They were pleasant spring days, in which the winter of man's discontent was thawing as well as the earth, and the life that had lain torpid began to stretch itself.

East of my bean-field, across the road, lived Cato Ingraham, slave of Duncan Ingraham, Esquire, gentleman, of Concord village, whobuilt his slave a house, and gave him permission to live in Walden Woods;MCato, not Uticensis, but Concordiensis. Some say that he was a Guinea Negro. There are a few who remember his little patch among the walnuts, which he let grow up till he should be old and need them; but a younger and whiter speculator got them at last. He too, however, occupies an equally narrow house at present.

He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws.

Mathematics should be mixed not only with physics but with ethics; that is mixed mathematics. The fact which interests us most is the life of the naturalist. The purest science is still biographical.
