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.
