His chum made the necessary adjustments to the mechanism and then, there being nothing more to slide down the mountainside the avalanche was ended.  But what a mass of wreck and ruin there was!  It was as if a mighty earthquake had torn the mountain asunder.

“It’s a good thing it wasn’t on a side of the mountain where people lived,” commented Ned, as the airship rose high toward the clouds.  “If it had been, there’d be nothing left of ’em.  What hair-raising stunt are you going to try next, Tom?”

“I don’t know.  I expect to hear from Mr. Period soon.

“Hear from Mr. Period?” exclaimed Mr. Nestor.  “How are you going to do that, Tom?”

“He said he would telegraph me at Berne, Switzerland, at a certain date, as he knew I was coming to the Alps to try for some avalanche pictures.  It’s two or three days yet, before I can expect the telegram, which of course will have to come part way by cable.  In the meanwhile, I think we’ll take a little rest, and a vacation.  I want to give the airship an overhauling, and look to my camera.  There’s no telling what Mr. Period may want next.”

“Then he didn’t make out your programme completely before you started?” asked Mr. Nestor.

“No, he said he’d communicate with me from time to time.  He is in touch with what is going on in the world, you know, and if he hears of anything exciting at any place, I’m to go there at once.  You see he wants the most sensational films he can get.”

“Yes, our company is out to give the best pictures we can secure,” spoke Mary’s father, “and I think we are lucky to have Tom Swift working for us.  We already have films that no other concern can get.  And we need them.”

“I wonder what became of those men who started to make so much trouble for you, Tom?” asked Mr. Damon.

“Well, they seem to have disappeared,” replied our hero.  “Of course they may be after me any day now, but for the time being, I’ve thrown them off my track.”

“So then you don’t know where you’re going next?” asked Ned.

“No, it may be to Japan, or to the North Pole.  Well, I’m ready for anything.  We’ve got plenty of gasolene, and the Flyer can certainly go,” said Tom.

They went down to earth in a quiet spot, just outside of a little village, and there they remained three days, to the no small wonder of the inhabitants.  Tom wanted to see if his camera was working properly.  So he developed some of the avalanche pictures, and found them excellent.  The rest of the time was spent in making some needed repairs to the airship, while the young inventor overhauled his Wizard machine, that he found needed a few adjustments.

Their arrival in Berne created quite a sensation, but they were used to that.  Tom anchored his airship just outside the city, and, accompanied by Ned, made his way to the telegraph office.  Some of the officials there could speak English, though not very well.
