To know that in the woods the brooks were singing over pebbly bottoms, that in the fields the air was filled with the fragrance of blossoming flowers, that everywhere the free wind rioted at will, and then to sit in such a prison-house as this all day, and breathe an atmosphere so thick with dust that even the bits of blue sky framed in by the open windows in the summer time were like strips of some dark thunder-cloud,--it was this, this dull monotony of dizzy sight and doleful sound and changeless post of duty, that made their task a hard one. There came a certain summer day at Burnham Breaker when the labor and confinement fell with double weight upon the slate-pickers in the screen-room. It was circus day. The dead-walls and bill-boards of the city had been gorgeous for weeks and weeks with pictures heralding the wonders of the coming show. By the turnpike road, not forty rods from where the breaker stood, there was a wide barn the whole side of which had been covered with brightly colored prints of beasts and birds, of long processions, of men turning marvellous somersaults, of ladies riding, poised on one foot, on the backs of flying horses, of a hundred other things to charm the eyes and rouse anticipation in the breasts of boys. Every day, when the whistle blew at noon, the boys ran, shouting, from the breaker, and hurried, with their dinner-pails, to the roadside barn, to eat and gaze alternately, and discuss the pictured wonders. And now it was all here; beasts, birds, vaulting men, flying women, racing horses and all. They had seen the great white tents gleaming in the sunlight up in the open fields, a mile away, and had heard the distant music of the band and caught glimpses of the long procession as it wound through the city streets below them. This was at the noon hour, while they were waiting for the signal that should call them back into the dust and din of the screen-room, where they might dream, indeed, of circus joys while bending to their tasks, but that was all. There was much wishing and longing. There was some murmuring. There was even a rash suggestion from one boy that they should go, in spite of the breaker and the bosses, and revel for a good half-day in the pleasures of the show. But this treasonable proposition was frowned down without delay. These boys had caught the spirit of loyalty from the men who worked at Burnham Breaker, and not even so great a temptation as this could keep them from the path of duty. When the bell rang for them to return to work, not one was missing, each bench had its accustomed occupant, and the coal that was poured into the cars at the loading-place was never more free from slate and stone than it was that afternoon.
