"Fall in, men," said Lieut. Bowersox, bustling out from a good meal in the officers' room. "Fall in promptly. We must hurry up to catch the Looeyville train." The car for Louisville was filled with characters as to whom there was entirely too much ground for fear--gamblers, "skin-game" men, thieves, and all the human vermin that hang around the rear of a great army. Neither of the boys allowed themselves a wink of sleep, but sat bolt upright the entire night, watching everyone with steady, stern eyes. They recognized all the rascals they had seen "running games" around the camps at Murfreesboro, and who had been time and again chased out of camp even the whisky seller with whom Si's father had the adventure. The Provost-Guard had been making one of its periodical cleaning-ups of Nashville, and driving out the obnoxious characters. Several of these had tried to renew their acquaintance by offering drinks from well-filled bottles, but they were sternly repulsed, and Shorty quietly knocked one persistent fellow down with a quick whirl of his gun-barrel. When Shorty was hungry it was dangerous to trifle with him. They arrived at Louisville late in the morning, and were hurried across the river to Jeffersonville. Fortunately they were able to find there an eating-room where guns were not barred, and Shorty made amends for the past by ravaging as far as his arms could reach, holding his precious gun firmly between his knees. "Say, pardner," said the man who ran the establishment, "I'd much rather board you for a day than a week. Rebels must've cut off the supply-trains where you've bin. You're not comin' this way agin soon, air you? I'm afraid I won't make 'nough this month to pay my rent." Lieut. Bowersox came in with a telegram in his hand. "We won't go on to Indianapolis," he said. "I'm ordered to wait here for our squad, which will probably get here by to-morrow evening." A wild hope flashed up in Si's mind. "Lieutenant," he said, "we live right over there in Posey County. Can't you let us go home? We can make it, and be back here before to-morrow night." "I don't know," said the Lieutenant doubtfully, as he mentally calculated the distance to Posey County. "I hadn't ought to let you go. Then, you can't have more than an hour or two at home." "O,' goodness; just think o' havin' one hour at home," ejaculated Si. "It seems too bad," continued the Lieutenant, moved by Si's earnestness, "to bring you this near, and not let you have a chance to see your folks. "It'll be a risk for me, and there are not many men in the regiment I'd take it for, but I'll let you go. "Remember, it'll make a whole lot of trouble for me if you're not here by to-morrow evening." "We'll be here by to-morrow evening, if alive," he pledged himself. "Well, then, go," said the Lieutenant.
