Prof. Laughlin has just published a little volume containing a compilation of the United States Laws relating to American Shipping. It is primarily for the use of the students in Political Economy 3, but the convenient form in which these laws have been gathered together and arranged will make the book of great value to all who are interested in subjects connected with political science. The labor of searching for many hours, through the innumerable pages that make up the Statutes at Large, for any particular law is, by means of Prof. Laughlin's work, very much reduced. The remarks that follow each extract are well to the point, and show, in general, the relation of the law in question to those that have preceded it. We congratulate all political economy students on the material aid that has been rendered them by this work of Prof. Laughlin.
