"There's a dozen rats hanging to my boots!" cried Dick.

"And mine, too!" declared Jimmie.

The three boys on the outside continued to hurl refuse from the top of the wall into the chamber. This in a measure kept the rats back, and before many minutes Jimmie and Dick were drawn to the top of the barrier.

Their rubber boots were cut in scores of places by the sharp teeth of the rats, and even their clothing as high up as their shoulders showed ragged tears. A dozen or more rats hung to the boys' boots until the top was reached, then they dropped back screaming with baffled rage.

"Talk about your wild Indians!" exclaimed Tommy. "I never saw anything as vicious as that was! I told you boys not to open up an argument with those fellows! Mine rats are noted for their courage when attacked."

"How many bites did you get?" asked Elmer anxiously.

"I got half a dozen nips!" answered Jimmie.

"And so did I," Dick cut in.

"Well, you boys ought to get back to the room right away," Tommy suggested, "and have peroxide applied to the wounds. I've known of people dying of blood poison occasioned by rat bites."

"Have you got it in camp with you?" asked Elmer.
