As they skillfully guided the boat onward, striving to keep it headed with the tide, both heard distinctly, above the roar of the water and the grinding of the ice, a quick, dull noise strangely like the galloping of horses.

Vera heard it too, and started from her seat in alarm. All three forgot for a moment the nearer and more imminent peril, and turned for a look at the spot they had just left. The moonlight shone brightly on the cabin, and on the man and dog standing by the shore, and then its pale rays fell on foaming horses, and rifle barrels, green uniforms, and bearded faces, as a troop of Cossacks spurred at top speed around the bluff and out on the broad stretch of shore.

At sight of that dread body of horsemen they shivered and felt that hope was indeed gone. Sandoff was the first to fling off the lethargy of despair. His mental eye showed him what chances were favorable and what unfavorable. Besides, he would rather have died than submit to recapture.

“Don’t despair,” he whispered sharply to his companions. “We have a chance yet—and a good one. The country below us looks rugged, too rough for the Cossacks to traverse with any speed. If the current continues as it does now, we shall easily distance them. Help me to get the boat toward the other shore as far as possible, Shamarin; they may take it into their heads to fire at us.”

The latter obeyed unquestioningly, and with some trouble the boat was headed obliquely across the current. Then the terrific struggle began anew—the battle with the waves and the impetuous ice floes that constantly menaced the destruction of the craft and its inmates, only to be flung sullenly to one side by the skilled hand of Sandoff or Shamarin. Slowly the boat made headway toward the desired shore, and Vera cheered the men in their labors by timely words of encouragement.

But by this time the ferryman had given the Cossacks all the information they needed, and at the sharp word of command from their officer they spurred down the shore, unslinging their rifles as they rode, until a timbered bluff, jutting into the river, stopped further progress.

The boat was now well toward the other shore, and some distance down stream, but it was still within sight and range. Just as the fugitives dropped flat by Sandoff’s hurried command, a straggling volley was fired, and the leaden bullets plowed into the ice cakes and splashed in the patches of black water. But the boat was untouched. A moment later the current swept it around the curve, and the danger was past for the present.

“Now head it straight—straight with the tide,” said Sandoff. “There! That’s it. Let it take its own course now. All we need do is to keep it trim and fend off the ice.”

The Shilka was at this point less than a quarter of a mile wide, and the fugitives saw with delight steep ridges falling sheer into the water on each side of them.
