I recall the time when I lived on a vast vacant level green plain, an earth which to the eye, and to the mind which sees with the eye, appeared illimitable, like the ocean; where the house I was born in was the oldest in the district--a century old, it was said; where the people were the children's children of emigrants from Europe who had conquered and colonized the country, and had enjoyed but half a century of national life. But the people who had possessed the land before these emigrants--what of them? They, were but a memory, a tradition, a story told in books and hardly more to us than a fable; perhaps they had dwelt there for long centuries, or for thousands of years; perhaps they had come, a wandering horde, to pass quickly away like a flight of migrating locusts; for no memorial existed, no work of their hands, not the faintest trace of their occupancy. Walking one day at the side of a ditch, which had been newly cut through a meadow at the end of our plantation, I caught sight of a small black object protruding from the side of the cutting, which turned out to be a fragment of Indian pottery made of coarse clay, very black, and rudely ornamented on one side. On searching further a few more pieces were found. I took them home and preserved them carefully, experiencing a novel and keen sense of pleasure in their possession; for though worthless, they were man's handiwork, the only real evidence I had come upon of that vanished people who had been before us; and it was as if those bits of baked clay, with a pattern incised on them by a man's finger-nail, had in them some magical property which enabled me to realize the past, and to see that vacant plain repeopled with long dead and forgotten men.
