"He looked to me like a man I have seen in New York," said Fremont. "I wonder if there is any one left in New York?" he added, with a grin. "It seems to me that about all the people I ever knew there are on their way south."

"This fellow may be fascinated by our good looks," Frank put in. "He seems to be in need of polite society."

"Polite society!" repeated Jimmie. "You give him a dump on the floor for polite society. Is he the man who is lookin' for the mine youse fellers have been talkin' about ever since we left El Paso?"

"If we should follow him to the mine," George suggested, "and arrest him there, that ought to end the case. It would end the mystery, anyway, and show why the assault was made. I guess you have been after this man all the way down, Nestor," he added.

"When he hasn't been after me," laughed the patrol leader. "But you mustn't be too certain that the arrest of this man would end the case. He may be after the mine, may even have a copy of the description in Mr. Cameron's office, and yet be entirely innocent of the crime."

"He ought to be pinched for trying to geezle me in the eats house," grinned Frank.

The boys ascended the slope until darkness set in, and then rested in a little valley, or dent, between two peaks, and pitched their two small shelter tents. Then they built a fire of such light wood as they could find and prepared supper. As soon as the meal was cooked they put out the fire, fearful that the smoke might betray their presence there. Presently Jimmie called attention to two columns of smoke rising high up on the mountain.

"They're signals," he said, "because there wouldn't be two camp-fires close together. They're signals, all right."

"What do they mean?" asked Nestor, with a smile.

"One column means come to camp," replied Jimmie, "two mean that help is needed, three mean that there is good news, and four mean come together for a council. They are Indian signals, and the Boy Scouts use them in the woods when out hunting."
