"No, sir; I heard about it to-night for the first time," answered Claus. "Banta is going up there to-morrow."

"Then we will know something about it when he comes back," remarked Bob. "I hope the boys have got the better of those ghosts in some way, and that they are working their mine. Go on, and tell us what you have heard."

Claus did not have much to tell, for the miners had cut the conversation short; but what little he did say created great excitement between those who heard it now for the first time. The boys had got the better of those unearthly spirits in some way, for if the ghosts had driven them out and not allowed them to work their mine, the miners would have found it out long before this time.

"I don't see why Banta put it off for two weeks," said Jake; "I reckon he was afraid of them spirits."

The next day was one which Claus often remembered. There was much excitement in the camp, although it did not show itself. There was none of that singing and whistling going on, but every man worked in silence. Banta and his partner had got off at daylight, and ten hours must pass away before they could look for their return; but evening came on apace, the camp-fire was lighted, and the miners gathered around it and smoked their pipes without making any comments on the long delay of Mr. Banta and the man who had gone with him. There was one thing that troubled them, although no one spoke of it—the mule which had carried their pack-saddle came home alone, and was now feeding in company with the old bell-mare. That looked suspicious, but the men said nothing. For an hour they sat around the fire, and then one of them broke the stillness. He was an old, gray-headed man, experienced in mining, and of course all listened to what he had to say. He spoke in a low tone, as if there had been a patient there and he was afraid to arouse him.

"Ten miles in ten hours," said he, knocking the ashes from his pipe. "Boys, something's got the better of those two men. I remember that several years ago I was waiting for a partner of mine who had gone away to prospect a mine——"

"What was that?" exclaimed a miner, jumping to his feet.

"I heard something, but I don't know what it was," said another.

It was done quicker than we could tell it. In less than a second two hundred men sprang to their feet, and two hundred hands slipped behind them and laid hold of as many revolvers. Of all those men, there was not one who would have hesitated to fight Indians with the fear of death before their eyes, but there was not a single instance of a miner who did not change color at the sound of a noise which seemed to come upon them from no one could have told where.

"Which way did the noise come from?" asked a miner.
