"Well—er—not exactly, but you know what I mean, Dave."
"So I do, and I agree with you."
The start of the trip was made in fine shape, and for a little while they sailed along in company with two other ice-boats belonging to other students. But then the others turned back, and the Snowbird continued on the course alone.
"This is certainly grand!" cried Dave, enthusiastically. He was sitting at the bow, holding fast with one hand and holding on his cap with the other. "My! but we are rushing along."
"It's just the right kind of a breeze," said Henshaw.
"Beats skating, doesn't it?" came from Roger. "We must be making about a mile a minute!"
"We won't dare to go too far," said Messmer. "Remember, we've got to get back, and that will take longer."
"Maybe the wind will change."
"No such luck, I am afraid."
