The Book of Trade Secrets. By an Expert. (T. Haslam

and Co. is. net.)—The title has an attractive sound. We should learn here how to do things which we commonly get done for us, at more or less cost, by others. "Old Books and Papers" are the special subjects of instruction. Nor do we doubt for a moment that some excellent advice is given in these pages, and some very effective methods described. But there is a great gap between knowing what we ought to do and doing it. Ho would be a rash person who should try his prentice hand on any valuable book or paper. With this caution this little book, which is conveniently arranged in alphabetical order, may be recommended.
