Some thought the Spanish negroes had set the buildings on fire from revenge, especially as those of the Government were the first to suffer. Others declared that it was a plot of the entire negro population to burn down the city. This belief was strengthened by the fact that, in one of the last fires, a slave of one of the most prominent citizens was seen to leap from the window, and make off over garden fences. A shout was immediately raised by the spectators, and a pursuit commenced. The terrified fugitive made desperate efforts to escape, but being overtaken, he was seized, and, pale as death, lifted on men's shoulders and carried to jail. Added to all this, men now remembered it lacked but a few days of being the anniversary of the bloody riot of thirty years ago. They began to watch and question the negroes, and one of the Spanish sailors, on being interrogated, gave such unsatisfactory, suspicious answers, that the whole crew were arrested, and thrown into prison. But that same afternoon, while the magistrates, whom the alarming state of things had called together, were in consultation about it, the cry of "Fire!" again startled the entire community. The ringing of the alarm-bell had now become almost as terrifying as the sound of the last trumpet, and the panic became general. The first step was to ascertain if there were any strangers in town who might be concealed enemies, and a thorough search was made--the militia being ordered out, and sentries posted at the ends of all the streets, with orders to stop all persons carrying bags and bundles.

None being found, the conclusion became inevitable that some dark, mysterious plot lay at the bottom of it all, and the inhabitants thought the city was doomed, like Sodom. First, the more timorous packed up their valuable articles and fled into the country, up toward Canal Street. This increased the panic, which swelled until almost the entire population were seen hurrying through the streets, fleeing for their lives. The announcement of an approaching army would not have created a greater stampede. Every cart and vehicle that could be found was engaged at any price, into which whole families were piled, and hurried away to the farms beyond Chambers Street, in the neighborhood of Canal Street. It was a strange spectacle, and the farmers could hardly believe their senses, at this sudden inundation into their quiet houses of the people of the city. The town authorities were also swept away in the general excitement, and negroes of all ages and sexes were arrested by the wholesale, and hurried to prison. The Supreme Court was to sit in the latter part of April, and the interval of a few days was spent in efforts to get at the guilty parties. But nothing definite could be ascertained, as the conspirators, whoever they were, kept their own secret. At length, despairing of getting at the truth in any other way, the authorities offered a reward
