The Motor Boys in Strange Waters

"Shut your eyes," called Bob Baker to his friend Jerry Hopkins, as the two boys sat in the library of Bob's home.
"What for?"
"Never mind. Just shut 'em; that's all."
"No tricks now. I don't want a mouthful of salt, or find that I'm all tangled up in a folding chair."
"No, this is something on my own account. Shut your eyes."
"All right. Here goes."
Jerry accommodatingly closed his eyelids. He opened them almost immediately as he heard a loud thump in the room.
"What was that?" he asked.
"That was yours truly," explained Bob.
"What doing?"

"I threw my Latin grammar and my algebra over there behind the bookcase."
"What in the world did you do that for?"
"Because I don't want to see 'em again until after vacation, and I didn't want to see where they fell for fear I'd be tempted to do some studying to work off my conditions. And I didn't want you to see where they went to for fear you'd tell me. So I just shut my eyes and let 'em go. They're safe, and when they clean house in the fall they'll find 'em. It'll be time enough then to begin studying. Vacation's here! Hurrah for a good time with nothing to do but have fun!"
"That's so; to-day is the last one for school for more than two months," remarked Jerry.
"As if you'd forgotten it!"
"Well, I wasn't thinking of it, though I'm glad we don't have to do any more studying for a while. There'll only be the closing exercises this afternoon and then—"
"Yes, then what?" asked Bob. "What are we going to do with ourselves this vacation?"
"Go somewhere in our motor boat I guess," replied Jerry. "But isn't that a Latin grammar I see sticking out under the edge of the bookcase?" and he pretended to start to pull forth the volume.

"Don't you dare touch it!" cried Bob. "Shut your eyes so you can't see it!"
Jerry, however, dodging Bob's outstretched arms, reached for the book.
