From all the light that has been shed on this subject I am satisfied that every favorable anticipation which has been formed of this great undertaking will be verified, and that when completed it will afford very great if not complete protection to our Atlantic frontier in the event of another war--protection sufficient to counterbalance in a single campaign with an enemy powerful at sea the expense of all these works, without taking into the estimate the saving of the lives of so many of our citizens, the protection of our towns and other property, or the tendency of such works to prevent war. Our military positions have been maintained at Belle Point, on the Arkansas, at Council Bluffs, on the Missouri, at St. Peters, on the Mississippi, and at Green Bay, on the upper Lakes. Commodious barracks have already been erected at most of these posts, with such works as were necessary for their defense. Progress has also been made in opening communications between them and in raising supplies at each for the support of the troops by their own labor, particularly those most remote. With the Indians peace has been preserved and a progress made in carrying into effect the act of Congress making an appropriation for their civilization, with the prospect of favorable results. As connected equally with both these objects, our trade with those tribes is thought to merit the attention of Congress. In their original state game is their sustenance and war their occupation, and if they find no employment from civilized powers they destroy each other. Left to themselves their extirpation is inevitable. By a judicious regulation of our trade with them we supply their wants, administer to their comforts, and gradually, as the game retires, draw them to us. By maintaining posts far in the interior we acquire a more thorough and direct control over them, without which it is confidently believed that a complete change in their manners can never be accomplished. By such posts, aided by a proper regulation of our trade with them and a judicious civil administration over them, to be provided for by law, we shall, it is presumed, be enabled not only to protect our own settlements from their savage incursions and preserve peace among the several tribes, but accomplish also the great purpose of their civilization. Considerable progress has also been made in the construction of ships of war, some of which have been launched in the course of the present year.
