"We'll use one at a time--that will make 'em last," said Dave.

This was considered a good suggestion, and all but one of the flaming lights were extinguished. Then they walked down the pa.s.sageway as quickly as safety permitted.

"I--I don't see anything that looks like what I saw before," said Roger, after a bit. "The rocks look all alike to me."

"An' to me," returned the old miner, and there was something of hopelessness in his tones.

But they kept on. Dave had the torch and was ahead, with the others close at his heels. The single torch gave but an uncertain light and cast grotesque shadows on all sides.

"Look!" cried our hero, a little later.

He pointed to a series of small stones resting on the floor of the cavern. They were somewhat in the form of a circle, with a large stone in the center.

"Oh, I remember those stones!" cried Roger, joyfully.

"So do I!" put in Abe Blower. "I reckon as how we are in the right pa.s.sageway now, lads!" he continued, in a more hopeful tone.

"I am sure we are!" came from our hero. "But we have a pretty good distance to go yet."

"Yes, an' be careful thet ye don't go down in none o' them pesky holes,"

cautioned the old miner.

Quarter of an hour later they reached the spot where they had shot the lioness. Looking ahead, they saw a torch waving in the air.

"Hullo! hullo!" came in the voice of Phil. "Where are you?"

"Here we are!" answered Dave and Roger.

"You've been a long time in here," went on the shipowner's son.

"We got lost," announced Roger.

"And we shot the mate of that mountain lion," added Dave.

They soon reached Phil, and then the whole party quickly made their way out of the cave. Those who had been left outside listened with interest to what Dave and the others had to relate.

"Well, that sure must be some cave!" exclaimed Tom Dillon. "An' as Abe says, we must come back and examine it more closely some time. There may be a lot of gold an' silver in it, an' maybe other metals."

"Perhaps radium!" cried Phil. "Say, wouldn't it be great to find a radium mine!"

"I don't think ye'll find any o' thet new-fangled stuff here," answered Tom Dillon. "An' anyway, gold an' silver is good enough for me," and he smiled broadly.

Nightfall found the party still among the loose rocks that overspread the mountainside where the great landslide had taken place. Looking at the forsaken and desolate region, the boys could well understand why the search for the lost mine had been given up. There was nothing to be seen that looked in the least promising. Rocks and dirt rested on all sides, and that was all.

"We looked over the rocks and the dirt putty well, too," explained Tom Dillon. "But there wasn't nary a sight o' gold; eh, Abe?"

"Not enough fer to buy a plug o' tobaccer with," answered the other miner.

As one spot was no better than another apparently, they did not spend much time in looking for a place to camp. In one place was a little rough brush and here the horses were tethered. Then a tiny fire was kindled in a hollow of the rocks, and over this they prepared their supper,--a rather slim affair, considering that every one was tremendously hungry.

"Not a seven-course dinner," said Phil, with a sickly grin.

"Never mind," returned Dave, cheerfully. "Just wait till after we have found that lost mine and get into Yellowstone Park. I'm sure the hotels there serve the best of meals."

"O dear! now I am here, it doesn't look so easy--I mean to locate that mine," sighed Roger.

"What, you're not going to give up so soon, are you, lad!" cried Tom Dillon.

"Why, we ain't begun no search yit," added Abe Blower. "Time to git kind o' tired arfter ye have been here a week or two an' nuthin' doin'."

To this none of the boys replied. But they could not help but think what a dreary time it would be, searching among those rocks and that loose dirt day after day, if the lost mine were not brought to light.

The day's exertions had tired all hands, and they slept soundly throughout the night, with nothing coming to disturb them. When the boys got up they found Abe Blower already at the campfire, preparing a breakfast of his favorite flapjacks and bacon. He fried his big flapjacks one at a time in a pan, and it was simply wonderful to the boys how he would throw a cake in the air and catch it in the pan bottom side up.

"It's the knack on't," said Tom Dillon, as he saw the lads watching the feat performed. "I know some old miners kin keep two pans a-goin' that way, and never miss a cake."

"I'd like to try it," said Phil.

"Not now--we ain't got no batter to waste," replied Abe Blower, with a chuckle.

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."

"You mean to get above the rocks and roll 'em down the mountainside, one after another?" questioned Tom Dillon.

"Exactly, Tom. We could do it with the wust o' the rocks that are loose--an' the rest wouldn't matter so much."

"But we'd have to take care that we didn't roll the rocks on somebody's head," remarked Dave.

"To be sure."
