"I guess you had better give Mr. Swift a hand, Captain Mentor," spoke the millionaire yacht owner. "I don't know what good the wreck can be, but we owe considerable to Mr. Swift and his friends, and the least we can do is to aid them in anything they ask. So, Captain, if you don't mind, you and the mate bear a hand. In fact, we'll all help, and move the wreck so far up that there will be no danger, even from tidal waves."

Tom looked pleased at this order, and soon he and all the men in the little party were busy taking out the electrical apparatus, and moving it farther inland.

"What are you going to do with it, Tom?" asked Mr. Damon, in a low voice, as he assisted the young inventor to carry a small dynamo, that was used for operating the incandescent lights.

"I hardly know myself. I have a half-formed plan in my mind. I may be able to carry it out, and I may not. I don't want to say anything until I look over the machinery, and see if all the parts which I need are here. Please say nothing about it."

"Bless my toothpick! Of course, I'll not," promised Mr. Damon.

When the removal of most of the machinery of the wrecked airship had been completed, Mrs. Nestor exclaimed:

"Well, since you are moving that out of harm's way, don't you think it would be a good idea to change our camp, also? I'm sure I'll never sleep a wink, thinking that part of the island may fall into the ocean at any moment in the night, and create a wave that may wash us all out to sea. Can't we move the camp, Mr. Swift?"

"No reason why we can't," answered the lad, smiling. "I think it would be a good plan to take it farther back. We are likely to be here some time, and, while we are about it, we might build more complete shelters, and have a few more comforts."

The others agreed with this idea, so the little shacks that had been erected were taken down, and moved to higher ground, where a better outlook could be had of the surrounding ocean. At the same time as safe a place as possible, considering the frequent earthquakes, was picked out--a place where there were no overhanging rocks or cliffs.

Three huts were built, one for the two ladies, one for the men, and third where the cooking could be done. This last also held the food supplies and stores, and Tom noted, with satisfaction, that there was still sufficient to eat to last over a week. Mr. Fenwick had not stinted his kitchen stores.
