"Now, great Scott, what's up?" said Si angrily, as he quickly surveyed the surrounding country. He saw that they were not attacked, and then clambered to the top of the car, where he noticed little wreaths of powder-smoke lingering around the squad in which were Jim Humphreys, little Pete Skidmore and Wes. Brown. "What're you young whelps shootin' for?" demanded Si. They were all so abashed at his sternness that they could not find their tongues for reply, until little Pete piped up: "Why we've bin talkin' to the train men, and they said they wuz shot at wunst, about a year ago, from that swamp back there, and we got some catridges from them, and we thought we saw something moving in there, though Jim Humphreys said it wuz only burned stumps that we took for men, and them other boys back there had bin shootin' off their gunn and tryin' 'em, and we thought we could too--" "You little brats," said Si; "didn't you hear my orders about firin' before we started? If another boy shoots without my orders I'll tie him up by the thumbs! Got any more catridges? Give me every one of 'em." The boys all protested that every cartridge was gone. Si assured himself of this by examination, savagely scored the train men for giving them ammunition and threatened trouble if any more was, and having relieved his mind returned to his paper in the caboose-car. The train ran on to a switch where there was another carrying a regiment going home on veteran furlough. Si and Shorty knew some of the men, and in the pleasure of meeting them and in hearing all the news from the front forgot that their boys were mingling with the others and being filled full of the preposterous stories with which veterans delight to stuff new recruits. Finally the whistles gave notice that the trains would move. Si got his boys back on the cars, and renewing his caution about taking care of themselves, holding on tightly and looking out for overhanging branches, returned with Shorty to their car and their occupations. "We're comin' to Stewart's Crick, Shorty," said Si, looking up from his paper. "Recollect that hill ovyr there? That's where they had that battery that the Colonel thought we wuz goin' to git. Great Scott, the mud and briars in that old field!" "Yes," said Shorty, negligently, with his eyes fixed on the backs of the cards. "But that's ancient history. Say, I've got these marks down fine at last. They're just as plain as A, B, C. You see, when that corner o' the square comes out clear to the edge it's clubs, every time, and there's just as many spots as there is of lines--"
