New York papers have been received to the 17th of
July. They contain accounts of some serious riots which occurred in that city on the 9th, 10th, and 11th of last month. It seems that much excitement has prevailed among the least reputable of the White inhabitants, in consequence of the efforts of the Anti-Slavery Society to procure the emancipation of the Negroes in the slaveholding states. A trivial circumstance irritated the people on the evening of the 9th. A number of Blacks had assembled in a chapel for the celebration of the 4th of July, the anniversary of American independence; a ceremony which they had for some reason, deferred for a few days. A society of Singers also intended to meet at the same chapel ; but they found it preoccupied, and were much enraged at the insolence of the Negroes. A crowd soon collected and attacked the poor Blacks ; and thence they proceeded to break the windows of several unpopular individuals, as well as demolishing the interior of four churches and chapels where anti-slavery doctrines were preached. The police and the military at length succeeded in suppressing the riots ; which, however, continued during the greater part of three days. It is impossible to give any distinct account of what occurred on each of the days, owing to the imperfect manner in which the American papers have detailed the events. Similar outrages took place about the same time in some places in Connecticut and New Jersey.
