Holograph, signed.

Before leaving Boston, Richard Hildreth deposited with John A. Collins the stereotype plates of his books, "Archie Moore" and "Despotism in America," to be printed and sold by the Massachusetts Anti-Slavery Society. Collins sold only seventy copies in one year. Richard Hildreth, however, has 150 copies of "Archie Moore," previously printed, which he would like to have distributed among the slaveholding members of Congress. The climate of Demerara suits Hildreth, although he been ill several weeks. Hildreth has sent to Mr. Wheeler a part of his work, "Rudiments of the Inductive Science of Man," suggesting that it be handed to Caroline Weston. Hildreth discusses his theory of progress and reaction. He has sent Caroline Weston a report on the laboring population of this colony containing "decisive proof that the black population, within a very moderate period, will become the lords of the soil here." He explains the difference of status between the blacks and the mulattos, and the practice of intermarriage between the mulattos and the whites.
