Albany, April 11, 1848.

Mr. F. Douglass—My Dear Sir: — You will pardon the liberty I am taking in addressing you these few lines, in proportion to the importance of the subject they involve.—You doubtless recollect a young man residing in this city by the name of John S. Brown, a Virginian by birth, and who had been a portion of last summer or fall under the direction of the friends of human rights in Boston, and I believe also in the town of Lynn, under the protection of Mr. Buffum and others, and has, since that time, been engaged in lecturing about the country. He having left home, with the intention of returning in three or four weeks, about the 1st of February, and his not having written or returned to this date, there is great apprehension felt for his safety by us all, and more so by his afflicted wife and child. Should you, therefore, be in the possession of any information relative to his whereabouts, you will confer a favor not only upon his wife, but your obliged and humble servant.

John G. STEWART.

Any information respecting John S. Brown, will be thankfully received at this office.
