The Indian tribes within our limits appear also disposed to remain at peace. From several of them purchases of lands have been made particularly favorable to the wishes and security of our frontier settlements, as well as to the general interests of the nation. In some instances the titles, though not supported by due proof, and clashing those of one tribe with the claims of another, have been extinguished by double purchases, the benevolent policy of the United States preferring the augmented expense to the hazard of doing injustice or to the enforcement of justice against a feeble and untutored people by means involving or threatening an effusion of blood. I am happy to add that the tranquillity which has been restored among the tribes themselves, as well as between them and our own population, will favor the resumption of the work of civilization which had made an encouraging progress among some tribes, and that the facility is increasing for extending that divided and individual ownership, which exists now in movable property only, to the soil itself, and of thus establishing in the culture and improvement of it the true foundation for a transit from the habits of the savage to the arts and comforts of social life. As a subject of the highest importance to the national welfare, I must again earnestly recommend to the consideration of Congress a reorganization of the militia on a plan which will form it into classes according to the periods of life more or less adapted to military services. An efficient militia is authorized and contemplated by the Constitution and required by the spirit and safety of free government. The present organization of our militia is universally regarded as less efficient than it ought to be made, and no organization can be better calculated to give to it its due force than a classification which will assign the foremost place in the defense of the country to that portion of its citizens whose activity and animation best enable them to rally to its standard. Besides the consideration that a time of peace is the time when the change can be made with most convenience and equity, it will now be aided by the experience of a recent war in which the militia bore so interesting a part. Congress will call to mind that no adequate provision has yet been made for the uniformity of weights and measures also contemplated by the Constitution. The great utility of a standard fixed in its nature and founded on the easy rule of decimal proportions is sufficiently obvious. It led the Government at an early stage to preparatory steps for introducing it, and a completion of the work will be a just title to the public gratitude.
