Under the late organization of the artillery arm, with the exception of the colonel of the regiment of light artillery, there were no grades higher than lieutenant-colonel recognized. Three of the four colonels of artillery provided for by the act of Congress of the 2d of March, 1821, were considered, therefore, as original vacancies, to be filled, as the good of the service might dictate, from the Army corps. The Pay Department being considered as a part of the military establishment, and, within the meaning of the above-recited act, constituting one of the corps of the Army, the then Pay master-General was appointed colonel of one of the regiments. A contrary construction, which would have limited the corps specified in the twelfth section of the act to the line of the Army, would equally have excluded all the other branches of the staff, as well that of the Pay Department, which was expressly comprehended among those to be reduced. Such a construction did not seem to be authorized by the act, since by its general terms it was inferred to have been intended to give a power of sufficient extent to make the reduction by which so many were to be disbanded operate with as little inconvenience as possible to the parties. Acting on these views and on the recommendation of the board of general officers, who were called in on account of their knowledge and experience to aid the Executive in so delicate a service, I thought it proper to appoint Colonel Towson to one of the new regiments of artillery, it being a corps in which he had eminently distinguished himself and acquired great knowledge and experience in the late war. In reconciling conflicting claims provision for four officers of distinction could only be made in grades inferior to those which they formerly held. Their names are submitted, with the nomination for the brevet rank of the grades from which they were severally reduced.
