The work of the military commission still continues, and new as the proceedings are of course secret, it is impossible now to state how many will be convicted. The camp would be in a starving state but for the potatoes found in the Indian fields; but I learn that a small provision train will reach me to-morrow, not sufficient, however, to justify a farther advance into the Indian country.

Unless a full supply of provisions and forage, with 500 mounted men at least, can be sent on at once, the campaign may be considered as closed for this autumn. The grass is already so dry as to afford insufficient nourishment to the horses and cattle, so that grain cannot be dispensed with, and there is none except unshelled corn on this side of Fort Ridgely.
