfather of the American Architect.

Mr. Jefferson's writings, his University of Virginia, his Monticello, give unmistakable evidence of his appreciation of landscape, of the value of buildings as elements of landscape, and of the relation that they should bear to the topography and to the outlook of a site.
Had he not loved and appreciated landscape, he would not have said, "And our own dear Monticello, where Nature has spread such a rich mantle under the eye, mountains, forests, rocks, rivers. There is a mountain there in the opposite direction of the afternoon's sun, the valley between which and Monticello, is five hundred feet deep." "How sublime to look down upon the workhouse of Nature to see her clouds, hail, snow, rain, thunder, all fabricated at our feet."
In his outline of the University curriculum in the letter of September 7, 1814, to Peter Carr, President of the Board of Trustees, he designated as his third division, Professional Grades, stating that to the Professional School would come among others, the "agricultor"; to the Department of Rural Economy, the gentleman, the architect, the pleasure gardener, painter, and musician. In the School of Fine Arts he included Gardening, Painting, Sculpture, Civil Architecture, and the Theory of Music.
Thus in the educational forecast of his greatest monument, the University of Virginia, and in the design of his home as indicated elsewhere, does Jefferson recognize the broader phases of landscaping which at that time was no more clearly differentiated in the popular mind, from gardening, architecture, horticulture, or engineering, than it is to-day.
In Mr. Jefferson's day, the most important constructive work of his century, as well as the classics of the profession that deals with landscape, was being produced in England by such practitioners and writers as Repton, Kent, Price, Gilpin, Pope, and Addison. Of the books then produced, the late Frederick Law Olmsted, the master mind of this profession in America, first placed in the hands of his students Wheatley's "Observations on Modern Gardening." With this book in hand, Mr. Jefferson made "A tour to some of the English gardens" in March and April, 1776, made "chiefly," he states, "for such practical things as might enable me to estimate the expenses of making and maintaining a garden of that style." He says that Wheatley's descriptions "are, in point of style, models of perfect elegance and classical correctness; they are as remarkable for their exactness." Mr. Jefferson, in his own description of these gardens, intelligently and discriminatingly comments upon the merits and defects of the English landscapes and the buildings therein, as he did in earlier notes on travels in France.
There was included with this knowledge and appreciation of the fine arts, a practical interest in and an intimate knowledge of the mechanical devices and methods, and the materials used in the construction of buildings and landscapes. The sketches in his notes of travel, his letters to friends, his minute instructions to his farm superintendent regarding the farming and manufacturing at his Monticello, and the plans and directions for the construction of the University made with his own hands, give abundant evidence of this. He was a skillful surveyor, too, for he in person surveyed and drew the plans of his own estates and the University site. His engineering knowledge enabled him to bring the University water-supply from basins fed with surface and spring water "in wooden pipes from the neighboring high lands," and also to seek for a contingent supply, as indicated by his inquiries "for a person acquainted with the art of boring for water to immense depths. We have occasion for such an artist at our University."
Mr. Jefferson's interest in city planning is also indicated in his letter of February 8, 1805, in which he refers to yellow fever as originating in low, ill-cleansed parts of the town and suggests a "checker-board plan" in which "black squares only to be building squares, and the white ones to be open in turf and trees." "I have accordingly proposed that the enlargement of New Orleans which must immediately take place shall be upon this plan."
That Mr. Jefferson's "garden" and "gardening" represented in his mind what we term "landscape," is indicated by the statement in his "traveling notes" of June 3, 1788, to young friends who were going abroad; "Gardens [are] peculiarly worth the attention of an American, because it is the country of all others where the noblest gardens may be made without expense. We have only to cut out the superabundant plants."
The most notable example of Jefferson's own cutting out of the super-abundant plants to make a landscape is to be observed on the road through his estate from Charlottesville to Monticello. This road, after leaving the village, crosses a tree-arched stream, then follows its shore for some distance before beginning its hillside climb. At a point a little more than halfway up to the saddle of the ridge which is terminated by Monticello is one spot which I conceive was sought out by Jefferson with much woods tramping and tree-climbing to establish viewpoints. Here the steep forested hillside towers uphill above you, and grassy fields fall steeply downhill away from you. To the right is the edge of the Monticello thirty-acre hilltop forest, from which Mr. Jefferson refused to allow the cutting of trees in his day, but which was cut, together with many of his lawn trees, before 1835 by Barkley before it was purchased by Lieutenant Uriah Levy. The edge of the forest touched just the right point on the horizon, and its height increased the depth of the valley below. To the left, a narrow strip of trees was left on the steep roadside bank. Well out and down the slope, and a little to the left of the picture centre, is a group of tall trees with branches sweeping up and out in a quick graceful curve that repeats the down sweeps of the grassy base of the knoll on which they stand. At the foot of the long slope winds the tree-fringed thread of the creek. Then come houses smothered in the trees of the valley. All this is the frame, the foreground, the middle distance with the range of the mountains against the sky. These mountains are made to appear very high by this view over the deep valley and its steep slopes, and between a flaring frame of tall trees, whereas over flat land from the same elevation they would have been rather unimpressive high hills.
The road from here soon passes into the woods, and to the entrance lodge that lies in the saddle of the ridge. From here there is a rather steep climb on a great curve through a wood with a Scotch broom undergrowth by Jefferson's monument to his home. Not far from the lodge the return branch road, recently constructed, is passed on the right, but its point of departure and angle are so skillfully taken off from the direct uphill road that one is not likely to notice it at all in going up. So, too, is the return road taken off from the inward approach soon after leaving the house and gardens. This down road winds around the slope and by the head of a small valley to the intersection point near the gate lodge. Both roads and the views therefrom lie wholly within the thirty-acre woods, for Jefferson reserved his next fine views for the house site. These views include three great valleys with the Blue Ridge twenty-five miles away, the course of which marks the horizon for eighty miles in view, as well as the Ragged Mountains on the south in the approach-road view.
The house is located just far enough back from the point of the ridge summit to make way for a sweep of gently sloping lawn where a large party of people and their vehicles could gather, turn, and move about. This was made distinctly the entrance side of the house. The house main floor elevation was fixed at a point where its occupants could look over a lawn one hundred and ten feet wide and one hundred and fifteen feet long. From near its floor level, platforms extend east and west to the edge of the retaining wall that holds a part of the south lawn quadrangle in place. This retaining wall extends back to office building terminals on each side, beyond which the lawn surface merges into the natural slope. Along the face of the west part of the retaining wall was storage space. Along the face of the east part are the servants' quarters, and to each of these apartments went passages from the house basement under the platform. At the ends of these platforms were outlook points from which are magnificent views, west, north, and east, into valleys and on to distant hills.
From the point where the two roads through the woods meet near the south end of the lawn, the drive passed on a direct and level line, by the ivy-covered ruins of old buildings, then by the terraced kitchen garden on the steep easterly slope at the right, and then on to the farm. These kitchen gardens were constructed mostly during the period when Mr. Jefferson was President of the United States. His overseer states that there were grown here "vegetables of all kinds, figs, grapes, and the greatest variety of fruit." On the west of this entrance road as it passed the house, the terrace at the servants' quarter level was high enough up above the road so that activities thereon could be screened from visitors on foot or in vehicle by a low hedge.
The sunny south lawn was the home lawn where Jefferson and his family were completely protected from the intrusion of visitors who might come in by the only entrance road.
It is not necessary to go further in the description of Monticello to show this man's genius as a designer of a notable home estate plan, except to say that he gave as much attention to the tree and shrub planting as to other features. Captain Edmund Bacon, who for twenty years was the Monticello overseer, received such written instructions as these: Plant "four Purple Beeches in the clumps which are in the southwest and northwest angles of the houses. The places will be known by the sticks marked No. IV." There were similar notes regarding "Robinias, or Red Locust," "Prickly Ash," "Thorns for Hedges, Fruit Trees, Pecan Nuts," and "Some turfs of a particular grass." Bacon states that Mr. Jefferson always knew everything in every part of his grounds and garden, the name of every tree and just where one was dead or missing. He also states that the grounds about the house were most beautifully ornamented with flowers and shrubbery. There were walks and borders of flowers, some of them in bloom from early in the spring until late in the winter, and a good many were foreign.
The development of the home estate plan and the building of the house extended over a thirty-year period that followed 1764, yet I find no evidence of radical departures from his first conceptions. Study the topography of this section, and you will see that he selected the most commanding of its conveniently accessible sites, certainly the finest site on his father's thirty thousand acres. He clearly recognized in the beginning the big units in the natural beauty of the site, the relation that the house, its approaches, and the outdoor compartments about it should bear to this beauty, as well as to the convenience and comfort of his family and his visitors.
One of the most important of these landscape units was "the valley five hundred feet deep," the Charlottesville Valley, his "sublime workhouse of Nature." It was here that the site of the University of Virginia was officially located August 1, 1818, on a ridge, where the College Trustees had directed on May 5, 1817, that the first building should be erected. The beauty of this valley had so appealed to Mr. Jefferson, and his conception of the relation of building to landscape was so broad, that he must have had definitely in mind, during all these constructive years, the visual connection between his first love "Monticello" and the University, of which he expressed his desire to be called the father, in the epitaph which he wrote. At his home the westerly slope below the house and its south lawn were cleared of trees and laid in grass. This gave an unobstructed view of the University. On that side of the University ridge that faced Monticello, the outbuildings and the ranges were stepped down the slope to give views over their tops down into the valley and up to Monticello from the professors' quarters in the second story of the pavilion on the East Lawn, as well as from the students' quarters in the East Range. This arrangement presented the most effective architectural grouping to Jefferson and his friends as they looked down into the valley and to the College group from the home.
In the design of the College, Mr. Jefferson had the benefit of foreign travel and the intercourse with distinguished men and women that his position as Ambassador to France and as President of this United States gave him, advantages that had not come to him when he conceived Monticello's plan. This intercourse and his study of this plan gave rise to expressions that represented his appreciation of landscape and its place in design that I have referred to at the outset. While this intercourse aided him in the development of his University plan, it did not impair his originality of thought or independence of action, or his power of adapting the conceptions of others to his special problems without making servile copies. Not only was this true in the units of his plan, but also in his terms of identification, such as "The Lawns," "The Ranges," "The Pavilions."
In Mr. Jefferson's letter of September 7, 1814, to Peter Carr, he states that "In his acquaintance with the organization of the seminaries of other countries and with the opinions of the most enlightened individuals he found no two alike, each being adapted to the condition of the section or society for which they have been framed. No one could be adopted without change in our country."
His statement of April 2, 1821, with many reasons why a "Village form is preferable to a single great building," forecasts a plan which Mr. Herbert B. Adams refers to as the "modern adaptation of the mediæval idea of cloistered retreats, with colonnades and quadrangles, the latter opening toward the south."
May 5, 1817, the Trustees directed the erection of buildings in accordance with a plan presented "for buildings about a square." Four days later Mr. Jefferson delineated his connected pavilions and dormitories on three sides of a "square" opening south, "with trees and grass," in a letter to Mr. William Thornton. This letter is reproduced in Dr. Lambeth's chapter. On January 6, 1818, the Trustees described the purchase of land "high, dry, open, and furnished with water," and a plan which provided for adding to the buildings "indefinitely hereafter," "the whole in form and effect" to have "the character of an academical village."
On August 1, 1818, a legislative commission meeting at Rock Fish Gap in the Blue Ridge approved the site and the plans, with the knowledge that "one pavilion and its appendix of dormitories" were far advanced and another under way, and that the one hundred and fifty-three acres of land that were added to the or "a considerable eminence" for the erection of a future observatory. This observatory Mr. Leander McCormick, of Chicago, did erect in 1880-81.
Referring again to the reproductions in Dr. Lambeth's chapters, it will be observed that Mr. Jefferson in his first plan located the ranges (dormitories) close to the rear of the lawn, class-room and professors' homes (pavilions), with gardens at the back of the ranges, and then ingeniously reversed the gardens on his plan to bring them between the ranges and lawns by cutting out and reversing a part of his drawing. This last arrangement permitted a direct access by stairs to the gardens from the professors' homes in the second story of the pavilions which were included in one plan and partly built, as indicated by Dr. Lambeth. The service road and yard, used in common by two pavilions, were shut off from the gardens by the serpentine walls. Thus you will see he provided a secluded outdoor compartment for professors' families that corresponded to his Monticello south lawn.
Regarding these changes, Mr. J. C. Cabel, who was Mr. Jefferson's most helpful legislative co-worker, but whose criticism on the style and constructions of buildings were generally not accepted, says, "I was extremely happy to be info
