"Ah, if Dick were only here," Jack groaned, "we could go to the square and lead away enough staff or orderly horses to serve the purpose. The little wretch! It would serve him properly to leave him here mooning over his sweetheart." Then his heart took up a little tremor of protest. He sighed gently. He, too, had loitered when his heart pleaded. Why should Dick be firmer than he? It was after midnight when he reached the sheltering, broken, ground along the river. The provost prison fronted the water. It had been a tobacco warehouse, built long before, and hastily transformed into its present military purpose. It was set in what was called a "cut" in the heavy clay bank, thus bringing the lower windows below the level of the surrounding land. There were sentries stationed in front and rear, who walked at regular intervals from corner to corner. The sentinel on the high level to the rear could not see the ground along the wall, and it was this fact which Jack calculated upon to enable him to help the prisoners to remove the _débris_ of the wall through which they were to presently emerge. The night was pitchy dark. This had been taken into consideration long before. Heavy clouds hung over the river, throwing the prison and its environs into still more security for Jack's purpose. He reconnoitred every available point, searched every corner of possible danger, and as the time passed he began to rage with impatience against Dick, whose delay was now periling the success of the enterprise. It was twelve o'clock and after. He dared wait no longer. Dick must shift for himself. Perhaps he had lost his way. In any event it was safer to set the general prisoners free, as they were only carelessly guarded. Lamps glimmered fitfully in the guard-room, throwing fantastic banners of light almost to the water's edge. He made a final tour about the broken ground, but there was no sound or suspicion of Dick. He knew every inch of the ground. Dick and he had surveyed and resurveyed it for days. The coast was clear. No one was on guard at the vital point, but still he lingered, his breath coming and going painfully, as a break in the clouds cast a moving shape over the undulating ground. Should he give the boy another half-hour's grace? He makes a circuit in the direction Dick must approach by and waits. He will count a hundred very slowly, then wait no longer. He counts up to fifty, hears a coming step, and waits alertly. No--it passes on. He begins again--counts one hundred, two hundred. No sign. "Pah! it is madness to delay for him. The young poltroon has lost his resolution in his lovesick fever. Very likely he has been unable to run the risk of Rosa's anger--her mother's indignation--the possibility of never seeing the girl again." Well, he had given him ample grace. He had endangered his own and other lives to humor a boyish whim. Now he must act, and swiftly.
