"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."
