The discretionary authority given to General Gaines to cross the Sabine and to occupy a position as far West as Nacogdoches, in case he should deem such a step necessary to the protection of the frontier and to the fulfillment of the stipulations contained in our treaty with Mexico, and the movement subsequently made by that officer have been alluded to in a former part of this message.  At the date of the latest intelligence from Nacogdoches our troops were yet at that station, but the officer who has succeeded General Gaines has recently been advised that from the facts known at the seat of Government there would seem to be no adequate cause for any longer maintaining that position, and he was accordingly instructed, in case the troops were not already withdrawn under the discretionary powers before possessed by him, to give the requisite orders for that purpose on the receipt of the instructions, unless he shall then have in his possession such information as shall satisfy him that the maintenance of the post is essential to the protection of our frontiers and to the due execution of our treaty stipulations, as previously explained to him.

Whilst the necessities existing during the present year for the service of militia and volunteers have furnished new proofs of the patriotism of our fellow citizens, they have also strongly illustrated the importance of an increase in the rank and file of the Regular Army.  The views of this subject submitted by the Secretary of War in his report meet my entire concurrence, and are earnestly commended to the deliberate attention of Congress.  In this connection it is also proper to remind you that the defects in our present militia system are every day rendered more apparent.  The duty of making further provision by law for organizing, arming, and disciplining this arm of defense has been so repeatedly presented to Congress by myself and my predecessors that I deem it sufficient on this occasion to refer to the last annual message and to former Executive communications in which the subject has been discussed.

It appears from the reports of the officers charged with mustering into service the volunteers called for under the act of Congress of the last session that more presented themselves at the place of rendezvous in Tennessee than were sufficient to meet the requisition which had been made by the Secretary of War upon the governor of that State.  This was occasioned by the omission of the governor to apportion the requisition to the different regiments of militia so as to obtain the proper number of troops and no more.  It seems but just to the patriotic citizens who repaired to the general rendezvous under circumstances authorizing them to believe that their services were needed and would be accepted that the expenses incurred by them while absent from their homes should be paid by the Government.  I accordingly recommend that a law to this effect be passed by Congress, giving them a compensation which will cover their expenses on the march to and from the place of rendezvous and while there; in connection with which it will also be proper to make provision for such other equitable claims growing out of the service of the militia as may not be embraced in the existing laws.
