Neither of them had been even scratched, but a certain amount of damage had befallen one of the planes, which might have been remedied on the spot in time to allow them to get back home easily, only for the unfortunate fact that just when they needed a monkey wrench the worst kind, it was discovered to be missing; perhaps the only occasion when such a thing had happened with the boys.

"I just saw somebody go into the barn there," remarked Frank, as they approached the large outbuildings connected with the successful farm of Josiah Quackenboss.

"Yes, and it was the farmer himself," added Andy. "I know him pretty well; and I guess you do too, because your father brought his little boy around when everybody thought he didn't have a single chance to get well. I don't believe we'll have any trouble getting Felix Boggs to look after our machine tonight, Frank."

They quickly reached the door of the barn and could hear the steady fall of the streams of milk passing into the buckets as the farmer and his hired hand pursued the regular business of the evening.

As the two boys entered, the half grown boy started up with an exclamation of alarm, for of course both Andy and Frank looked rather queer. Each of them had on a white woolen hood that fitted close to head and shoulders, for the air in the upper currents was very cold these days, and secured to this were goggles to protect the eyes, so that they would not water and dim the vision of the aviator at just a critical instant when they needed clear sight. Then they also wore warm colored mackinaw jackets, so that altogether Felix had reason to be startled when two such "sights" suddenly entered the barn. Why, even the gentle cows showed evidence of nervousness, and came near upsetting the milk buckets.

"Hello, Mr. Quackenboss!" called out Andy, cheerfully; "we're the Bird boys, and we've dropped in on you without an invitation. The fact is, we had a little trouble with our aeroplane, and landed in your field. How much rent will you charge us, Mr. Quackenboss; to let our machine lie there over night? It needs a little fixing which we can't do until morning."

Of course Andy was joking when he said this, and the farmer knew it as well as anything. He laughed as he came around out of the stall and offered his rough hand to each of the boys.

"How are you, Andy and Frank Bird?" he said, hearty. "Say, you did give us a little start when we first saw you. D'ye know what I thought boys? Why, I was just reading in the county paper about how the bank up at Jasper was robbed by two men last week. It told how they had their faces hid back of red handkerchiefs, just like they always do out West, you know. And first thing I sighted you two, my heart nigh about jumped up in my mought, because I thought them yeggs had dropped around to see if I'd collected my monthly milk accounts in town. And about leavin' your aeroplane in my field, why, there's little that I wouldn't do for the son of the man who saved my Billie, when everybody said he'd never get well again."

"We thought you might let us show Felix here where the aeroplane lies, and that we could arrange with him to kind of keep an eye on it tonight. Of course, there isn't one chance in a thousand that anything'd happen to injure it; but then that machine represents a heap of hard work, and considerable money besides, so we don't care to take chances with it.

"Sure he can, just as well as not, eh, Felix? Suppose you go out right now, and I'll finish the milking. In the morning I want to take a look at that contraption myself. I've seen you boys sailing around more'n a little, but never got close up to examine the aeroplane. Well, I guess all the money going couldn't tempt me to go with one of you. Skip along, Felix, now."
