“Where would there be a bell around here?” asked Don.

“I don’t think that there is a bell nearer than the mines. I guess I must have imagined it, that is all. Well, it is growing dark. Shall we separate now?”

“Guess we might as well,” the others agreed.

With mutual goodbyes and agreeing to meet again at the grove in which they were at present stopped, the four boys split into two groups and went in opposite directions. Terry and Jim rode north and up the mountain, and Ned and Don began to make their way south, moving up the mountain on a gradual slant.

“Funny about that bell,” Ned said, as they rode slowly forward. “I could have sworn to it that I heard a bell ringing.”

“What kind of a bell?” asked Don.

“Sounded like a church bell, and it seemed to be tolling. But I guess it was some other sounds that I mistook. Certainly there is no church anywhere around here.”

“Doesn’t look as though there is,” grinned Don.

The sun had now set on the other side of the giant range and they were in total darkness. Knowing that it would be useless to push on very rapidly during the night they planned to put up a temporary camp on some ridge and wait there until daylight came. That would give them a few hours to look around before returning to their meeting place to compare notes.

“Guess we might as well camp and eat,” Ned suggested, and they found a spot that was dry and sheltered, where they speedily kindled a small fire and made some coffee. Sandwiches went with it and then they settled down beside the fire, talking quietly and keeping both ears and eyes open for any strange sound. It was early when they turned in and slept soundly.
