This was a field where possibly he excelled Jack in proficiency, for he had had more practical experience with motors than the Western lad. If it had been anything connected with horses now, Amos would have known that he must take a back seat, for the ranch boy was quite at home along those lines. For once, Jack was ready and willing to allow his chum to work while he looked on. He had seen the nurse staring hard at that small emblem of the country across the sea which Amos so proudly carried on his coat lapel. “You are really and truly Americans?” she remarked, turning to Jack. “Oh! yes, we belong over there, and have come across because we had a very important errand,” he told her. “We were in England only recently, and met your Lord Kitchener, to whom we had a letter of introduction from the father of my cousin, who used to be great friends with him long ago out in Egypt or somewhere. He gave us a paper that is turning out to be a great help in our search.” Amos was working busily at the tire, with the Belgian youth to assist him; but he evidently heard every word they said, for he turned to nod his head at this juncture and remark: “Your K. of K. is the finest gentleman ever, for he fixed us out, and right now we’re hoping to be able to find my brother before a great while. Jack, you explain about it, won’t you, please, while I knuckle down to this job.” “Then you are looking for some one who has been caught over here by the war breaking out?” suggested the nurse. “There are thousands in that same trouble. I myself have met many, and we try to assist them as far as our limited means will allow. Oh! if there ever was a time when I wished for a thousand arms it is in these terrible days and nights. For many weeks each day has brought new hosts of poor wounded fellows. I sometimes think the better part of our young manhood will be cut off if this thing continues much longer. But you did not answer my question.” “Well, we are looking for some one,” Jack admitted, “though he was not caught in Belgium by the breaking out of the war. On the contrary, this brother of my chum, who is about ten years his senior, must have offered his services to your Government as an experienced aviator, and was accepted because the supply of air pilots just then was not equal to the demand. We have reason to believe he has been serving in that capacity, and done a few pretty daring things along his line of scouting and the like.” “I have met with dozens of aviators,” she told him. “In fact, for a time it happened that I was attached to a corps particularly assigned to cases of necessity among the pilots of aeroplanes; for you must know they frequently meet with serious accidents aside from the dangers they run while over the enemy’s lines.” Again did Amos’ head bob up. “Well, I declare, that’s queer,” he was saying. “I wonder now if you ever did happen to meet my brother.”
