_Ordnance Sergeants._ Both are alike charged with the care and preservation of the artillery property and stores at the several garrisons, arsenals, and magazines.
In our army we have fifty-eight of these guards, viz: fifteen commissioned military store-keepers, and forty-three ordnance sergeants.
We seldom have more than this number of permanent posts; each one can therefore be supplied with an artillery guard for the care of the artillery stores.

In the French service there are three hundred and fifteen of these artillery guards; they are divided into three classes.

_Artificers._--This class of men are employed in the construction and repairs of military materials.

In most of our arsenals and armories it is thought to be best to employ unenlisted workmen, by the piece or contract.

Nevertheless a limited number of enlisted men of this description are found to be both useful and necessary.
