"That's what Mumps said," cried Sam, before he had stopped to think twice.

"Ha! So you have met Mum—I mean John Fenwick?"

"We met him on the river."

"And he said you had been following him?"

"Never mind, Mr. Crabtree, we won't talk any more," put in Dick, with a warning glance at Sam. He turned to the waiter. "Some fish, please, trout; and see that the biscuits are warm."

"Yes, sah," grinned the negro.

Tom at once took the cue. "It's going to be a warm day," he said to Dick.

"I wonder how sailing was last night," put in Sam slyly.

At this Josiah Crabtree looked as black as a thundercloud.

"You boys have been playing the sneak on me!" he cried. "Take my advice and beware of what you do in the future."
