"I tell you, Jack, if the dirt you send up weighs as much as these ghosts did, the one who pulls it out will have the hardest part of the work," said Julian. "Now let us sit down and take a good look at them."

The longer the boys looked, the larger seemed to grow the animals that had created so great an uproar in the country for miles around. They regretted they had not brought a tape-line with them, that they might take measurements; but they came to one conclusion—if they found an animal like either of those in the mountains, they would give it a wide berth. They had read of encounters with them by men, and during their stay in Denver had listened to some thrilling stories, told by miners, of their fierceness, and they decided that those men had more pluck than they had.

"Let us take the skins off, and by that time it will be night," said Julian. "We can fill up the hole to-morrow."

"I don't know how to go to work at it—do you?" asked Jack, taking off his hat and scratching his head. "I never did such a piece of business in my life."

"We are not going to take them off with the intention of selling them; we are going to show them to the miners. If we tell them our story without anything to show for it, they will think we are trying to shoot with a long bow. If we make a few holes in the skins by a slip of our knives, who cares?"

The boys went to work on the cubs first, one holding the hind legs and the other doing the skinning, and they got along so well with them that they went to work on the big ones with more confidence. By the time it grew dark the skins were removed, and the carcasses were dragged away and thrown into the ravine. Then the boys began supper with light hearts. The mystery of the haunted mine had been unearthed, and Julian and Jack were ready to dig up the treasure—that is, if there was any there waiting for them.

CHAPTER XXIV.

"THAT IS GOLD."

"Jack, come up here; I have something to show you."

"What is it? Have you made yourself rich by washing out the last bucket of earth I sent up?"
