10th.—We have commenced moving our camp equipage from Camp Vanderwerken to this place, to be named Camp Griffin—I suppose for Capt. Griffin, of one of the batteries of the regular army. Capt. G., with his battery, has been one of us and with us since we crossed the Potomac. We have had much trouble and vexation to-day in establishing medical headquarters for the regiments of our brigade, but after much ordering of us and changing of orders, we are at last to take charge of the stone house of Mr. Jno. N. Johnson, in which, and in the tents we are able to pitch, we hope to make comfortable all the sick of our brigade.
