The effect was magical. The scene changed on the instant from one of quiet to one of noisy activity. Men were loosening the ruined mass with their picks, and urging their crow-bars between the blocks of stone, and shovelling the finer refuse into the carts, and loading the coarser fragments with their hands. The gang-boss, mounted upon a section of wall, began to direct the work before him. A cart had been driven among the ruins, and he called three of us to load it with the jagged masonry that lay heaped about it. It was too coarse to be handled with shovels, and we went at it with our hands. They were soon bleeding from contact with the sharp edges of rock; but the dust acted as a styptic and helped vastly in the hardening process. When the cart was loaded, another took its place, and then a third and a fourth. In a harsh, resonant voice the boss was shouting his orders over our heads, to the farthermost portion of the works. His short, thickset, muscular figure seemed rooted to the masonry on which he stood. The mingled shrewdness and brute strength of his hard face marked him as a product of natural selection for the place that he filled. His restless gray eyes were everywhere at once, and his whole personality was tense with a compelling physical energy. If the work slackened in any portion of the ruins, his voice took on a vibrant quality as he raised it to the shout of "Now, boys, at it there!" and then a lash of stinging oaths. You could feel a quickening of muscular force among the men, like the show of eager industry in a section of a school-room that has fallen suddenly under the master's questioning eye. In the dust which rose from the débris I picked up a mass of heavy plaster, and, before detecting my mistake, I tossed it into the cart. But the boss had seen the action, and instantly noticed the error, and now all his attention was directed upon me. In short, incisive sentences, ringing with malediction, he cursed me for an ignoramus and threatened me with discharge. I could feel the amused side-glances of the men, and could hear their muffled laughter. At last all the carts were loaded and driven away, and until their return, some of us were set at assorting the débris--throwing the splintered laths and bricks and fragments of stone and plaster into separate heaps. The work compelled a stooping posture, and the pain of lacerated fingers was as nothing compared with the agony of muscles cramped and forced to unaccustomed use.
