Roldan and Adan looked at each other. The latter's face had paled. Roldan contracted his lids suddenly, and when his friend met the glance that grew between them he compressed his lips and involuntarily straightened himself: he knew its significance.
"We must cross," said Roldan. "It would never do to spend the night on this side. If they followed, they would never suspect us of crossing. If we remained here, we could not hear them until they were upon us."
"Very well," said Adan.
Roldan raised his bridle. The mustang did not move forward, but cowered. "I don't like to hurt horses," said the young don, "but he's got to go." He clapped his spurs savagely against the animal's sides, and the next moment the waves were lashing about him.
Adan was beside him at once, and together they breasted the rushing waters. The mustangs were strong and made fair headway, incited by terror and the spur. The water was very cold, but the boys scarcely felt it. Their eyes were strained toward the opposite shore, measuring the distance, which seemed to grow less very slowly. The stars were thick and the moon was floating just above the chaparral, but the darkness about them was grim, and only a narrow line of white indicated the shore.
The horses were not able to keep a straight course. The current lashed them about more than once, but they righted, shook the water from their quivering nostrils, and plunged on.
The boys' glance so persistently sought their haven that they saw nothing of what was passing about them. They were within twenty yards of the shore. Adan, having the stronger beast, was some little distance ahead. He did not observe it. He was registering a vow that if he reached land in safety he would be drafted every year of his life before he would ford another river after heavy rain.
Suddenly Roldan became conscious that the wiry little body between his gripping knees had relaxed somewhat the tension of its muscles. Was the poor brute collapsing? Roldan leaned over and patted his neck. It responded for a moment, then fell back again. Roldan set his lips. As he did so he cast about him the instinctive glance of those in peril. A huge log was bearing down upon him like a projectile.
In a second his feet were out of his stirrups and he was crouching on the mustang's back. The log struck the beast full in the side, tossing Roldan as if he had been a feather. The mustang gave a hoarse neigh, unheard above the roar of the water.
Roldan, keeping his face from the pounding waves as best he could, struck out for the bank. But the current was too much for his slender body, plucky as it was. He made a mighty effort and shouted,—
