I entered a large grassy yard, surrounded by an exceedingly high wall. On the top of this wall, soldiers with muskets in their hands, were thickly planted. The yard below was broken by irregular buildings of brick. I climbed by a flight of rickety outside stairs to the central building, where many officers were seated at the windows, and looked awhile at the strange scene on the grassy plaza. On the left, the long, barred, impregnable penitentiary rose. The shady spots beneath it were occupied by huddling spectators. Soldiers were filling their canteens at the pump. A face or two looked out from the barred jail. There were many umbrellas hoisted on the ground to shelter civilians beneath them. Squads of officers and citizens lay along the narrow shadow of the walls. The north side of the yard was enclosed on three sides by columns of soldiers drawn up in regular order, the side next to the penitentiary being short to admit of ingress to the prisoner's door; but the opposite column reached entirely up to the north wall. Within this enclosed area a structure to be inhabited by neither the living nor the dead was fast approaching completion. It stood gaunt, lofty, long. Saws and hammers made dolorous music on it. Men, in their shirt sleeves, were measuring it and directing its construction in a business way. Now and then some one would ascend its airy stair to test its firmness; others crawled beneath to wedge its slim supports, or carry away the falling debris. Toward this skeleton edifice all looked with a strange nervousness. It was the thought and speculation of the gravest and the gayest. It was the gallows. A beam reached, horizontally, in the air, twenty feet from the ground; four awkward ropes, at irregular intervals, dangled from it, each noosed at the end. It was upheld by three props, one in the center and one at each end. These props came all the way to the ground where they were morticed in heavy bars. Midway of them a floor was laid, twenty by twelve feet, held in its position on the farther side by shorter props, of which there were many, and reached by fifteen creaking steps, railed on either side. But this floor had no supports on the side nearest the eye, except two temporary rods, at the foot of which two inclined beams pointed menacingly, held in poise by ropes from the gallows floor. And this floor was presently discovered to be a cheat, a trap, a pitfall. Two hinges only held it to its firmer half. These were to give way at the fatal moment, and leave only the shallow and unreliable air for the bound and smothering to tread upon. The traps were two, sustained by two different props. The nooses were on each side of the central support. Was this all? Not all. Close by the foot of the gallows four wooden boxes were piled upon each other at the edge of four newly excavated pits, the fresh earth of which was already dried and brittle in the burning noon.
