"I like that old-time fight talk! But are you going to do anything to protect the wall to-night, Tom ?" "I am," announced the young chief engineer.
"What's the plan ?" "Let me think," urged Reade.

"Now, I believe, I have it.

We'll send one of the motor boats out here, with a foreman and four laborers.

They can arm themselves with clubs and patrol the water on both sides of the wall.
The 'Thomas Morton' has a small search-light on her that will be of use in keeping a close eye over the wall." "That ought to stop the nonsense," Harry nodded.

"But I don't imagine that any further efforts to destroy the wall will be made tonight, anyway." "We'll have the night patrol out _every_ night after this," Tom declared.
"But I'm not so sure either, that another effort won't be made to-night, if we don't put a watch on to stop this wicked business.
