My Dear Sir
I wrote you three days ago and sent by same mail a little book, which I think will be useful.
I have ordered and unless my arrangements fail shall have ready for shipment on the 10th the instruments I proposed to purchase for you and with it 25 shell and 25 canister cartridges & all necessa-
ries except powder which you had better order from St. Louis The necessary quantity for these cartridges will be of coarse powder, 12 lbs. and perhaps ¼ that of rifle powder for charging the shells. I shall send you by private conveyance if possible instructions for charging &c. so clear that I think you will have no difficulty to use the instrument with the best effect if
there should unfortunately be occasion.
One discharge of it at musket range is considered equally effective with a simultaneous fire of 100 muskets – while its moral effect in producing consternation & panic upon an enemy especially of undiscplined men is far greater.
If you can use it properly as I doubt not you will, it is worth a dozen field pieces.
It will come by the under ground, via Chicago & [Peneuch?], as agreed –
