"Sure we will!" asserted Snake, but he and the other cowboys, more experienced in matters of this sort than our heroes, felt that there was a grim terror between them and those whom they pursued.

However they had started, and were making as good time as possible. Messages had passed between Mr. Merkel and those in authority at La Nogalique, and the probable route of the kidnapping Yaquis was indicated as well as could be. This saved a long trip to the border in order to get on the trail of the Indians from the time they had taken Rosemary and Floyd.

Well armed, with righteous indignation burning in their hearts, used to roughing it, and with men who knew almost every foot of the country, the expedition from Diamond X was well equipped for the work in hand.

At first after they started out there was eager talk, and speculation as to where the Indians would be met with, and what the probable outcome would be of the fight that was sure to follow.

"Unless they run off when they see us and leave Rosemary and Floyd for us to bring back," spoke Dick, almost afraid lest this outcome should prevent a fight.

"Don't worry. They won't run! They'll stand and give us as good or as bad as we can send," declared Rolling Stone.

"We'll wipe out the band if we get half a chance!" declared Bud, and it was not said in a bloodthirsty or boastful spirit. It was calm retribution that actuated our friends.

Along the trail they traveled—a trail they were destined to follow for weary days and nights. This was only the beginning. They must make all the speed they could, and yet spare the horses all that was possible. There was a chance of getting new mounts at several places, but it was only a chance and could not be depended on. They must save what they had, both in the way of horseflesh and rations.

Night found them well on their way, and though the boys were eager to continue, Snake insisted on a halt being made not only for supper but to give men and horses a needed rest.

"The Indians will have to stop just as we do," said the older cowboy.
"They can't keep on continually; they have to stop and rest."
