It is rather a severe reflection on the courts of justice of that period, or we might rather say, perhaps, a striking illustration of the madness that had seized on all, that although the law strictly forbade any slave to testify in a court of justice against a white person, yet this girl Mary Burton was not only allowed to appear as evidence against Peggy, but her oath was permitted to outweigh hers, and cause her to be sentenced to death. The latter, though an abandoned, desperate character, was seized with terror at the near approach of death, and begged to be allowed another examination, which was granted, and she professed to make a full confession. It is a little singular that while she corroborated Mary Burton's statement as to the existence of a conspiracy, she located the seat of it not in Hughson's tavern, but in a miserable shanty near the Battery, kept by John Romme, who, she said, had promised to carry them all to a new country, and give them their liberty, if they would murder the whites and bring him the plunder. Like Mary Burton's confession, if truthful at all, it evidently had a large mixture of falsehood in it.

On Saturday, May 9th, Peggy was again brought in, and underwent a searching examination. Some of her statements seemed improbable, and they therefore tested them in every possible way. It lasted for several hours, and resulted in a long detailed confession, in which she asserted, among other things, that it was the same plot that failed in 1712, when the negroes designed to kill all the whites, in fact, exterminate them from the island. She implicated a great many negroes in the conspiracy; and every one that she accused, as they were brought before her, she identified as being present at the meetings of the conspirators in Romme's house. The court seemed anxious to avoid any collusion between the prisoners, and therefore kept them apart, so that each story should rest on its own basis. By this course they thought they would be able to distinguish what was true and what was false.

Either from conscious guilt, or from having got some inkling of the charge to be brought against him, Romme fled before he could be arrested. His wife, however, and the negroes whose names Peggy gave, were sent to jail.

On the 11th of May, or twenty days after the court convened, the executions commenced. On this day, Caesar and Prince, two of the three negroes Mary Burton testified against, were hung, though not for the conspiracy, but for theft. They were abandoned men, and died recklessly. Peggy and Hughson and his wife were next condemned. The former, finding that her confession did not, as had been promised, secure her pardon, retracted all she had said, and exculpated entirely the parties whose arrest she had caused.

An atmosphere of gloom now rested over the city; every face showed signs of dread. In this state of feeling the Lieutenant-governor issued a proclamation, appointing a day of fasting and humiliation, not only in view of this calamity, but on account also of the want and loss caused by the past severe winter, and the declaration of war by England against Spain. When the day arrived, every shop was closed and business of all kinds suspended, and the silence and repose of the Sabbath rested on the entire community. Without regard to sect, all repaired to the places of worship, where the services were performed amid the deepest solemnity.

The day of execution appointed for Hughson, his wife, and Peggy was a solemn one, and almost the entire population turned out to witness it. The former had declared that some extraordinary appearance would take place at his execution, and every one gazed on him as he passed in a cart from the prison to the gallows. He was a tall, powerful man, being six feet high. He stood erect in the cart all the way, his piercing eye fixed steadily on the distance, and his right hand raised high as his fetters would permit, and beckoning as though he saw help coming from afar. His face was usually pale and colorless, but to-day it was noticed that two bright red spots burned on either cheek, which added to the mystery with which the superstitious spectators invested him. When the sad procession arrived at the place of execution, the prisoners were helped to the ground, and stood exposed to the gaze of the crowd. Hughson was firm and self-possessed; but Peggy, pale, and weeping, and terror-struck, begging for life; while the wife, with the rope round her neck, leaned against a tree, silent and composed, but colorless as marble. One after another they were launched into eternity, and the crowd, solemn and thoughtful, turned their steps homeward.

Hughson was hung in chains; and in a few days a negro was placed beside him, and here they swung, "blind and blackening," in the April air, in full view of the tranquil bay, a ghastly spectacle to the fishermen as they plied their vocation near by. For three weeks they dangled here in sunshine and storm, a terror to the passers-by. At length a rumor passed through the town that Hughson had turned into a negro, and the negro into a white man. This was a new mystery, and day after day crowds would come and gaze on the strange transformation, some thinking it supernatural, and others trying to give an explanation. Hughson had threatened to take poison, and it was thought by many that he had, and it was the effect of this that had wrought the change in his appearance. For ten days the Battery was thronged with spectators, gazing on these bloated, decomposing bodies, many in their superstitious fears expecting some new transformation. Under the increasing heat of the sun, they soon began to drip, till at last the body of Hughson burst asunder, filling the air with such an intolerable stench that the fishermen shunned the locality.

As simple hanging was soon thought not sufficient punishment, and they were left to swing, and slowly rot in chains, so this last was at length thought to be too lenient, and the convicts were condemned to be burned at the stake. Two negroes, named Quack and Cuffee, were the first doomed to this horrible death. The announcement of this sentence created the greatest excitement. It was a new thing to the colonists, this mode of torture being appropriated by the savages for prisoners taken in war. Curious crowds gathered to see the stake erected, or stare at the loads of wood as they passed along the street, and were unloaded at its base. It was a strange spectacle to behold—the workmen carefully piling up the fagots under the spring sun; the spectators looking on, some horrified, and others fierce as savages; and over all the blue sky bending, while the gentle wind stole up from the bay and whispered in the tree-tops overhead. On the day of execution an immense crowd assembled. The two negroes were brought forward, pale and terrified, and bound to the stake. As the men approached with the fire to kindle the pile, they shrieked out in terror, confessed the conspiracy, and promised, if released, to tell all about it. They were at once taken down. This was the signal for an outbreak, and shouts of "burn 'em, burn 'em" burst from the multitude. Mr. Moore then asked the sheriff to delay execution till he could see the Governor and get a reprieve. He hurried off, and soon returned with a conditional one. But, as he met the sheriff on the common, the latter told him that it would be impossible to take the criminals through the crowd without a strong guard, and before that could arrive, they would be murdered by the exasperated populace. They were then tied up again, and the torch applied. The flames arose around the unhappy victims. The curling smoke soon hid their dusky forms from view, while their shrieks and cries for mercy grew fainter and fainter, as the fierce fire shrivelled up their forms, till at last nothing but the crackling of the flames was heard, and the shouting, savage crowd grew still. As the fire subsided, the two wretched creatures, crisped to a cinder, remained to tell, for the hundredth time, to what barbarous deeds terror and passion may lead men.

Some of the negroes went laughing to the place of execution, indulging in all sorts of buffoonery to the last, and mocking the crowd which surrounded them.

All protested their innocence to the last, and if they had confessed previously, retracted before death their statements and accusations. But this contradiction of themselves, to-morrow denying what to-day they had solemnly sworn on the Bible to be true, instead of causing the authorities to hesitate, and consider how much terror and the hope of pardon had to do with it, convinced them still more of the strength and dangerous nature of the conspiracy, and they went to work with a determination and recklessness which made that summer the bloodiest and most terrific in the annals of New York. No lawyer was found bold enough to step forward and defend these poor wretches, but all volunteered their services to aid the Government in bringing them to punishment. The weeks now, as they rolled on, were freighted with terror and death, and stamped with scenes that made the blood run cold. This little town, on the southern part of Manhattan Island was wholly given to panic, and a nameless dread of some mysterious, awful fate, extended even to the scattered farm-houses near Canal Street. Between this and the last of August, a hundred and fifty-four negroes, exclusive of whites, were thrown into prison, till every cell was crowded and packed to suffocation with them. For three months, sentence of condemnation was on an average of one a day. The last execution was that of a Catholic priest, or rather of a schoolmaster of the city, who was charged with being one. Mary Burton, after an interval of three months, pretended to remember that he was present with the other conspirators she had first named as being in Hughson's tavern.
