All this went along with great and continued political excitement, and with some glimpses of the social problem. It was very simple then; nobody was very rich, and nobody was in want; but somehow, as the boy grew older, he began to discover that there were differences, even in the little world about him; some were higher and some were lower. From the first he was taught by precept and example to take the side of the lower. As the children were denied oftener than they were indulged, the margin of their own abundance must have been narrower than they ever knew then; but if they had been of the most prosperous, their bent in this matter would have been the same. Once there was a church festival, or something of that sort, and there was a good deal of the provision left over, which it was decided should be given to the poor. This was very easy, but it was not so easy to find the poor whom it should be given to. At last a hard-working widow was chosen to receive it; the ladies carried it to her front door and gave it her, and she carried it to her back door and threw it into the alley. No doubt she had enough without it, but there were circumstances of indignity or patronage attending the gift which were recognized in my boy's home, and which helped afterwards to make him doubtful of all giving, except the humblest, and restive with a world in which there need be any giving at all.
III. THE RIVER.
It seems to me that the best way to get at the heart of any boy's town is to take its different watercourses and follow them into it.
The house where my boy first lived was not far from the river, and he must have seen it often before he noticed it. But he was not aware of it till he found it under the bridge. Without the river there could not have been a bridge; the fact of the bridge may have made him look for the river; but the bridge is foremost in his mind. It is a long wooden tunnel, with two roadways, and a foot-path on either side of these; there is a toll-house at each end, and from one to the other it is about as far as from the Earth to the planet Mars. On the western shore of the river is a smaller town than the Boy's Town, and in the perspective the entrance of the bridge on that side is like a dim little doorway. The timbers are of a hugeness to strike fear into the heart of the boldest little boy; and there is something awful even about the dust in the roadways; soft and thrillingly cool to the boy's bare feet, it lies thick in a perpetual twilight, streaked at intervals by the sun that slants in at the high, narrow windows under the roof; it has a certain potent, musty smell. The bridge has three piers, and at low water hardier adventurers than he wade out to the middle pier; some heroes even fish there, standing all day on the loose rocks about the base of the pier. He shudders to see them, and aches with wonder how they will get ashore. Once he is there when a big boy wades back from the middle pier, where he has been to rob a goose's nest; he has some loose silver change in his wet hand, and my boy understands that it has come out of one of the goose eggs. This fact, which he never thought of questioning, gets mixed up in his mind with an idea of riches, of treasure-trove, in the cellar of an old house that has been torn down near the end of the bridge.
On the bridge he first saw the crazy man who belongs in every boy's town. In this one he was a hapless, harmless creature, whom the boys knew as Solomon Whistler, perhaps because his name was Whistler, perhaps because he whistled; though when my boy met him midway of the bridge, he marched swiftly and silently by, with his head high and looking neither to the right nor to the left, with an insensibility to the boy's presence that froze his blood and shrivelled him up with terror. As his fancy early became the sport of playfellows not endowed with one so vivid, he was taught to expect that Solomon Whistler would get him some day, though what he would do with him when he had got him his anguish must have been too great even to let him guess. Some of the boys said Solomon had gone crazy from fear of being drafted in the war of 1812; others that he had been crossed in love; but my boy did not quite know then what either meant. He only knew that Solomon Whistler lived at the poor-house beyond the eastern border of the town, and that he ranged between this sojourn and the illimitable wilderness north of the town on the western shore of the river. The crazy man was often in the boy's dreams, the memories of which blend so with the memories of real occurrences: he could not tell later whether he once crossed the bridge when the footway had been partly taken up, and he had to walk on the girders, or whether he only dreamed of that awful passage. It was quite fearful enough to cross when the footway was all down, and he could see the blue gleam of the river far underneath through the cracks between the boards. It made his brain reel; and he felt that he took his life in his hand whenever he entered the bridge, even when he had grown old enough to be making an excursion with some of his playmates to the farm of an uncle of theirs who lived two miles up the river. The farmer gave them all the watermelons they wanted to eat, and on the way home, when they lay resting under the sycamores on the river-bank, Solomon Whistler passed by in the middle of the road, silent, swift, straight onward. I do not know why the sight of this afflicted soul did not slay my boy on the spot, he was so afraid of him; but the crazy man never really hurt any one, though the boys followed and mocked him as soon as he got by.
The boys knew little or nothing of the river south of the bridge, and frequented mainly that mile-long stretch of it between the bridge and the dam, beyond which there was practically nothing for many years; afterwards they came to know that this strange region was inhabited. Just above the bridge the Hydraulic emptied into the river with a heart-shaking plunge over an immense mill-wheel; and there was a cluster of mills at this point, which were useful in accumulating the waters into fishing-holes before they rushed through the gates upon the wheel. The boys used to play inside the big mill-wheel before the water was let into the Hydraulic, and my boy caught his first fish in the pool below the wheel. The mills had some secondary use in making flour and the like, but this could not concern a small boy. They were as simply a part of his natural circumstance as the large cottonwood-tree which hung over the river from a point near by, and which seemed to have always an oriole singing in it. All along there the banks were rather steep, and to him they looked very high. The blue clay that formed them was full of springs, which the boys dammed
