"The most complete and exhaustive treatise on the wages question with which we are acquainted . . . the general correctness of its line of argument is in striking contrast to much that has been written on the subject, and especially to the similar work which in recent times has attracted most attention."—Nation.

"The subject, which is commonly reckoned dry and uninteresting, is treated in such a manner as to interest and entertain, as well as instruct the reader. The author has done a great deal of honest and conscientious work in the way of educating the people in political economy and the true principles of finance."—N. Y. Tribune.

"A real treasure house of information. . . . We do not recall the name of an author of any important contribution to the discussion of the laws of money who is not here briefly, but intelligently quoted. . . .

The work will win a very honorable place for its author among the few who are advancing towards the mastery of a most difficult science."—N. Y. Tribune.

"The book will not only interest the reader, it will set him thinking for himself."—N. Y. World.
