_Thursday, Jan. 21._--Devoted the main part of the day to Armory-square hospital; went pretty thoroughly through wards F, G, H, and I; some fifty cases in each ward. In ward F supplied the men throughout with writing paper and stamp'd envelope each; distributed in small portions, to proper subjects, a large jar of first-rate preserv'd berries, which had been donated to me by a lady--her own cooking. Found several cases I thought good subjects for small sums of money, which I furnish'd. (The wounded men often come up broke, and it helps their spirits to have even the small sum I give them.) My paper and envelopes all gone, but distributed a good lot of amusing reading matter; also, as I thought judicious, tobacco, oranges, apples, &c. Interesting cases in ward I; Charles Miller, bed 19, company D, 53d Pennsylvania, is only 16 years of age, very bright, courageous boy, left leg amputated below the knee; next bed to him, another young lad very sick; gave each appropriate gifts. In the bed above, also, amputation of the left leg; gave him a little jar of raspberries; bed J, this ward, gave a small sum; also to a soldier on crutches, sitting on his bed near.... (I am more and more surprised at the very great proportion of youngsters from fifteen to twenty-one in the army. I afterwards found a still greater proportion among the southerners.) Evening, same day, went to see D. F. R., before alluded to; found him remarkably changed for the better; up and dress'd--quite a triumph; he afterwards got well, and went back to his regiment. Distributed in the wards a quantity of note-paper, and forty or fifty stamp'd envelopes, of which I had recruited my stock, and the men were much in need. FIFTY HOURS LEFT WOUNDED ON THE FIELD
