“. . . I have sent for yourself the Library of Useful Knowledge, as far as published: with the Farmers’ Series and Maps. The Entertaining Knowledge Library is for the younkers (tho’ good and wholesome for all ages). . . . I believe we begin with 15,000 and print to above 20,000. Now pray, if any subject falling in with our plans occurs to you, suggest it. You will do us a real service. We profess to be able to prepare and put in circulation to a vast extent any work of useful tendency and sound principles. Of course we avoid direct part in Church and State, but we openly profess to preach peace, liberty and absolute toleration, and I take care, as the works pass through my hands, to keep out all that is against these principles, and to put in authoritatively what is wanting upon them. . . .”
