"Naturally," agreed Professor Wright, smoothly. "Now that we have been made aware of your intentions we shall act accordingly. We shall be obliged to keep you under guard, but I assure you that if you do not act roughly neither will our guards. I am sorry you would not agree to our plan, and see matters in our light. It would have been so much more comfortable. And when we have explained, as we hope to do soon, you would appreciate our attitude."

"Well, all I can say now is that we don't appreciate it!" snapped
Nort, "and we'll leave at the first opportunity!"

"Then we'll see that you get no opportunities!" sneered Silas. "Let's take 'em out, Del!"

As it was evident that the two professors meant what they said, and that the boys would be roughly handled if they did not submit quietly, they followed their captors out of the dining tent, in answer to signals from Silas and the half breed that this was what was wanted.

"Here's going to be your stopping place," said Silas, with another sneer, as he stopped in front of a small tent. "And let me tell you it will be best for you to take it easy. You may get into trouble if you try to leave!"

To this Nort and Dick answered nothing. They were too angry to know what to say, but that they intended to submit quietly to this indignity was not in their natures. They cast quick glances about the camp before entering the tent, the flap of which Del Pinzo pulled back. The tent contained two cots and some small packing boxes for tables and chairs.

"All right!" said Nort, as he sized up the situation, and glanced back at the men who were his own and his brother's guards for the time being. "You can do your best to keep us here, and we'll do our best to get away. It'll be a fifty-fifty proposition!"

Nort was startled by an exclamation from Dick. The latter was gazing at some commotion on the far side of the camp. Looking out from the opened tent Nort saw being driven, along the bank of a small brook that ran through the swale, several big steers. They were being hazed along by Greasers on horses, and as the cattle splashed into the water, stopping to drink thirstily, the boy ranchers caught sight of the brands on their flanks.

It was the mark of the Diamond X ranch!
