Experience of the difficulties attending the determination of our admitted line of boundary, after the occupation of the territory and its settlement by those owing allegiance to the respective Governments, points to the importance of establishing, by natural objects or other monuments, the actual line between the territory acquired by purchase from Russia and the adjoining possessions of Her Britannic Majesty. The region is now so sparsely occupied that no conflicting interests of individuals or of jurisdiction are likely to interfere to the delay or embarrassment of the actual location of the line. If deferred until population shall enter and occupy the territory, some trivial contest of neighbors may again array the two Governments in antagonism. I therefore recommend the appointment of a commission, to act jointly with one that may be appointed on the part of Great Britain, to determine the line between our Territory of Alaska and the conterminous possessions of Great Britain.

In my last annual message I recommended the legislation necessary on the part of the United States to bring into operation the articles of the treaty of Washington of May 8, 1871, relating to the fisheries and to other matters touching the relations of the United States toward the British North American possessions, to become operative so soon as the proper legislation should be had on the part of Great Britain and its possessions.

That legislation on the part of Great Britain and its possessions had not then been had, and during the session of Congress a question was raised which for the time raised a doubt whether any action by Congress in the direction indicated would become important. This question has since been disposed of, and I have received notice that the Imperial Parliament and the legislatures of the provincial governments have passed laws to carry the provisions of the treaty on the matters referred to into operation. I therefore recommend your early adoption of the legislation in the same direction necessary on the part of this Government.

The joint commission for determining the boundary line between the United States and the British possessions between the Lake of the Woods and the Rocky Mountains has organized and entered upon its work. It is desirable that the force be increased, in order that the completion of the survey and determination of the line may be the sooner attained. To this end I recommend that a sufficient appropriation be made.

With France, our earliest ally; Russia, the constant and steady friend of the United States; Germany, with whose Government and people we have so many causes of friendship and so many common sympathies, and the other powers of Europe, our relations are maintained on the most friendly terms.

Since my last annual message the exchange has been made of the ratifications of a treaty with the Austro-Hungarian Empire relating to naturalization; also of a treaty with the German Empire respecting consuls and trade-marks; also of a treaty with Sweden and Norway relating to naturalization; all of which treaties have been duly proclaimed.

Congress at its last session having made an appropriation to defray the expense of commissioners on the part of the United States to the International Statistical Congress at St. Petersburg, the persons appointed in that character proceeded to their destination and attended the sessions of the congress. Their report shall in due season be laid before you. This congress meets at intervals of about three years, and has held its sessions in several of the countries of Europe. I submit to your consideration the propriety of extending an invitation to the congress to hold its next meeting in the United States. The Centennial Celebration to be held in 1876 would afford an appropriate occasion for such meeting.

Preparations are making for the international exposition to be held during the next year in Vienna, on a scale of very great magnitude. The tendency of these expositions is in the direction of advanced civilization, and of the elevation of industry and of labor, and of the increase of human happiness, as well as of greater intercourse and good will between nations. As this exposition is to be the first which will have been held in eastern Europe, it is believed that American inventors and manufacturers will be ready to avail themselves of the opportunity for the presentation of their productions if encouraged by proper aid and protection.

At the last session of Congress authority was given for the appointment of one or more agents to represent this Government at the exposition. The authority thus given has been exercised, but, in the absence of any appropriation, there is danger that the important benefits which the occasion offers will in a large degree be lost to citizens of the United States. I commend the subject strongly to your consideration, and recommend that an adequate appropriation be made for the purpose.

To further aid American exhibitors at the Vienna Exposition, I would recommend, in addition to an appropriation of money, that the Secretary of the Navy be authorized to fit up two naval vessels to transport between our Atlantic cities and Trieste, or the most convenient port to Vienna, and back, their articles for exhibition.
