Special Message

To the Senate and House of Representatives:

I desire to call the attention of Congress to the importance of providing for the continuance of the board for testing iron, steel, and other metals, which by the sundry civil appropriation act of last year was ordered to be discontinued at the end of the present fiscal year. This board, consisting of engineers and other scientific experts from the Army, the Navy, and from civil life (all of whom, except the secretary, give their time and labors to this object without compensation), was organized by authority of Congress in the spring of 1875, and immediately drafted a comprehensive plan for its investigations and contracted for a testing machine of 400 tons capacity, which would enable it to properly conduct the experiments. Meanwhile the subcommittees of the board have devoted their time to such experiments as could be made with the smaller testing machines already available. This large machine is just now completed and ready for erection at the Watertown Arsenal, and the real labors of the board are therefore just about to be commenced. If the board is to be discontinued at the end of the present fiscal year, the money already appropriated and the services of the gentlemen who have given so much time to the subject will be unproductive of any results.

The importance of these experiments can hardly be overestimated when we consider the almost endless variety of purposes for which iron and steel are employed in this country and the many thousands of lives which daily depend on the soundness of iron structures. I need hardly refer to the recent disaster at the Ashtabula bridge, in Ohio, and the conflicting theories of experts as to the cause of it, as an instance of what might have been averted by a more thorough knowledge of the properties of iron and the best modes of construction. These experiments can not properly be conducted by private firms, not only on account of the expense, but because the results must rest upon the authority of disinterested persons. They must therefore be undertaken under the sanction of the Government. Compared with their great value to the industrial interests of the country, the expense is very slight.

The board recommend an appropriation of $40,000 for the next fiscal year, and I earnestly commend their request to the favorable consideration of Congress. I also recommend that the board be required to conduct their investigations under the direction of the Secretary of War, and to make full report of their progress to that officer in time to be incorporated in his annual report.

U.S. GRANT.
