"Well, what was this work?" asked Dudley. "If the man scoffed at ranching, what else could there have been? Out here on the pampas there is little that one can do to earn a living except by looking after cattle."

Pepito turned to the dusky gaucho and questioned him closely. Then he swung round to his young leader and shrugged his shoulders.

"Our friend cannot say definitely, for even a gaucho in his cups has some caution. But this is certain. The forest belt which separates us runs far into the Indian country, and the man who owns this estancia has friends there. It seems that on occasion the Indians are invited to a feast, just to keep them in good temper, and our friend here believes that more than one Indian raid has been planned by this neighbor of ours."

The news came as a blow to Dudley, and for a while he sat his horse in moody silence, while Pepito and the other gaucho drew rein and retired at a wave of his hand.

"If the hint that we have just had has any truth in it we have trouble to face," he said at last. "If this fellow is a rascal, and makes friends with the Indians, he is now possessed of all the information he wants. He has heard of our forts, and of the agreement between the ranchers, and in that case he will be fully prepared. I think——"

He broke off suddenly, and pulled in his horse with a jerk.

"You think? Yes?" demanded Harold eagerly, for he too had gained an unfavorable impression of their last host.

"That it is my duty to look further into this matter. You see, these Indian raids are very dangerous, particularly for Mr. Blunt, for he lives right on the Indian frontier. Now if the fellow we have recently left is a rascal——"

"As Pepito's friend seems to believe."

"Exactly. If he is a rascal and harbors Indians it explains why these raids are so sudden and so successful as a rule. I noticed myself that in our last affair the men who invaded the estancia retired in this direction. I can see for what reason. They make for the nearest and most secure shelter. They retire on the forest, break up into small bands there, and each band drives off a lot of cattle, knowing well that they are secure, for they are on another estancia, and it is a rule amongst the owners not to bring their men on to a neighboring rancho."
