A superb work and one of the very earliest arguing explicitly, on the grounds of Christianity, for the immediate abolition of the slave trade. Hersey was a Methodist divine who was friends with the famous Liberian missionary, Melville Cox, himself traveled to and preached in the Liberian colony, was an advocate for Native American rights, etc., His own ministry was largely in Baltimore, where he traveled as a home missionary and worked both in white and "negro" communities of the enslaved.

Scarce. No first editions in the auction record or trade. The second edition, as here, but once at auction and none in the trade as of the time of cataloging.
