Compare with Jefferson's own account of his activities at Monticello:
"My mornings are devoted to correspondence. From breakfast to (afternoon) dinner, I am in my shops, my garden, or on horseback among my farms; from dinner to dark, I give to society and recreation with my neighbors and friends; and from candlenight to early bedtime, I read...I talk of ploughs and barrows, seeding, and and harvesting, with my neighbors, and of politics too...I endeavor to keep their attention fixed on the main objects of all science, the freedom and happiness of man."
Letter to Thaddeus Koscinsko, February 26, 1810. Quoted from: Vickery, Robert. The Meaning of the Lawn, p.32.
