As editor of the “Library of Christian Knowledge,” it is difficult to conceive of one better qualified in all respects, than the Rev. Mr. Hooker. Remarkable for his mental discipline; familiar with our literature, and especially with the higher order of Theological Letters; habitually conversant with principles of human nature, and embracing in his wishes to benefit others, all sensible and good men, he has rendered a most acceptable service to your readers, and secured an enviable distinction to himself. The selected works so far are, in my judgment, most excellent. “M’Laurin’s Essays” can never be depreciated but by such as have no sympathy with intellectual elevation and manly piety. “Goode’s Better Covenant” has already passed to the second edition; and few men of intelligence, but must admire its chaste, simple and manly style; and its clear discrimination and affecting views of Christian doctrines and Christian duties. “Russell’s Letters,” comprising No. 3 and 4, are of far more extensive application than their title imports. No person of reflection, whether he be a religious man or not, can fail of finding both interest and profit in the reading. No. 5, Mr. Hooker’s original work, has been so recently published, and so extensively spoken well of, that I will say only, that if a man desires the best of company, in which he will find what will please and improve and dignify, during his reading hours, let him discourse with “Hooker’s Popular Infidelity.” Yours, very respectfully, CHARLES HENRY ALDEN. _Feb. 20, 1837._ _Baltimore, Feb. 15, 1837._ MESSRS. WM. MARSHALL & CO. GENTLEMEN:--In answer to yours of the 4th inst. it gives me pleasure to state, that I have read the volumes of the “Library of Christian Knowledge,” already published, and am gratified that evangelical works of such distinguished merit have been offered to the reading community in a form so popular and attractive. You have done well, I think, in securing the editorial services of the talented author of “The Portion of the Soul,” and “Popular Infidelity,” whose well known taste and established orthodoxy, give assurance that he will select no works, that will not be worthy of perusal, and well adapted to the peculiar wants of the church, at this interesting period. I am happy to find, that you design to continue the publication of the Library, and sincerely hope that you will be sustained in it by the liberal patronage of the Christian public. Yours, respectfully, J. P. K. HENSHAW, D. D. _Philadelphia, March 13th, 1837._ MESSRS. WM. MARSHALL & CO.
