The morning meal at an end, the hunt for traces of the lost Landslide Mine commenced in earnest. Dave and his chums had come dressed for the work, and the whole party were provided with picks, shovels, crowbars, axes, and a couple of gold-pans.

The whole of that day was spent on the mountainside, the various members of the party separating from time to time and then coming together, to relate their various experiences. The old miners had told the boys how to search and what landmarks to look for, so that they did not seek altogether blindly.

It was hard, hot work, for the sun poured down all the long day. And added to that, water was scarce, for the nearest spring was well down the mountainside, and even this had a bitter taste which rendered it far from palatable.

"Well, nothing doing so far," said Roger, as they came together in the evening.

"Never mind, we may have better luck to-morrow," returned Dave, as cheerfully as he could.

Several days went by, including Sunday, and still they found nothing that looked like a trace of the lost Landslide Mine. They had covered a tract of rocks and dirt several hundred feet in width and all of half a mile long. The only spot they had avoided was one where some loose rocks looked to be positively dangerous.

"We might tackle that, but we'd be taking a big risk," said Dave.

"Right you are," said Phil. "If those rocks tumbled on us, it would be good-by to this world!"

"But the entrance to the lost mine may be under those very rocks!" sighed Roger. "And if so, just see what we'd miss by not searching there."

"I've got an idee fer tacklin' thet place," said Abe Blower. "It will be hard work, but putty safe—if we are careful."
