"Sir: Having published a pamphlet explaining my experience on the practice and effects of torpedoes, I beg leave to present you, and each member of the House of Representatives, one copy. Should the House consider this subject of sufficient interest to merit further explanation, I shall be happy to give a lecture at such time and place as may be most convenient, in which I will exhibit the various modes of attack with torpedoes and harpoon guns, as prepared for action, with such models and demonstrations as will lead to a clear understanding of the subject.

Navigation of the Mobile.

The following Message was received from the President of the United States:

To the House of Representatives of the United States:

I transmit to the House a report of the Secretary of State, complying with their resolution of the 22d of January.

JAMES MADISON.

February 9, 1810.

Department State, Feb. 8, 1810.

The Secretary of State, to whom the President has been pleased to refer the resolution of the House of Representatives of the 22d of last month, has the honor to state that it appears from the records in this department, that in the years 1801 and 1802, the Executive had endeavored to obtain, for the citizens of the United States residing on the waters of Tombigbee and Alabama rivers, the free navigation of the Mobile river to its confluence with the ocean—first, by claiming this navigation as a natural right, sanctioned by the general principles of the law of nations applicable to rivers similarly situated; and, secondly, by endeavoring to purchase the country held by Spain on the Mobile.

These efforts were made before it was known that Spain had ceded Louisiana to France, and consequently before the purchase of that province by the United States. Since that purchase, the country held by Spain on the Mobile has been claimed as being included therein.

The Spanish Government, having objected to this claim in a manner which justified a belief that the question would not be soon decided, our Minister at Madrid was instructed again to claim the free navigation of the Mobile under the general principles of the law of nations, and to represent to His Catholic Majesty the propriety and necessity of giving orders to his officers not to interrupt the free communication with our Territories through the waters of the Mobile.

In addition to what has been done through this department, it appears that the Governor of the Orleans Territory, and other officers of the United States, have endeavored to induce the Spanish authorities on the Mobile to abstain from exacting duties on the passage of our merchandise or produce up or down that river. Notwithstanding, however, every thing which has been done, it is understood that these authorities have continued to exact (with some occasional relaxations) a duty of twelve per cent. "on all articles of the growth or manufacture of the United States, which are conveyed through said river to and from the city of New Orleans."

All which is respectfully submitted.

R. SMITH.
