The “piece of her mind,” however, went undelivered when once the boys did arise, for in the absorbing story which they had to tell of the night’s occurrences, her sense of injury evaporated speedily. The recital occupied considerable time. At its conclusion, Bob, who had been looking so frequently at Della’s guest, Marjorie Faulkner, as to cause Frank to chuckle to himself, suggested they play tennis. But Della protested.

“That’s all we’ve had to do to-day while you boys slept,” she said. “We’re tired of tennis. Propose something else.”

“The airplane’s out of commission, or I’d take you up for a flight,” said Bob. “Wouldn’t you like that, Miss Faulkner?”

“Oh, wouldn’t I, just,” she exclaimed. “I’ve never been up in an airplane, and I’m dying to try it. What is it like? Does it make you sick?”

Bob grinned. Before he could reply, Frank interrupted.

“Say, Bob,” he exclaimed, “we ought to telephone the factory over in Long Island City right away, 175 and tell them to send a couple of mechanics over here with new wings and whatever else is needed. First, though, we ought to make a thorough inventory to see what we need.”

Bob agreed, and, accompanied by the girls, they repaired to the hangar. After returning to the house, Frank rang up the airplane factory, and gave the necessary orders. He was told the mechanics would arrive the next day with all that was required, but that putting the plane into condition would take three or four days at the least.

“Just when I had it all in good shape for flying,” mourned Bob, on his chum’s return. “Oh, what I’d do to that little monkey, Higginbotham, if I had the chance.”

He grinned as he uttered the threat, yet it could be seen that he was badly cut up by the damaging of the plane. Frank said nothing, but threw an arm over his shoulder as they walked back to the house, and for the remainder of the journey neither had much to say, leaving it to the girls to carry the burden of conversation.

Arrived at the house, they found Jack with Captain Folsom. The latter was introduced to the girls, whom he had not met on his arrival the night previous.
