THE strangest feeling possessed Si and Shorty when once in the camp of their old regiment, and after the first hearty welcome of their comrades was over. There was a strangeness about everything that they could not comprehend. It was their regiment--the 200th Ind.; it was made up of the same companies, with the great majority of the men the same, but it was very far from being the 200th Ind. which crossed the Ohio River in September, 1862. Marvelous changes had been wrought by 18 months' tuition in the iron school of war, in the 10 separate herds of undisciplined farmer boys which originally constituted the regiment. Yellow, downy beards appeared on faces which had been of boyish smoothness when the river was crossed, but this was only one of the minor changes. There was an alertness, a sureness, a self-confidence shining from eyes which was even more marked. Every one carried himself as if he knew precisely what he was there for, and intended doing it. There was enough merriment around camp, but it was very different from the noisy rollicking of the earlier days. The men who had something to do were doing it with systematic earnestness; the men who had nothing to do were getting as much solid comfort and fun as the situation afforded. The frothy element among officers and men had been rigorously weeded out or repressed. All that remained were soldiers in the truest sense of the word. The change had been very great even since the regiment had lined up for the fearful ordeal of Chickamauga. "Did you ever see a gang o' half-baked kids get to be men as quick as these boys?" Si asked Shorty. "Think o' the awkward squads that used to be continually fallin' over their own feet, and stabbing theirselves with their own bayonets." "Seems so," answered Shorty, "but I don't know that they've growed any faster'n we have. Walt Slusser, who's bin Orderly at Headquarters, says that he heard Capt. McGillicuddy tell Col. McBiddle that he'd never seen men come out as me and you had, and he thought we'd make very effective noncommish." "Probably we've all growed," Si assented thoughtfully. "Just think o' McBiddle as Lieutenant-Colonel, in place o' old Billings. Remember the first time we saw McBiddle to know him? That time he was Sergeant o' the Guard before Perryville, and was so gentle and soft-spoken that lots o' the boys fooled themselves with the idee that he lacked sand. Same fellers thought that old bellerin' bull Billings was a great fightin' man. What chumps we all wuz that we stood Billings a week." "Wonder if I'm ever goin' to have a chanst for a little private sociable with Billings? Just as I think I'm goin' to have it, something interferes. That feller's bin so long ripe for a lickin' that I'm afraid he'll be completely spiled before my chanst comes."
