They had been up in the air several hours now, and the thrill of skimming along almost on a level with the clouds was wonderful. They did not want to descend. Professor Snodgrass was not enjoying himself, however, as he saw many curious insects, and as he had no other net with him he could not catch any of the winged creatures.

“Can’t you drop down, get my net, and come back again?” he asked.

“I think we’ll go down, but I don’t want to make another ascension until I have repaired the propeller,” said Mr. Glassford. “Though I’m afraid we’d have quite a task to locate your net.”

“Never mind, I have several more. I’ll bring two along next time.”

“But please don’t get them twisted up in the propeller,” begged Jerry.

“I’ll not.”

Mr. Glassford, who had resumed charge of the ship, now sent it down to the earth in a long slant. They had returned to a position over their tent, around which quite a crowd was now collected.

“It certainly is a great ship,” commented Ned. “I wish there was another aero carnival. We could enter it, and I’ll bet we could beat anything they had.”

“There’s going to be a big airship carnival next month, boys,” said Andy Rush, who seemed to keep abreast of aeronautic matters. “I was reading about it last night.”

“There is? Where?” asked Jerry.
