The attention of Congress is again asked to the wasteful depredations committed on our public timber lands and the rapid and indiscriminate destruction of our forests. The urgent necessity for legislation to this end is now generally recognized. In view of the lawless character of the depredations committed and the disastrous consequences which will inevitably follow their continuance, legislation has again and again been recommended to arrest the evil and to preserve for the people of our Western States and Territories the timber needed for domestic and other essential uses. The report of the Director of the Geological Survey is a document of unusual interest. The consolidation of the various geological and geographical surveys and exploring enterprises, each of which has heretofore operated upon an independent plan, without concert, can not fail to be of great benefit to all those industries of the country which depend upon the development of our mineral resources. The labors of the scientific men, of recognized merit, who compose the corps of the Geological Survey, during the first season of their field operations and inquiries, appear to have been very comprehensive, and will soon be communicated to Congress in a number of volumes. The Director of the Survey recommends that the investigations carried on by his bureau, which so far have been confined to the so-called public-land States and Territories, be extended over the entire country, and that the necessary appropriation be made for this purpose. This would be particularly beneficial to the iron, coal, and other mining interests of the Mississippi Valley and of the Eastern and Southern States. The subject is commended to the careful consideration of Congress. The Secretary of the Interior asks attention to the want of room in the public buildings of the capital, now existing and in progress of construction, for the accommodation of the clerical force employed and of the public records. Necessity has compelled the renting of private buildings in different parts of the city for the location of public offices, for which a large amount of rent is annually paid, while the separation of offices belonging to the same Department impedes the transaction of current business. The Secretary suggests that the blocks surrounding Lafayette Square on the east, north, and west be purchased as the sites for new edifices for the accommodation of the Government offices, leaving the square itself intact, and that if such buildings were constructed upon a harmonious plan of architecture they would add much to the beauty of the national capital, and would, together with the Treasury and the new State, Navy, and War Department building, form one of the most imposing groups of public edifices in the world.
