So Silas walked back and forth, and sang, and spouted "pieces," and mused on the future of his life, and spouted "pieces" again, and sang in the loneliness. How the time passed, he did not know. No sound of clock, no baying of dog, no plash of waterfall, broke that utter stillness. The wind, thank God, had at last died away; and Silas paced his beat in a long oval he made for himself, under and beyond the bridge, with no sound but his own voice when he chose to raise it. He expected, as they all did, that every moment the whistle of the train, as it swept into sight a mile or more away, would break the silence; so he paced, and shouted, and sang. "This is a man's duty," he said to himself: "they would not let me go with the fifth regiment,--not as a drummer boy; but this is duty such as no drummer boy of them all is doing. Company, march!" and he "stepped forward smartly" with his left foot. "Really I am placed on guard here quite as much as if I were on picket in Virginia." "Who goes there?" "Advance, friend, and give the countersign." Not that any one did go there, or could go there; but the boy's fancy was ready, and so he amused himself during the first hours. Then he began to wonder whether they were hours, as they seemed, or whether this was all a wretched illusion,--that the time passed slowly to him because he was nothing but a boy, and did not know how to occupy his mind. So he resolutely said the multiplication-table from the beginning to the end, and from the end to the beginning,--first to himself, and again aloud, to make it slower. Then he tried the ten commandments. "Thou shalt have none other Gods before me:" easy to say that beneath those stars; and he said them again. No, it is no illusion. I must have been here hours long! Then he began on Milton's hymn:-- "It was the winter wild, While the heaven-born child, All meanly wrapt, in the rude manger lies." "Winter wild, indeed," said Silas aloud; and, if he had only known it, at that moment the sun beneath his feet was crossing the meridian, midnight had passed already, and Christmas day was born! "Only with speeches fair She wooes the gentle air To hide her guilty front with innocent snow." "Innocent, indeed," said poor Silas, still aloud, "much did he know of innocent snow!" And vainly did he try to recall the other stanzas, as he paced back and forth, round and round, and began now to wonder where his father and the others were, and if they could have come to any misfortune. Surely, they could not have forgotten that he was here. Would that train never come?
