In the absence of definite training and knowledge to furnish a basis for examination the diplomatic service is either exceptionally fortunate or exceptionally unfortunate. As long as the good of the service is kept chiefly in view in the selection of candidates, even though the service be regarded as political, it is well that technical knowledge cannot interfere seriously with the appointment of the most promising candidate. On the other hand, when the service is regarded as a legitimate means of rewarding political friends it will suffer all the more for the want of a restraint such as the examination affords, just as with the consular service, only in a greater degree. Diplomatic officers are more apt to change with the change of administration than are consular officers, for the reason that the service itself is more political in character. Some authorities go so far as to justify the change on the ground that the administration ought to be unrestricted in carrying out its policy, and therefore should be represented abroad by those of its own political faith just as it is in the cabinet. It must be admitted that there is a great deal to justify this contention, but it should be said that the analogy with the President’s cabinet is hardly fair; for in the latter case the parties are the units, and we recognize the right of the stronger party to full executive power; but in the case of the ambassadors the nation is the unit which he represents, not the party. Theoretically the change of diplomatic officials with the change of administration cannot be justified, and practically a sweeping change is certainly demoralizing to our interests. In the most important positions, however, it may sometimes be best that the President be allowed to substitute those of his own party. With the present system of recruiting the diplomatic service the most essential point is to lodge the testing power in the hands of capable and incorruptible men, so that those who are “appointed for examination” will not necessarily pass because of the influence which supports them. I will now leave the subject with you, merely remarking in closing that diplomacy, especially American diplomacy, which lies outside of and beyond our present theme, is of fascinating interest and will well repay careful study. Our diplomatic history is brief, but it is glorious, chiefly because it has made for righteousness and peace, not to ourselves only but to all the world. * * * * * “Professor, will you kindly give the remainder of the articles of the Congress of Vienna”? “Certainly. Besides the first and the last which have already been given, they are as follows: “Art. II.
