"Great Scott!" exclaimed the lad, as he labored to close the shed door, "this is a blow all right, Tom! Do you think it's safe to go up?"

"I can't go up without a gale, Ned."

"Well, I'd think twice about it myself."

"Why, I counted on you going up with me."

"Burr-r-r-r!" and Ned pretended to shiver. "I haven't an accident insurance policy you know."

"You won't need it, Ned. If we get up at all we'll be all right. Catch hold there, and shift that rear weight a little forward on the rod. I expect Mr. Damon soon."

The eccentric man came in a little later, just as Tom and Ned had finished adjusting the mechanism.

"Bless my socks!" cried Mr. Damon. "Do you really mean to go up to-day, Tom?"

"I sure do! Why, aren't you going with me?" and Tom winked at Ned.

"Bless my—" began Mr. Damon, and then, evidently realizing that he was being tested he exclaimed: "Well, I will go, Tom! If the air glider is any good it ought to hold me. I will go up."
