“How soon before we can start?” asked Bob.

“Not for a couple of weeks,” replied Jerry. “School closes a week from to-day, and then it will take us a week to get ready after that. We haven’t much time now, on account of examinations. I’ve got to do some hard studying to pass.”

“So have I,” admitted Bob. “Well, then, we’ll say in a couple of weeks. Maybe Noddy won’t be around by then, and we’ll be all right. Did you hear from Mr. Glassford, Jerry?”

“Yes, and he says he’ll have the Comet all ready for us. He won’t be there himself, as he has to come east, but he’s paid a man to take charge of the motorship for us. The auto will be ready in two weeks, also, for I had a letter from the factory where they’re repairing it. I wrote to ’em to make a few changes in it, to bring it up to date. Our motor boat, the Dartaway, needs a little overhauling, and then that will be in shape.”

Following the smashing of the original Dartaway in the freight wreck, the boys had bought a much larger and finer craft, with a cabin, and had named it after their first boat.

Their auto I have described in previous books. It was a large touring car, with plenty of room for the passengers and also compartments where food and supplies could be carried, and also a small tent with folding cots, so that in case they desired they could camp out wherever night overtook them. Recently a closed body had been put on the car, so that it was very comfortable to travel in, even during a storm.

The motorship Comet I have also described in other books, so I will only mention it briefly here. It was a combination of an aeroplane and dirigible balloon, and could be used as either or both.

The gas used in the bag was manufactured on board, as needed, and there was a comfortable cabin, sleeping berths and an engine room, fairly filled with motors, dynamos, air pumps, a gas generator and many other mechanical contrivances. The motorship could be kept aloft a number of days, and plenty of food and supplies could be carried, in addition to several passengers. It was an ideal craft of the air.

In the days that followed the motor boys were kept busy. When they were not “boning” away over their lessons they were getting the Dartaway in readiness for the trip. Professor Snodgrass remained as the guest of Mr. Slade, and the scientist spent most of his time wandering about the woods and fields looking for rare bugs.
