Suddenly Jack thought of the telephone. He ran back into the hut and telephoned the glad news of the safety of the dam to the amazed office in Maguez. Also he gave them a brief sketch of what had happened.

"But what the——" came a brief voice at the other end, but already Jack had rung off and was outside, where Jim Hicks and Coyote Pete had the ponies.

They had held a hasty consultation, and had decided that inasmuch as the soldiers were advancing on the mission, and the American ranchers were on their way, that their best plan would be to head back toward the valley. But it was Jack who vetoed this plan.

"I want to be in at the finish of those rascals," he exclaimed, "and, besides, think of our friends imprisoned in that dismal old church."

"You're right, kid," shouted Coyote Pete, waving a dripping hat in the downpour, "the mission it is."

Old Simmons had been too badly shaken by his encounter with the Mexican for it to be advisable to leave him alone. Maud's pack was therefore removed, and the old dam-tender mounted on her. First, however, a call was sent for a "relief." Till the latter arrived the sluices were to be left open to drain off the heavy surplus of water.

"Wished I knew where them greasers' horses were," sighed Jim Hicks; "they'll be coming to in a minute, and walkin' bein' a healthy exercise, I'd like to provide some of it for them."

A short distance down the trail they found the miscreants' ponies, just as Ramon had left them hitched. Even the fair-minded Jack did not protest when Coyote Pete and Jim Hicks, with yells of glee, cut the cayuses loose and sent them galloping off.

"I only wish we could be here to see the Mexicans' faces when they wake up and wonder what's hit 'em," said Jim, who had examined each of the stunned men and ascertained that not one of them was seriously hurt.

"Now, then, forward!" cried Jim, as soon as the clatter of the retreating Mexican ponies' hoofs had died out.
