Colonel H. L. ABBOT,

Commanding Siege Artillery, Broadway Landing, Va.:

SIR: I have to acknowledge the receipt of your letter of the 10th instant with regard to 13-inch mortar fuses. In reply I would state that the fuses referred to were recently received here from the North, and that those of the same lot which I have examined since the receipt of your letter appeared to be perfectly good. If you will return me some of those which were filled with sawdust or otherwise defective. I will have the matter fully investigated. In some cases I find the priming in the top of the fuse is separated from the case, and if this should happen to fall out the fuse would not be likely to ignite; but by leaving the paper can on the fuse and cutting a small hole in it the priming will be kept in its place and there should be no difficulty with the ignition of the fuse.

Respectfully, your obedient servant,

T. EDSON,

Captain of Ordnance, Commanding.
