"My next instruction was to get ten able-bodied hands to commence the work.... Mr. Jefferson started from Monticello to lay off the foundation, and see the work commenced. An Irishman named Dinsmore, and I, went along with him. As we passed through Charlottesville, I ... got a ball of twine, and Dinsmore found some shingles and made some pegs.... Mr. Jefferson looked over the ground some time, and then stuck down a peg.... He carried one end of the line, and I the other, in laying off the foundation of the University. He had a little ruler in his pocket that he always carried with him, and with this he measured off the ground, and laid off the entire foundation, and then set the men at work." This foot-rule was shown to Dr. Pierson by Mr. Bacon, who explained how he secured it: "Mr. Jefferson and I were once going along the bank of the canal, and in crawling through some bushes and vines, it [the ruler] fell out of his pocket and slid down the bank into the river. Some time after that, when the water had fallen, I went and found it, and carried it to Mr. Jefferson. He told me I ... could keep it.... When I die, that rule can be found locked up in that drawer. "After the foundations were nearly completed, they had a great time laying the corner-stone. The old field was covered with carriages and people. There was an immense crowd there. Mr. Monroe laid the corner-stone. He was President at that time.... He held the instruments, and pronounced it square. I can see Mr. Jefferson's white head just as he stood there and looked on. "After this he rode there from Monticello every day while the University was building, unless the weather was very stormy.... He looked after all the materials, and would not allow any poor materials to go into the building if he could help it." A letter from Jefferson to John Adams, written on October 12, 1823, spoke of the "hoary winter of age." "Against this _tedium vitae_," he said, "I am fortunately mounted on a hobby, which, indeed, I should have better managed some thirty or forty years ago; but whose easy amble is still sufficient to give exercise and amusement to an octogenary rider. This is the establishment of a University, on a scale more comprehensive, and in a country more healthy and central than our old William and Mary, which these obstacles have long kept in a state of languor and inefficiency." In designing the buildings Jefferson acknowledged his indebtedness to Palladio, who guided him in his adaptation of Roman forms. The visitor who is familiar with Rome is reminded of the baths of Diocletian, the baths of Caracalla, and the temple of Fortuna Virilis, while a reduction of the Pantheon, with a rotunda, is the central feature of the group.
