On the 24th of April, Cæsar Varick, Prince Auboyman, John Hughson, his wife, and Peggy Carey were arraigned for felony, and pleaded not guilty. Cæsar and Prince were first put on trial. As they did not challenge the jury, the following gentlemen were sworn: Messrs. Roger French, John Groesbeck, John Richard, Abraham Kipp, George Witts, John Thurman, Patrick Jackson, Benjamin Moore, William Hammersley, John Lashiere, Joshua Sleydall, and John Shurmer. "Guilty!" as charged in the indictment. They had committed the robbery, so said the jury.

On the 3d of May one Arthur Price, a common thief, was committed to jail for theft. He occupied a cell next to the notorious Peggy Carey. In order to bring himself into favor with the judges, he claimed to have had a conversation with Peggy through the hole in the door. Price says she told him that "she was afraid of those fellows" (the Negroes); that if they said any thing in any way involving her she would hang every one of them; that she did not care to go on the stand again unless she was called; that when asked if she intended to set the town on fire she said no; but she knew about the plot; that Hughson and his wife "were sworn with the rest;" that she was not afraid of "Prince, Cuff, Cæsar, and Fork's Negro—not Cæsar, but another," because they "were all true-hearted fellows." This remarkable conversation was flavored throughout with the vilest species of profanity. Notwithstanding this interview was between a common Irish prostitute and a wretched sneak-thief, it had great weight with the solemn and upright judges.

In the midst of this trial, seven barns were burnt in the town of Hackinsack. Two Negroes were suspected of the crime, but there was not the slightest evidence that they were guilty. But one of them said that he had discharged a gun at the party who set his master's barn on fire, but did not kill any one. The other one was found loading a gun with two bullets. This was enough to convict. They were burnt alive at a stake. This only added fuel to the flame of public excitement in New York.

On the 6th of May (Wednesday) two more arrests were made,—Hughson's daughter Sarah, suspected of being a confederate, and Mr. Sleydall's Negro Jack,—on suspicion of having put fire to Mr. Murray's haystack. On the same day the judges arraigned the white persons implicated in the case,—John Hughson, his wife, and Peggy Carey. The jury promptly found them guilty of "receiving stolen goods." "Peggy Carey," says Recorder Horsemanden, "seeming to think it high time to do something to recommend herself to mercy, made a voluntary confession." This vile, foul-mouthed prostitute takes the stand, and gives a new turn to the entire affair. She removes the scene of the conspiracy to another tavern near the new Battery, where John Romme had made a habit of entertaining, contrary to law, Negro slaves. Peggy had seen many meetings at this place, particularly in December, 1740. At that time she mentioned the following Negroes as being present: Cuff, Brash, Curacoa, Cæsar, Patrick, Jack, Cato; but her especial Cæsar Varick was not implicated! Romme administered an oath to all these Negroes, and then made a proposition to them; viz., that they should destroy the fort, burn the town, and bring the spoils to him. He engaged to divide with them, and take them to a new country, where he would give them their freedom. Mrs. Romme was present during this conversation; and, after the Negroes had departed, she and the deponent (Peggy) were sworn by Romme to eternal secrecy. Mrs. Romme denied swearing to the conspiracy, but acknowledged that her husband had received stolen goods, that he sold drams to Negroes who kept game-fowls there; but that never more than three Negroes came at a time. She absconded in great fright. It has been mentioned that Peggy Carey had lived at the tavern of John Romme for a short time, and that articles belonging to Mr. Hogg had been found under the kitchen floor of the house next to Romme's.

The judges evidently reasoned that all Negroes would steal, or that stealing was incident upon or implied by the condition of the slave. Then Romme kept a "tippling-house," and defied the law by selling "drams" to Negroes. Now, a man who keeps a "tippling-house" was liable to encourage a conspiracy.

A full list of the names of the persons implicated by Peggy was handed to the proper officers, and those wicked persons apprehended. They were brought before the redoubtable Peggy for identification. She accused them of being sworn conspirators. They all denied the charge. Then they were turned over to Mary Burton; and she, evidently displeased at Peggy's attempt to rival her in the favor of the powerful judges, testified that she knew them not. But it was vain. Peggy had the ear of the court, and the terror-stricken company was locked up in the jail. Alarmed at their helpless situation, the ignorant Negroes began "to accuse one another, as it would seem, by way of injuring an enemy and guarding themselves."

Cæsar and Prince, having been tried and convicted of felony, were sentenced to be hanged. The record says,—

"Monday, 11th of May. Cæsar and Prince were executed this day at the gallows, according to sentence: they died very stubbornly, without confessing any thing about the conspiracy: and denied that they knew any thing about it to the last. The body of Cæsar was accordingly hung in chains."[248]

On the 13th of May, 1741, a solemn fast was observed; "because many houses and dwellings had been fired about our ears, without any discovery of the cause or occasion of them, which had put us into the utmost consternation." Excitement ran high. Instead of getting any light on the affair, the plot thickened.
