I am aware it may be said, that this plan is defective; for there is no arrangement made, so as to remove one of the great objections to our present mode of promotion, with regard to officers of engineers, artillery, and marines; but I take a very simple view of this matter; for I would merely look to a list of officers of the regular army of all ranks, and to the dates of their commissions; and when a cornet or ensign of any regiment became by the regular routine of promotion a lieutenant, I would, as a matter of course, make any officer of engineers, artillery, or marines of the same standing, a lieutenant also, yet without giving him the additional pay till a vacancy occurred in his own corps; and I would do the same through the different gradations of ranks, until the officers of engineers or artillery had become lieut.-colonels. I would then style them, and cause them to act as chiefs of engineers or artillery, and which rank they should hold for the same number of years as lieut.-colonels commanding regiments, when, like them, they should become major-generals; and enabling them also to take advantage of the retirement from the country, and of the system to be proposed for the military fund, these accomplished officers, if they thought fit to remain upon the effective list, could become available for staff or any other appointments the same as other generals, and at the same period of life. Out of the effective list of major-generals, lieut.-generals, or generals, the Commander-in-chief, as at present, could select those whom it might be deemed advisable to employ upon the staff of the army, or for any particular object, and as it is to be presumed that their services might be constantly required, especially in our foreign possessions, few of them would be found an unnecessary burden upon the country.
