Going over to the tree, they saw the ghastly truth. A man wearing a garment something like a Russian blouse, but of the field-gray military shade of the Germans (as well as the boys could make out by the aid of a lighted match) was hanging by his garment which had caught in a low spreading branch of the tree. His feet were just clear of the ground and as the breeze blew he swayed this way and that, the gathering strain upon his garment behind the neck throwing his limp head forward and giving his shoulders a hunched appearance, quite in the manner of the clog dancer. The German emblem was blazoned upon his blouse and superimposed in shining metal upon the front of his fatigue cap. Even as they paused before him he seemed to bow perfunctorily as if bidding them a ghastly welcome. Tom's scout instinct impelled him instantly to fall upon the ground in search of enlightening footprints, but there were none and this puzzled him greatly. He felt sure that the man had not been strangled, but had been killed by impact with some heavier branch higher up in the tree; but he must have made footprints before he climbed the tree, and---- Suddenly he jumped to his feet, remembering what he had thought to be a guardhouse. It lay a hundred or more feet beyond the dangling body and as they neared it it lost its sentinel-station aspect altogether. "Well--what--do you--know about that?" said Archer. "It's an observation balloon, I'll bet," said Tom. "A Boche sausage! Look for another man before you do anything else--there's always two. If he's around anywhere we might get into trouble yet." It was a wise thought and characteristic of Tom, but the other man was quite beyond human aid. He lay, mangled out of all semblance to a human being, amid the tangled wreckage of the car. The fat cigar-shaped envelope of the balloon stood almost upright, and though it looked not the least like a police telephone station now, it was easy to see how, from a distance in the dim light, it might have suggested a little round domed building. "How do you s'pose it happened?" Archer asked. "I don't know," said Tom. "It's an observation balloon, that's sure. Maybe it was on its way back from the lines to somewhere or other. Hurry up, let's see what there is; it'll be daylight in two or three hours and we don't want to be hanging around here. They might send a rescue party or something like that, if they know about it." "Morre likely they don't," said Archer. "I guess it only happened tonight," said Tom, "or more gas would have leaked out. Let's hunt for the eats and things."
