"I forgot all about Dunton, the observer!" he exclaimed. "He may have landed in the river, too, or he may be injured and in need of help. Do you feel fit enough to help me look for him, Bart?"
"Oh, I'm as good as ever now," said Bart, with an attempt at a grin. "Guess I must have been born to be hung, because I don't seem to be able to get myself killed by any other method."
The boys set out on their quest, and were soon delighted to see the observer himself limping toward them. The latter caught sight of them at the same time, and waved his hand to them.
"Gosh, but I'm glad to see you!" he exclaimed, when they came within speaking distance. "I was afraid you'd both gone under, and if you had I'd never have forgiven myself for taking you up with me."
"We were just starting out to look for you," said Frank. "Where did you land?"
"In a good soft place," said the other. "The branches of a big tree. My ankle caught in a branch and got wrenched a little, but otherwise I'm O.K."
"I landed in the river, and Frank had to fish me out," said Bart. "But now that we're all safe, I'm beginning to wonder just where we are. The storm seems to be over, and I guess it's up to us to get back to camp as soon as possible, or they'll have us down as A.W.O.L."
"I'm not sure just where we are," responded Dunton, "but I hope we haven't landed among the Huns. They'd like nothing better than a chance to put us out of the way."
"Well, all we've got to do to get back is follow the river down," said Frank. "Let's go."
Following Frank's suggestion, they had not gone more than half a mile when, to their great satisfaction, they caught sight of an American sentry walking his post.
