"The Barnaby Winthrop I mean had an undeveloped gold and silver mine he wished to open up."
"It was our uncle, beyond the shadow of a doubt," said Chet. "Our name is Winthrop, and Uncle Barnaby is our guardian. We can prove it to you by the papers, if you wish."
"I am willing to take your word, boys. But, you understand, one must be careful about speaking of mines in this section; at least I have been told so."
"Yes, we know about that," returned Paul. "Many a man has lost the chance of his life by advertising his knowledge too broadly. Others would gain a clew of a mine, hunt it up, and put in a claim before the original discoverer knew what was up."
"Exactly, and that is why I was slow in saying anything. But when you ask me to tell you about your uncle, I am sorry to say I know but very little, although I suspect much, now you say he has been missing so long."
By this time the little party had reached the ranch house. They went inside, and despite the fact that the boys were impatient to hear what Noel Urner might have to say, they gave the young man time to wash up and make himself otherwise presentable, Chet in the meanwhile frying another fish and preparing a pot of coffee.
"This is just what I wished, and no mistake," said Noel Urner, as he set to with a hearty good will. "But I am sure you are impatient to learn something of your uncle, so I will not keep you waiting. To make my story plain, I will have to tell you something of myself also.
"In the first place I am a broker and speculator from New York city. I make a specialty of mining stocks, and own shares myself in half a dozen mines.
"About ten weeks or so ago I heard through a friend in San Francisco that Barnaby Winthrop was trying to form a company to develop a new strike in this vicinity. I wrote to him and he sent word back that if I would come on he would prove to me that he had a big thing, well worth looking into.
"I had other business west, and so at once started for San Francisco. Your uncle had given his address as the Golden Nugget House, a place I afterward learned was frequented by old-time miners and prospectors.
"I made inquiries at the Nugget House for your uncle, and to my astonishment learned that he had disappeared very mysteriously one night, leaving no trace behind him."
"What!" cried Paul, springing to his feet, and Chet was too astonished to speak.
"I do not wonder that you are astonished. Yes, he had disappeared, leaving his valise and overcoat behind him.
"I thought the matter so queer that I was on the point of notifying the police. But on calling at the post office for letters I received one from him stating that he was sorry, but he had come back to the place in question and found it not what he had anticipated, so he wouldn't bother me any more."
"I don't believe he came back!" ejaculated Chet. "If he had he would have stopped at the ranch."
"I agree with you."
"Have you that letter?" asked Paul, his voice trembling with excitement.
"I have."
"I would like to see it, please."
"Certainly." And Noel Urner brought forth a large flat pocketbook from which he extracted the communication in question.
Paul took it to the light and examined it closely.
"This is a forgery! Uncle Barnaby never wrote it."
"Let me see, Paul," ejaculated Chet.
He also examined the letter with as much care as his brother had displayed. There was not the slightest doubt of it. The letter was not genuine.
"It's certainly a bad state of affairs," said Noel Urner. "It makes the disappearance of your uncle look decidedly bad."
"It looks like foul play!" cried Paul. "Why should Uncle Barnaby leave the hotel in that fashion if all was perfectly straight?"
"It's like as not some mining town rascals got hold of his secret and then put him out of the way, so that they might profit by it," said Chet. "There are plenty of fellows mean enough for that."
"At first I was satisfied by the receipt of the letter," continued Noel Urner. "But the more I thought over the matter the more I became convinced that something was wrong; but in a different way from what you think. I imagined your uncle had found other speculators to go in with him and they had persuaded him to cut me off. That is why I started off, after settling my other business in California, to find your uncle and learn the truth. I was willing to lose a few weeks' time out here looking around, even if it didn't pay."
"We are very glad you came and that we found you," answered Paul. "I am sorry for only one thing, that Allen is not here to meet you."
"I am in no hurry to continue my journey; indeed, I do not see how I can without a horse. If you wish I will remain here until your brother returns."
"You are right welcome to do that," cried Chet. "As for not having a horse, you are no worse off than ourselves, for we are without an animal of any kind, outside of the cattle."
"Then, being equally bad off, we ought to make good friends," smiled Noel Urner. "I shall like staying on a ranch for a few days first rate, and you can rely on my giving you all the assistance in my power when it comes to finding out the fate of your uncle."
"We can't do anything until Allen returns," sighed Paul.
"Then we will hope that your brother returns speedily, and with good news."
"The best news will be his return with all our horses," returned Chet. "We can do nothing without our animals."
Alas! How little did both Chet and Paul dream of the terrible ordeal through which Allen was at that moment passing!
CHAPTER VI.
From One Peril to Another
"I am lost! Nothing can save me!"
Such was the agonizing thought which rushed into Allen Winthrop's mind as he felt himself plunging madly downward to the glittering waters far beneath him.
It must be confessed that the otherwise brave young ranchman was fearfully frightened at the dreadful peril which confronted him. He and his faithful mare were going down, and certain death seemed inevitable.
"Heaven help me!" he murmured to himself, and shutting his teeth hard, clung grimly to the saddle.
Out of the sunlight into the gloom and mist below descended horse and rider.
Scarcely two seconds passed and then, with a resounding splash, the animal and its living burden disappeared beneath the surface of the river and out of the sight of the rascals on the opposite side of the canyon.
"That settles him," cried one of the horse thieves, grimly. "He was a fool to follow us."
"Maybe he'll escape," ventured a second.
"Wot! Arfter sech a plunge?" returned the first speaker, sarcastically. "Wall, hardly, ter my reckonin'."
They shifted their positions on the brink of the opening, but try their best, could see nothing more of the young man or the mare.
It was now growing darker rapidly, and fifteen minutes later, satisfied that Allen had really taken a fall to his death, they continued on their way.
And poor Allen?
