I have not read all the volumes of “The Library of Christian Knowledge,” but what I have read, and especially what I know of their able and pious editor, and of his writings, make me confident in saying that the series which he is engaged in publishing, will prove a valuable addition to the religious literature of the country. We need a multiplication of such men as Mr. Hooker, and of such works as he writes and publishes; and this need should lead us to receive most thankfully, and improve most faithfully, so far as it shall extend the rich supply which he is furnishing. Very respectfully, your friend, JOHN I. STONE, _Rector of St. Paul’s Church, Boston_. _March 27th, 1837._ _Philadelphia, March 31, 1837._ MESSRS. WM. MARSHALL & CO. GENTLEMEN:--Few men exert a more decided, extensive, and lasting influence upon society than Booksellers; and in these times, when so many prostitute the press to gratify and increase the appetite for books that are worthless, or decidedly immoral in their tendency; it is exceedingly gratifying to find here a firm, who bring nothing before the world which can injure their race. So far as I have noticed, you have as yet published nothing at which you need blush, should you meet the book on the parlour table of your best friend. Among others of your productions, I have read your “Library of Christian Knowledge,” edited by Mr. Hooker. Ever since I read the little work of Mr. H. entitled “The Portion of the Soul,” I have felt sure, that he was safe; by which I mean, that any work to which he might prefix his name, would be a sound, discreet, judicious book. His taste is correct, discriminating; and his own pen at times, is guided by a hand of no ordinary strength. Honestly attached to the Episcopal Church, he, nevertheless, is so endowed with the limbs of a man, and the heart of a Christian, that his denominational habits do not hinder him from appearing in a _working dress_, in the vineyard of his Master. I can sincerely recommend the “Library,” as containing such works of practical piety, as will be useful in every family, and I could wish that the circulation of such works might banish the light reading of the age. I hope your circulation will be very extensive. Respectfully yours, J. TODD. * * * * * THE LIBRARY OF CHRISTIAN KNOWLEDGE. Edited by the Rev. Herman Hooker, A. M.
