They were proceeding carefully, conversing, and noting the interesting relics of a bygone civilisation, when, without a word, Drake suddenly seized his companion’s arm and hastily dragged him behind a convenient wall. Frobisher, too much astonished for words, could only look round, wonderingly, imagining that the pirates were after them again; and as he did so, he perceived the cause of the skipper’s alarm.

The danger was not behind, but in front. The pirates had proved to be wider awake than either of the Englishmen had anticipated, and had posted a sentry at the eastern gate. Fortunately for them, the man happened to be looking in another direction at the moment when they turned the corner, or discovery would have been inevitable. As it was, the question arose—how was this fresh obstacle to be overcome? They might possibly avoid the man by making a long détour to some other gate, but this plan appealed to neither of them, for even should they succeed in escaping by some other outlet, the ground outside the walls was so bare that the man must inevitably see them. The alarm would be raised, when of course the pursuit would at once be resumed, and their capture become certain.

A few words between the two Englishmen sufficed to show that the same plan—the only practicable one—had occurred to both; and, avoiding the main street, they made their way through side lanes and back alleys until they emerged at a spot only a few yards distant from the unsuspecting sentinel. Then, watching through a convenient cranny until his back was turned, they ran swiftly forward and concealed themselves behind a low stone wall which the man was passing and repassing on his beat.

The next time he passed that wall the sentry experienced the unpleasant sensation of being jumped on from behind by two men, one small and the other very large and heavy; the latter kneeling on his chest and squeezing his windpipe, while the other securely lashed his wrists and ankles together with strips torn from his own robe, their operations being completed by thrusting a gag made of the same material into his mouth and securing it there firmly. The Englishmen then carried him between them into one of the adjacent ruined houses, took him to an upper room, and left him there for his companions to find, if fate should so decree.

As a matter of fact, fate evidently decreed against the unhappy man, for several months afterwards the remains of a gagged and bound Chinaman were found in that very house by a party of travelling nomads; but it was a case of the pirate’s life or those of the Englishmen, and it did not take them long to decide which the world could best spare.

The sentry having been thus disposed of, Drake and Frobisher struck off across the desert, by the margin of the river, at a good round pace; for since the pirates had posted a guard, it was probable that they would visit him sooner or later, and the Englishmen wanted to be well out of sight before anything of that sort should occur.

A little later on they were fortunate enough to come to a village, most of the inhabitants of which were away, as it happened, probably hunting, or fishing, or otherwise engaged upon their usual occupations. Here they secured a hearty meal of rice, bread, cheese, and goats’ milk; after which they found themselves marvellously refreshed, and thought the meal cheap at the price of one of Genghiz Khan’s gold pieces, specially cleaned up for the purpose of payment.

It is unnecessary to relate in detail the incidents of the journey of the fugitives back to Tien-tsin, for nothing in the way of real adventure occurred after they had once left the ruined city behind. On the way Drake explained to Frobisher how he had come to attempt his friend’s rescue; and, in a few words, this is how it came about.

Drake had returned in the Quernmore from England with his cargo, which he duly delivered. Then, as China was purchasing steamers for use as transports, and he was offered about twice his ship’s actual value, he sold her, and so found himself at a loose end, without employment. He regarded this as a favourable opportunity to commence enquiries respecting Frobisher, whom he believed to be still a prisoner in Korea; and, happening to encounter Wong-lih—who had by that time returned from his visit to southern China—he heard the whole of Frobisher’s history, from the moment when the admiral found and rescued him at Asan, to that of his expedition up the river after the pirates. He was also informed that the expedition had failed, and that his friend was either dead or a prisoner. Wong-lih, said Drake, was greatly cut up at losing so promising an officer, a man, too, of whom he had made a friend; but he could not be induced to send a rescue party. He was altogether too busily occupied with matters of moment to his country, and war was so imminent, that, as a matter of fact, the admiral found himself absolutely unable to spare a ship or a crew for such a purpose. Drake therefore determined to ascertain for himself if Frobisher were still alive, and, if so, to attempt his rescue. And as he happened to be a good Chinese linguist, and possessed in a high degree the art of disguising himself, the attempt proved, as has been seen, completely successful.
