“You did! And did he speak to you?” asked Bob.

“Just sort of nodded and thanked me for the way we fellows pulled him out of the water. He wasn’t very enthusiastic over it, though, and he looked rather thin and pale, I thought.”

“Maybe he was hurt worse than we imagined,” suggested Bob. “Well, if he doesn’t make any trouble for us, I’ll be satisfied. But I guess it’s time I went home. I want to get plenty of sleep, for I’m going to get up early.”

“Same here,” said Jerry. “I guess everything is in shape. We’ll meet at my house, as that’s nearest the river, and then we’ll get started as early as we can.”

“It’s all settled then; is it?” asked Professor Snodgrass.

“Everything,” replied Ned. “We’ll go by motor boat to Pittsburg, get our auto there, and ride across to Denver, and from there make the rest of the trip by airship. I guess that’s the best way to get down into the Grand Canyon.”

“It’s really the only way,” said Mr. Snodgrass. “Boats are almost out of the question, and to follow the trails down the sides of the big chasm wouldn’t help us much, for Snake Island is far off from any of the places by which you can get down to the river’s edge. But with an airship we can descend as well as if we were in an elevator. Yes, I think you boys have made the best possible plan.”

Bob and Jerry left Ned’s house soon after this, and, on the way to their homes they went past the Nixon residence. Bob, looking up, exclaimed:

“Noddy’s sitting up late to-night. There’s a light in his room.”
