The boys promised to watch the passage faithfully, and the others passed on down the gangway, flashing their lights in every direction and making no pretense of moving quietly.

"Look here," Jimmie said after they had proceeded some distance into the mine and discovered nothing of importance, "I have in my possession a great idea! Want to hear about it?"

"Sure!" laughed Will.

"We're making too much noise."

"Making too much noise in order to attract the attention of a couple of lost youngsters?" asked Elmer.

"They're not lost!" insisted Jimmie. "They've been lured away or dragged away! We don't know how many men were in the mine with Ventner!"

"Well, produce your idea!" Elmer exclaimed.

"Well, my notion is that I ought to go on ahead of you boys, walking as quietly as possible and without a light. If there are people waiting to snare us, they'll naturally think we've bunched our forces and are all coming along together. Then, you see", he continued, "I'll be right in among them before they suspect that we have a skirmish line out."

"That's an all right notion, kid!" answered Will.

"Then I'll be on my way," Jimmie replied. "And if I need help at any time, I'll give the call of the pack!"
