Henry David Thoreau Quote
One farmer says to me, "You cannot live on vegetable food solely, for it furnishes nothing to make the bones with;" and so he religiously devotes a part of his day to supplying himself with the raw material of bones; walking all the while he talks behind his oxen, which, with vegetable-made bones, jerk him and his lumbering plow along in spite of every obstacle.
Walden (ed. 1882)
