Far, far away on the icy shores of Kamchatka other Russian sentinels were keeping watch. The distance between the two frontiers was over six thousand miles as the crow flies.

And this empire, so colossal in extent, the very incarnation of military force, was threatening little Czernova, Barbara's own principality! There was no hope of her emerging victorious from the contest. The very idea was insanity. She would be but as an infant struggling in the hands of a giant. And the nations of Europe would look on unmoved, as they have often looked on and condoned the conquest of the Weak by the Strong. There was none to pity or help her. And as Paul thought of all this his heart grew hot within him. He began to feel something of the spirit that animated the Polish patriots of Czernova.

Suddenly the Cossack sentinel, catching sight of strangers, turned his horse's head in their direction, and lowering his lance, he came on at full speed.

On nearing the two friends he reined in his shaggy steed with such quickness as to throw the animal almost on its haunches.

"Your passport, little fathers?"

"Here is the universal passport, in Russia as elsewhere—cash," replied Trevisa, displaying some rouble-notes. "We come no farther, and are here simply to fight a duel."

"A duel! That's against the law of Russia. The guard-house is but half-a-mile distant among those trees yonder," said the Cossack, indicating the direction with his lance. "The captain is a terrible fellow. If he should come this way he'll order your arrest and mine too."

"Not he. He'll be only too pleased to witness a good fight. Besides, we have rouble-notes for him also. He has his price, I dare be sworn, otherwise he would be a novelty among Muscovites."

The Cossack reflected. A duel was a pleasant thing; a douceur still more pleasant. Why, then, seek to prevent the fight? He would take his chance of discovery at the hands of his captain. So having first looked cautiously round, he stuffed the rouble-notes into his left boot and made no more opposition.

"Let the Czernovese slay each other," he muttered. "The fewer for our Czar to fight when the talked-of war takes place."
