investigations of the Department of Labor, and the like, which I must have to give correctness and precision to my instruction in matters of State and Federal administration. Then they are indispensable for reference. I am constantly having trouble in remembering whether the pension bureau is a bureau or a division, or is in the War Department, where it would seem to belong, or in the Department of Commerce and Labor, or somewhere else. It really does not matter so much, for doubtless most of our best citizens do not know where it is, especially since, under our system of indirect taxation, they don’t feel its hands in their pockets. Finally, there are Supreme Court decisions. Here laymen must beware, for the lawyers have forbidden us to come in; only one who has mastered the mysteries of real property and torts, so they would have us believe, can understand the mysteries of direct taxation as defined by the Supreme Court of the United States. Now, we must not take the lawyers too seriously, but we must master the elements of law and also learn how to get the “point” of a case, discover the facts and separate the necessary reasoning from the _obiter_. Certainly, no student of American government has any business teaching the subject unless he has read and understood many of the greatest decisions of the august tribunal that presides over our political destinies. III. A third group of materials embraces State and Federal laws. How many readers of this article have ever seen in one spot the yearly output of his State legislature or Congress? How many readers who have discussed Congressional appropriations have ever seen an appropriation bill or part of one? How many readers who have discussed tariff and finance have ever seen a real live tariff bill reposing in the pages of the statutes of the United States? I always take Ash’s edition of the charter of New York City--a portly volume of about a thousand pages--into my class room and perform before the eyes of the students the experiment of running through the chief titles. It helps to keep them modest in their estimate of their knowledge of our city government, and it is a standing apology for the innumerable question which I fail to answer. I may mention, also, in leaving this group, the State election law which can be secured readily from the Secretary of the Commonwealth, and should be always in hand.
