NEW HAVEN, Sept. 10th, 1855.

MR. EDITOR:—The subject of slavery—and the question: What has the North to do with it? has been pressed home upon many in this community, within a few days, with great earnestness.

1st. Capt. DANIEL DRAYTON, of the Schooner Pearl enterprise of 1848, has been here with his narrative [illegible]. On the evening of the 2d inst., he [illegible] in the Temple St. Church to a very [illegible], for an hour and a half, in which he gave a history of that affair, and of his experience when in the hands of slaveholders, and in the prison at the nation's capital. He seems an honest and faithful man, and may this little notice open some other door for him, and let the friends of the slave help him and encourage him wherever he may go, on his mission of love.

2d. While we were engaged with him, we were called upon, by a friend, to go and see the conductor of one of the Underground Railroads, who had just arrived with some passengers from Alabama, the particulars of which may not be stated, at the present time, for the route must be traveled over again, e're long, to bring those who are left behind. We only wish to assure the friends, that those who have arrived are well, and have the prospect of doing well.

They speak, in praise, of the road, and of the faithfulness of the conductor. A large number of friends greeted them yesterday in the Temple St. Church, and tendered to them sympathy and "material aid," and assured them, that if they had left the sunny South to have the inclemency of a Northern climate, for freedom's sake, that they would find that genial , which cannot be found in the land of fetters and chains.
