But if they were surprised at seeing seated therein two men in the uniforms of the United States army, their feelings hardly compared with those of Lieutenant Mackinson, Joe, Slim and Frank Hoskins, as they recognized, stepping out of the Taube, Jerry and the observation officer with whom he had occupied the stationary balloon practically all of that day. "Who are you?" "What happened?" "Where have you been?" and a score of similar questions were fired at them by the other soldiers as Jerry shook hands with his friends, and the officer smilingly made away to file his report. "Well, to put it briefly," Jerry said, in answer to the general demands for information, "we were anchored off there most of the day in an observation balloon. Late in the afternoon a shell cut our cable, and almost before we knew it we had been carried behind the German lines. "The fight was still commanding the attention of almost everyone, and after descending a little by permitting some of the gas to escape, we jumped over the side of the basket and came down on our parachutes. I landed in a deserted barnyard, and the officer hit the earth only a short distance away. "While we were hiding there, debating just what we should do, along comes a Taube, and its pilot decides to make a landing almost at that same place. Well, the officer being a pretty good pilot, we decided to have that machine. We got it, and I guess that pilot's head aches yet where I plumped him with the butt of my gun when he wasn't expecting anything of the kind. "But some other German aviators saw the affair, apparently recognized our uniforms, and hardly gave us time to make a decent start. "Say," Jerry concluded, "they certainly did pebble us with machine-gun bullets! I saw two bounce off the propeller, and one broke a wire on the left wing, making us flap around rather uncertainly for a few minutes. It was a great race, though, and we considered our greatest danger lay in landing on this side. We knew it would be recognized for a German plane, and we were afraid we'd be fired on before we could make our identity known." Led by the lieutenant and Jerry, the party tramped back to where, shortly, mess was to be served. "That air certainly does give a fellow an appetite," said Jerry, as he splashed more of the clear cold water over his face. An orderly stepped up to Lieutenant Mackinson and handed him a large, officially stamped envelope. As he tore it open and read the brief note within, a pleased smile spread over his face. From the same envelope he extracted three smaller ones. He handed one to each of the lads who had accompanied him over on the _Everett_, according to the way they were addressed.
