THE author would have preferred writing no preface whatever to this little book, were it not indispensably necessary, in order to meet the erroneous views some men entertain in regard to works of this character. The majority, undoubtedly, approve of the publication and sale of such books, yet some are always found who will persist in denouncing them as something wrong. This latter class I cannot help but pity, for being so far led astray; and I earnestly pray everyone who might find it in his power, to bring them from off their ways of error.
