PREPARING FOR A VOYAGE

"This note."
"Oh, yes. But what made you think the writing looked like that of the crazy machinist who tried to wreck the projectile?"
"Because I once saw some of the crazy letters he sent us, and he wrote just like the man who gave Dick this note. But come on, let's hustle, and see what's up."
In a few minutes they came in sight of the white bridge, which was about a quarter of a mile down the road from the professor's house. The two boys kept well together, and they were watching for a first sight of the man in waiting.
"See anything?" asked Jack.
"No; do you?"
"Not a thing. Wait until we get closer. He may be in the shadow. It's dark now."
