She, likewise, at the signal, made a mental image of Tom, seated in the engine cab, his one hand fixed upon the shining lever, his eyes fixed upon the glistening tracks ahead. At six o'clock, usually, supper was hot, and Tom arrived through the front gateway, glancing at the flower-bed in the centre of the diminutive grass plot, carrying his dinner-pail, having divested himself of his grimy, greasy blouse and overalls at the great repair shops, where his engine had already begun, with much panting, to spend the night. In a small railroad town on the main line, one is continually hearing locomotive whistles. All the inhabitants know that one long moan of the steam is the signal of the train's swift approach; that two short shrieks of the whistle direct the trainmen to tighten the brakes; that four, given when the train is still, are intended for the flagman, who has gone away to the rear to warn back the next train, and that they tell him to return to his own train as it is about to start; that five whistles in succession announce a wreck and command the immediate attendance of the wreck crew. In the town many cheeks blanch when those five long, ominous wails of the escaping steam cleave the air. A husband, a son, a father who has gone forth blithely in the morning, with his dinner-pail full, may be brought out of the wreck, mangled or dead. And until complete details are known there is a tremor in the whole community. Some hearts beat faster, others seem to stand still. People speak in hushed tones. One afternoon, the engineer's wife, observing the altitude of the sun, looked at the clock and saw that the time was a few minutes before five. Tom's whistle had not yet blown. At five-fifteen came the sound of another whistle. It was prolonged and then repeated. The engineer's wife stood still and counted. Five! The most docile and apparently cheerful patient in the ---- Asylum for the Insane is a widow, still young, who spends the greater time of each day sewing and humming tunes softly to herself. Every afternoon at about half-past four she assumes a listening attitude, suddenly hears an inaudible whistle, smiles tenderly, starts up and places invisible dishes and impalpable viands upon an imaginary table, and then loses herself in a reverie which ends in slumber. No striking clock is allowed within her hearing. It was long ago noticed that the stroke of five or any series of five similar sounds would cause her to moan piteously. The people afar in the country town do not laugh now when they talk of Tom and the whistle which was shrieking madly as he and his engine plunged down the bank together on that day when the huge boulder rolled from the hillside stone quarry and lay upon the tracks, just on this side of the curve above the town.
