"We shall have to cross the river here," he said; "there is a ford, and the men will only be up to their waists in water."

And, giving the example, the old man stepped into the bed of the river. The others followed immediately, and, as the Scalper had announced, the water was only up to their waists. They passed threes in front, and closing up the ranks, so as to resist the rather strong current, which, without these precautions, might have carried them away. Five minutes later, the whole band was collected in the interior of the grotto, at the end of which was the secret door.

"The moment has arrived," the Jaguar then said, "to redouble our prudence; let us avoid, if it be possible, bloodshed. Not a word must be uttered, or a shot fired, without my orders, under penalty of death." Then, turning to the White Scalper, he said, in a firm voice—"Now, open the door!"

There was a moment of supreme anxiety for the insurgents, who awaited with a quiver of impatience the downfall of the frail obstacle that separated them from their enemies.


CHAPTER XV.

A THUNDERBOLT.

We will now return to the hacienda.

The Colonel and the Major-domo went down to the Patio, where they found assembled the one hundred and fifty men selected for the execution of the surprise, which the Colonel proposed to attempt on the rebel camp. Tranquil, according to the orders he had received, after assuring himself that Carmela was enjoying a sound and refreshing sleep, hastened to tell Loyal Heart and Black-deer what the Colonel expected from them. The two men immediately followed their friend into the Patio, where the soldiers were already assembled.

The Colonel divided his men into three detachments, each of fifty men: he took the command of the first, keeping the Canadian with him; Don Felix, having Loyal Heart for guide, had the command of the second; and the third, at the head of which was placed a captain, an old soldier of great experience, was directed by Black-deer. These arrangements made, the Colonel gave the order for departure. The detachments at once separated, and left the hacienda by three different gates.
