At nine o’clock the next morning one of the two new men, who had been looking keenly ahead for a few moments, came up to Frobisher and pointed out what appeared to be a large, square, stone-built castle, or fort, standing some distance back from the river bank, upon the top of a knoll of rising ground.
“That,” he announced, “is the pirates’ head-quarters. There is a little bight just at the junction of the old and the new channels, and it is there that they lie in ambush with their junks. Now, sir, you can perhaps see their masts standing up behind that low bank yonder?”
Frobisher looked, and counted, indeed, five masts. They were, then, evidently those belonging to the pirate junks which had attacked the Chinese merchantman on the preceding day; and the fort on the hill, yonder, was the pirates’ lair which he had been specially dispatched from Tien-tsin to destroy. He rubbed his hands gleefully and gave orders to clear for action; then, with his telescope fixed unwaveringly on the fort, he leant over the bridge rail, watching, while the Su-chen, her engines working at full pressure, stemmed the muddy tide on her errand of retribution.

Tchen-voun-hien.
The Su-chen was about five miles away when the fort first came into view, and for about a quarter of an hour she steamed ahead without any sign of life or of alarm becoming perceptible in the vicinity of the pirates’ head-quarters. Frobisher was beginning to hope that fortune was so far favouring him that perhaps the freebooters might have set out on some buccaneering expedition inland upon this particular morning, and that he might thus be able to land, seize and destroy the junks, and occupy the fort during their absence; at the same time preparing an unpleasant little surprise for the pirates when they returned.
But his hope was doomed to disappointment. Still keeping his eye glued to the telescope, he suddenly observed a flash and a puff of white smoke leap out from a corner tower of the fort, and a few moments later the dull “boom” of a fairly-heavy gun made itself heard. At the same moment a tiny ball soared aloft to the head of the flagstaff on the battlements, which ball presently broke abroad and revealed itself as a large yellow flag of triangular shape, the apex of the triangle, or fly, being circular instead of ending in a point. There was also a design of some description embroidered on the flag in the favourite Chinese blue, but what the design represented Frobisher could not imagine. He had never beheld anything like it in his life, so he turned to Quen-lung, who was, as usual, standing alongside him, and, handing him the telescope, told him to take a look at the piece of bunting and say what the decoration on the flag was intended to represent.
Quen-lung obediently placed the eyepiece to his eye, and a few seconds later Frobisher observed the man turn pale and stagger backward, almost dropping the telescope as he did so. The man’s eyes were dilated, his face turned the colour of putty; his lower lip had dropped, and his hands were trembling as though palsied. He presently recovered himself, however, and the colour gradually returned to his face. Frobisher asked what ailed him.
