The guide nodded.

“Who is he?”

“Señor Lasar.”

“Lasar.  What’s his other name?”

“Juan not know.”

“Did they stop in the village?”

“No.  Señors get ponies, ride over mountain,” and the guide pointed lazily to the south-west.

“Where did they go?  Do you know?”

Juan shrugged his shoulders, indicating that he did not.

“What is Mr. Lasar’s business?”

Again the guide answered with a shrug.  He seemed disinclined to discuss the man in whom Tad Butler was so much interested.  Up to that time the lad had been too fully occupied with other matters to think of the conversation he and Stacy had overheard on the Atlantic and Pacific train.  Now it came back to him with full force.

“Know anybody by the name of Marquand in this country?” he asked, taking another tack.

Juan said he did not, and then Tad gave up his questioning.

“I was asking Juan about the two men who sat ahead of us in the train yesterday,” he explained to Chunky, as the fat boy joined them.

“Wha’d he say?”

“One is named Lasar, but he did not know the other one.  I can’t help believing that those fellows were plotting to do some one a great injury.”

“So do I,” agreed Chunky.  “I guess we had better not say anything about it to the others, but we’ll try to find out who this man Lasar is, and who Mr. Marquand is.  Then we’ll decide what to do next.”

Their further conversation was interrupted by the voice of the Professor, announcing that they would halt for their noonday meal.  All other thoughts left the mind of Stacy Brown when the question of food was raised.  He quickly slipped from his pony, running back to hurry the burros along so as to hasten the meal for which he was yearning.  Only one burro was unpacked, as it was the intention of the outfit to push on soon after finishing their lunch.

While the guide, under Ned’s direction, was making it ready, Tad and Chunky strolled off to climb a high rock that they had seen in the vicinity and which, they thought, might give them a good view of the plains to the southwest on the other side of the range.

They had promised to be back in half an hour, but circumstances arose that caused them to delay their return considerably.

After threshing through the bushes, over sharp rocks and through miniature canyons, they gained at last the object of their quest.  The distance had been further than they had imagined.

“We’ll have to make a short trip of it up to the top and back,” said Tad.  “It has taken us almost all our time to get here.  But we’ll have a look, anyway.”

They soon gained the top of the rock, which stood some twenty feet higher than the crest of the mountain on which it rested.

“Isn’t this great?” exclaimed Tad.

“Might think we were in the Rockies.”
