Pedro called out something in Spanish, but there was no answer, save that one of the horses lifted its head and neighed.

Then Frank tried it in English:

"Ho, the camp! Who is there, and where are you?"

Almost instantly a man's voice replied:

"I'm out hyar whar I kin take a peep at yer, as I heard yer comin'.

Didn't know but you wus Greasers, an' I ain't got no use fer ther onery varmints. As yer kin talk United States, just move right up ter the fire and join me at supper."

There was a hearty freedom about the invitation that dispelled Frank's fears immediately, and they rode forward into the firelight.

As they did so, a man rose from where he had been stretched on the sand, and came forward to meet them.

"Great Scott!" shouted Frank, as the firelight fell on the man's face.

"It's Alwin Bushnell, Jack Burk's partner!"

CHAPTER VIII.

THE TREASURE SEEKER.

"Thet thar's my handle," acknowledged the man; "but I'm strapped ef I understand how you 'uns happen ter know it!"

He stared at the boys and the guide in blank amazement. Seeing Pedro's face fairly, he gave a slight start, and then looked still more closely.

"There's no doubt," palpitated Frank; "you are Alwin Bushnell?"

"That's me," nodded the camper.

"And you are alone?"

"Certun sure."

"Bound west?"

"I reckon."

"For the mountains and the Silver----"

Frank caught himself, and stopped short, remembering Pedro, and knowing the guide's ears and eyes were wide open to hear and see everything.

Bushnell fell back a step, a look of still greater surprise coming to his bronzed and bearded face.

"W'at's thet thar you wus goin' ter say?" he demanded.

"Wait," said Frank, "I will tell you later. It is better."

Plainly, Alwin Bushnell was puzzled, and not a little amazed.

"You know my handle, an' you seem ter know whatever way I'm trailin'.

This yere lays over me, as I acknowledges instanter."

"That's not hard to explain."

"Then I begs yer to explain it without delay."

"Your partner told us of you."

"Old Jack?"

"Yes."

"When, and whar?"

"Two days ago, outside of Mendoza."

"He wuz thar?"

"Yes."

"But how did yer know me?"

"We saw you."

"When?"

"When you were pursued across the plain by bandits."

Bushnell slapped his thigh.

"Thar!" he cried; "I remembers yer now! You wuz near a doby hut, an' yer opened up on ther pizen skunks as wuz arter me."

"That's right."

"Wall, I'm much obliged, fer you socked ther lead ter them critters so they switched off an' let me get away. You kin shoot, boy."

"Some."

"Some! Wa'al, that's right, you bet! Give us a wag of your fin! I'm mortal glad ter clap peepers on yer, fer I never expected ter see yer an' thank yer fer thet trick."

Frank swung from the saddle, and surrendered his hand into the broad "paw" of the rough and hearty Westerner, who gave it a crushing grip and a rough shake, repeating:

"I'm mortal glad ter see yer, thet's whatever! But I want ter know how you happened to chip inter thet thar little game. You took a hand at jest ther right time ter turn ther run of ther cards, an' I got out without goin' broke."
