"Well, dad!" he exclaimed. "Here we are again, safe and sound. Made a record, too. Touched ninety miles an hour at times—didn't we, Mr. Sharp?"

"That's what," agreed a tall, thin, dark-complexioned man, who followed Tom Swift more leisurely in his exit from the cabin. Mr. Sharp, a veteran aeronaut, stopped to fasten guy ropes from the airship to strong stakes driven into the ground.

"And we'd have done better, only we struck a hard wind against us about two miles up in the air, which delayed us," went on Tom. "Did you hear us coming, dad?"

"Yes, and it startled him," put in Mrs. Baggert. "I guess he wasn't expecting you."

"Oh, well, I shouldn't have been so alarmed, only I was thinking deeply about a certain change I am going to make in the submarine, Tom. I was day-dreaming, I think, when your ship whizzed through the air. But tell me, did you find everything all right at Shopton? No signs of any of those scoundrels of the Happy Harry gang having been around?" and Mr. Swift looked anxiously at his son.

"Not a sign, dad," replied Tom quickly. "Everything was all right. We brought the things you wanted. They're in the airship. Oh, but it was a fine trip. I'd like to take another right out to sea."

"Not now, Tom," said his father. "I want you to help me. And I need Mr. Sharp's help, too. Get the things out of the car, and we'll go to the shop."

"First I think we'd better put the airship away," advised Mr. Sharp. "I don't just like the looks of the weather, and, besides, if we leave the ship exposed we'll be sure to have a crowd around sooner or later, and we don't want that."

"No, indeed," remarked the aged inventor hastily. "I don't want people prying around the submarine shed. By all means put the airship away, and then come into the shop."

In spite of its great size the aeroplane was easily wheeled along by Tom and Mr. Sharp, for the gas in the container made it so buoyant that it barely touched the earth. A little more of the powerful vapor and the Red Cloud would have risen by itself. In a few minutes the wonderful craft, of which my readers have been told in detail in a previous volume, was safely housed in a large tent, which was securely fastened.
