Autograph letter signed : Burlington [NJ], to Mr. Gales, 1853 May 5.

Sending Gales a copy of his book The slave trade, domestic and foreign: why it exists and how it may be extinguished; writing "The subject is an important one, and you will find that I have brought together many important facts that are little known. -- The people of the south ought to read it, for it is the best defence that can be offered for them, while it tends to shew them how they can profitably to themselves settle their account with a nation that is, of all others, the most abusive of them -- Read it --".
