The third class of cases relates to the violation of those sections which aim to protect training and mobilization camps from the evil influence of the liquor traffic or prostitution within the neighborhood of the camp. The first class of cases has thrown upon the representatives of this department throughout the country an immense amount of work. This work has consisted in part of prosecuting deliberate violations of the law. In far larger measure, however, it has consisted in locating, apprehending, and delivering to local boards or Army officials many thousands of men who for various reasons have failed to appear for physical examination, failed to file questionnaires, etc. _Down to July 1, 1918, the department had thus investigated 220,747 cases of this character and caused induction into military service of 23,439 men._ A curious personal quality attaches to the study of the work of the American Protective League, which is perhaps attributable to the fact that all the members were amateurs only and altogether unpaid. No doubt, did space and formal limitations permit, a very widespread comment on the personal relations of the members of the League to the League itself would be acceptable to many readers. Within the limits available, however, a certain martial severity and impersonality must be employed. None the less, there ought to be some brief mention made of the work of the National Directors after the establishment of the Washington office. In this connection it is fitting that the names of those men should be mentioned who labored so earnestly and so well to make the work of A. P. L. of vital importance in the winning of the war.
