headquarters to go and give Macpherson a hand as helper.

The colonel smiled. He knew what was in the wind. The Scot knew well where he could obtain helpers in plenty if he needed them. But Colonel Marker was as ready to help the Brighton boys as was the sergeant-major, so he smilingly acquiesced, and the next morning Louis came to camp attired in a suit of blue dungarees over his khaki.

In ten days' time Macpherson had taken the French lad to his heart, and was never so happy as when working away with him over a refractory engine and chatting along in a seemingly never-ending stream of engine small-talk. All of which was meat and drink to Louis, and was rapidly acquainting him with much that it would otherwise have taken him years of experience to acquire.

Joe Little and Jimmy Hill had a council of war with Louis Deschamps one night. These three were fast growing to be closer than brothers. What one of them had he was anxious the other two should share at once.

"I think I can see my way to get you fellows working in the hangars,"
Louis said.

"Mac will help us. I never saw such a good friend. I told him you fellows were anxious to get closer to the planes and he is turning it over in his mind. He will have a scheme soon, and when he does, it will go through all right."

Macpherson had a scheme, but just how and when to try to put it into operation was the question. He had a talk with Parks, the head instructor, one afternoon, and told Parks about the Brighton boys and their keenness to learn more about flying.

"You could do with those kids," said Mac "They are really too big by now to be called kids, as a matter of fact. Why, they will be flying soon themselves. Why don't you ask the major if you can't have two of them down here to help clean and tune up the school machines? It is a bit irregular, but so is their being here at all. I don't see why, if the Old Man can use them around the offices, we can't have a couple of them here. I have had the young Frenchman here with me now for some time, and he is worth a lot to me. He says two others, one named Hill and the other Little, want to get down to the hangars. Be a good chap and ask the major about it."

Parks did. The major was very busy at the time, and said, "I guess so," and let the matter go at that. Parks passed that laconic permission on to the sergeant-major, and the two boys reported to Parks forthwith.

That left Bob Haines, Harry Corwin, Archie Fox and Dicky Mann at headquarters to be generally useful. They had come to be on the best of terms with the sergeant-major, and when they pointed out to him that the three boys in the hangars were "having all the fun," he suggested that he so assign them to duty that but two of them would be "on" at the same time. Thus when Bob and Dicky Mann were standing ready for whatever might be required of them, Harry and Archie were free to spend their time in the hangars, where the sergeant-major could lay his hand on them in case of sudden calls.

Thus the summer was not far advanced before the Brighton boys were in the very thick of the flying game, not as onlookers, but as parts of the machine into which the various component parts of the camp and its numerous units were rapidly becoming merged.

If they had not tried to learn, the Brighton boys must have picked up some general information about aeroplanes and flying. With their special eagerness they were rapidly becoming well acquainted with most details of the work of the airmen. No casual word in their hearing fell on barren ground. When one of them mastered a new idea, he passed it on to the others.

None of the boys studied the machines themselves more devotedly than did Harry Corwin. Close application to many a dry volume bore good fruit. He felt he could set up a Farman type biplane by himself.

One morning Harry was standing beside a monoplane of the Bleriot type, which had come from somewhere as an old school machine, and had not been much in demand owing to the fact that no other monoplanes were in evidence at the camp, when an army airman, an entire stranger to Harry, came out of the hangar and glanced at the engine in evident preparation for a flight.

The airman was about to start the engine when Harry noticed that the elevator control wires were crossed. Whoever had attached them had done so mistakenly. Harry could hardly believe the evidence of his eyes, yet there it was, undeniable. Stepping forward, he said to the airman: "Excuse me, but your control wires are not right."

The flying man was little more than a novice, and sufficiently young to resent interference on the part of one obviously younger than himself. Besides, he had connected up those control wires himself. He glanced hurriedly at the terminals, and seeing that they were apparently secure, thought the boy beside him must be mistaken. He missed the crossed wires. He said to Harry, with just a suspicion of superciliousness, "Oh, she is quite O.K., thanks," and started his engine and sprang into his seat as the plane moved off across the meadow.

Harry stood watching the receding plane with something akin to consternation in his heart. Naturally shy, he did not think of pressing his opinion, but he knew trouble was in store for the young airman, though in just what form it would come he could not figure out. The monoplane had not gone far along the grass before the flier tried to raise it. As the machine did not answer properly to the elevator, he thought something must have stuck, and jerked the lever as if to free it. Afterwards the airman was not clear as to just what happened.

Harry could see the airman was trying some maneuver, and as he looked, the plane rose nose first from the ground, almost perpendicularly and then took an odd nose-dive head into the ground. The plane was not many feet from the earth when it dived, but was far enough up to come to the ground with a bad crash. Harry could see a dash of white spray in the sunlight as the gasoline splashed upward at the moment of the smash. The monoplane heeled over and the pilot went out of sight behind the wreckage. The graceful white tail stood high in air.

Running as fast as he could, Harry got to the scene of the accident before the airman had risen from the ground. The strap which had held him into his seat had burst, and he had suffered a nasty spill. Investigation showed, however, that he was but little the worse, save for the shock and the fright. He was as pale as a sheet. Harry helped him to his feet and assisted him to take stock of his injuries. By the time they had discovered that no bones were broken and the bruises the young fellow had sustained were quite superficial, Parks, the head instructor, dashed up in a motor car. As he leaped out beside the wrecked plane, there was a frown on his face. "Another smash?" he queried.

Harry learned later that the young airman had already smashed up two machines that week before demolishing the old monoplane.

"What was wrong this time?" Parks spoke sharply.

Without hesitation the young pilot answered: "I must have hitched the old girl up wrong, some way. This friend here," nodding toward Harry, "was good enough to tell me before I started that I had mussed things up before I got into her. I was a fool not to have listened to him, but," and he paused, smiling, "but he looked pretty young to be giving advice. I wish now I had listened to him."

Parks turned to Harry. "You knew where the trouble was?"

"The control wires were crossed," Harry answered simply.

"You noticed that, did you?" continued Parks. "When have you seen this type of plane before?"
