A point to be noted at the outset, in any discussion of the teaching of international law to law students, is the relatively unimportant place which the subject occupies in the law student's program of study. The students in our law schools are tolerant of the interest which others manifest in international law. Indeed they are themselves greatly interested. They concede freely that it occupies an important place in the general scheme of things. But most of them feel that professional students cannot afford the time for even an introductory course. It results that courses in international law included in law school curricula are usually elected by a comparatively small group of students, while courses offered in the departments of political science and open to law students are not likely to be elected by any law students at all.
