There was a burst of flame through a cloud of smoke, out of which Stan—fascinated into looking out—saw something alive flaring as it rushed here and there, making for a party of its fellows dashing up with more of the pots.

It was all done in a few seconds, and had any of the assailants been ready and noticed the lad watching, he would have been shot down. But every eye was directed at the blazing figure, and, to his horror, Stan saw the end of the tragedy. For the instinct of self-preservation had made them doubly callous to their comrade’s sufferings. The man rushed on as if seeking help or in a blind effort to reach the river and plunge in; but he did not reach it of his own volition, being received upon the lowered spears of three or four of his comrades, and then he was thrust, shrieking horribly, over the edge of the wharf, a sullen puff of smoke from the surface of the water telling that the tragedy was at an end.

A frightful sensation of sickness made Stan’s head swim as he dropped back to the floor just in time to escape being struck by another of the fiery missiles; but the faintness was driven off by excitement, and it was with perfectly clear brain that the lad saw the burning Asiatic grenade hurled back amongst the yelling assailants. This proved to be with an effect that checked further effort for the moment and sent two of the pirates running to the edge of the wharf, to plunge in and climb out again dripping, but with no worse injury than a few smarting burns.

Stan was awake to the danger that was rapidly increasing, for after seeing that the smoking patches of pitchy resin on the floor were innocuous, he ran on towards where the far end of the great room was full of smoke, dreading greater mischief there; but, to his great relief, he found that, though quite half-a-dozen stink-pots had been hurled in through the windows, the coolies there had dashed them back at once. And here, too, he found that the enemy had suffered so painfully from their own weapons that the throwing had ceased.

Any doubt that might have lingered in the brains of the British defenders respecting the amount of confidence that might be placed in the Chinese labourers was now completely driven away; for though the men had been burned about the hands by the missiles they had returned, they made very light of the pain, laughing and congratulating one another upon the retaliation they had been able to inflict, for Stan soon gathered that here no less than three of the enemy had been seen to rush shrieking to the edge of the wharf and plunge in.

There was a brief cessation now from the attack, and the defenders, whose vision was a good deal obscured by the smoke that hung in the place, made out that the throwers were hanging back from where several stink-pots were burning away in the shelter of the wall, some of the men protesting loudly as one of their leaders furiously urged them on, and ended by trying to set his followers an example by stepping forward, seizing one of the vessels, coming back into sight again with the pot flaming as he held it by its loose handle, and then making a rush to a breach where a portion of the tea-chest wall had been torn down.

The act was one of barbaric bravery, and Stan saw him reach the top, swinging the pot to and fro and making the flames roar as they rushed away from his hands. Then as his arm was reached out backwards to its fullest extent, and he was about to launch the horrible missile at the opening in front, there was the sharp crack of a rifle, and he fell forward, pitching headlong to the ground beneath the window, while the blazing pot struck the stonework close to the foundation of the building, broke up, and went on blazing and sending up a dense cloud of pitchy smoke.

“Dead?” said the man who had fired, for Stan had reached forward to look out, but drew back again coughing.

“It’s impossible to see,” he cried. “The smoke is blinding.”

“And it will be setting something on fire,” said another voice out of the smoke.
