Holograph, signed.

Oliver Johnson regrets that he cannot be present at the fair and recalls his intimate association with his Boston anti-slavery friends, alluding especially to Maria Weston Chapman's magnanimity. The beautiful articles which Oliver Johnson encloses were made in Wilmington, Delaware, a slave state, by Margaret D. Gibbons, the sister of James S. Gibbons. He requests that these articles are laid on the Southwick's table. Cassius M. Clay furnished his autographs at Oliver Johnson's request. Clay will write for the Tribune. Johnson comments: "If he does not fall into the slough of Third Party, he will yet do a great work for Freedom." Maria Weston Chapman's "Prophesy" was a most welcome contribution to The Tribune; Johnson suggests that Chapman writes for this paper, which has a circulation of 45,000. Oliver Johnson is now exclusively employed in the editorial department. [Oliver Johnson was assistant to Horace Greeley on the New York Tribune from 1844 to 1848.] Johnson expresses admiration for Maria W. Chapman's Annual Report.
