Yet when the last week of April came, and the grass in the little square around the corner was green again, and the shrubs were beginning to flower out, the sick man also felt his vigor returning. His strength came back with the spring, and restored health sent fresh blood coursing through his veins as the sap was rising in the branches of the tree before his window. He had had a hard struggle, he knew, although he did not suspect that more than once he had wrestled with death itself. Now his appetite had awakened again, and he had more force to withstand the brooding sadness which sought to master him. The tree before his window was but a shabby sycamore, and the window belonged to a hall bedroom in a shabby boarding-house down a side street. The young man himself lay back in the steamer chair lent him by one of the few friends he had in town, and his overcoat was thrown over his knees. His hands, shrunken yet sinewy, lay crossed upon a book in his lap. His body was wasted by sickness, but the frame was well knit and solid. His face was still white and thin, although the yellow pallor of the sick-bed had gone already. His scanty boyish beard that curled about his chin had not been trimmed for two months, and his uncut brown hair fell thickly on the collar of his coat. His dark eyes bore the mark of recent suffering, but they revealed also a steadfast soul, strong to withstand misfortune. His room was on the north side of the street, and the morning sun was reflected into his window, as he lay back in the chair, grateful for the warmth. A heavy cart lumbered along slowly over the worn and irregular pavement; it came to a stand at the corner, and a gang of workmen swiftly emptied it of the steel rails it contained, dropping them on the sidewalk one by one with a loud clang which reverberated harshly far down the street. From the little knot of men who were relaying the horse-car track came cries of command, and then a rail would drop into position, and be spiked swiftly to its place. Then the laborers would draw aside while an arrested horse-car urged forward again, with the regular footfall of its one horse, as audible above the mighty roar of the metropolis as the jingle of the little bell on the horse's collar. At last there came from over the house-tops a loud whistle of escaping steam, followed shortly by a dozen similar signals, proclaiming the mid-day rest. A rail or two more clanged down on the others, and then the cart rumbled away. The workmen relaying the track had already seated themselves on the curb to eat their dinner, while one of them had gone to the saloon at the corner for a large can of the new beer advertised in the window by the gaudy lithograph of a frisky young goat bearing a plump young goddess on his back.
