"Watch and watch, Li Fu," said Barnes, when night settled down on the islet, the river-mouth and the booming surf. "I'm done in. Wake me at midnight; they'll not come until then."  
"Not then, I think," said Li Fu. "China boys not like night devils. Plenty devils in liver."
 
"All right," Barnes laughed as he stretched out in the warm sand. "Let the river-devils fight for us, then!"
 
About midnight the quartermaster wakened him. There had been no alarm, no sound or sight of the enemy. Only the continuous rolling crash of the surf, regular and unceasing, conflicted with the noises of nightbirds from the jungle. The starlight and thin glow of the sickle moon faintly illumined the white sands and the glittering waters, where the waves curled and broke in running lines of phosphorescent radiance.
 
At first Barnes found Li Fu's conviction incredible. It was hard to believe that Lim Tock's lascars and Chinese, the latter probably predominating, would relinquish the opportunity to sweep in upon the islet with their boats and finish everything with one determined rush. The Chinese firmly credited the existence of water-devils, however, and river-devils in particular, whose power at night was invincible.
 
Barnes sat through his lonely watch, stiff and aching from his wound, and found no indication of alarm out on the surging waters, where a heavy ground-swell kept the rollers tumbling in along the shoreline. He began to think that he had wasted himself, despite all. Had he stayed in the boat, it by this time would be far up the river.
 
He laughed and shook off the thought. After all, he had no assurance of that! The boat, with only two oars, might be a day or two in reaching the main river above the delta, where the Dutch post would be placed. With dawn, the pirates would sweep down on the island. If they found it deserted, they would go up the river with a rush. No, the effort was not wasted; was far from wasted!
 
Toward dawn he roused Li Fu, and lay down once more to get all the rest possible. When the quartermaster again wakened him, it was to point out dark dots on the waters, now overcast with the graying dawn. The boats, four of them, were scattered a quarter-mile from the river mouth, up and down from the bar. Jim Barnes laughed softly.
 
"They think we'll come out with the first breath o' wind; that we've been waiting here for the breeze! And they're waiting to riddle us with their rifles, then close in. Good! Let 'em wait. Every minute gained puts the whaleboats farther up the river. Suppose we make some tea, Li Fu. The fire will show that we're here and encourage 'em to wait."
 
Chuckling at all this, Li Fu gathered wood and soon had a fire going. Hot tea and biscuit invigorated Barnes hugely, and he was much himself again by the time the reddening dawn and freshening daylight betrayed to the waiting boats that the fugitives were not setting forth from shore. No doubt they considered that Barnes had laid up the whaleboat and was prepared to fight it out.
 
"They're closing in," said Barnes suddenly. "Oars are out. The junk is coming down the coast, too. She'll probably anchor off the river, and they'll pour in a hot rifle-fire before making a rush. Dig for cover, Li!"
 
Grasping the idea, Li Fu took his knife to the sand and prepared two long, deep depressions at the edge of the brush.
 
Meantime, one of the boats drew in closer than the others as though to test the presence of those on the islet. Barnes sighed unavailingly for a rifle, as his pistols were of small value at such distance. He tried two shots, however, and by sheer luck dropped the boat's helmsman, so that she sheered off promptly. The boats opened a dropping rifle-fire, and Barnes retired to the position prepared. Lying beside Li Fu, he waited. He had three automatics and several spare clips. The quartermaster had two revolvers and a handful of loose cartridges.
 
Under the urge of the ground-swell, surf was now breaking in a heavy line at the bar, an outer line of breakers stretching twenty yards farther seaward. While the boats kept up their intermittent fire, bullets crashing across the island, the junk came slowly along with the morning breeze. Outside the first line of surf she dropped anchor and hauled down the brown matting sails, and the boats converged upon her. Streamers and fingers of flame were reaching across the whole eastern sky.
 
"Plenty of men aboard her," said Barnes. "They'll crowd into the boats and pull for us. Catch the first boat as she rises, Li, like we did last night. If one of them goes over in that surf, not a man will reach shore. Good gosh, look at her rise up! They're fools if they try it."
 
To the two men lying on the sandy islet, the surf promised indeed to be an excellent protection. The roaring breakers swept on and hurled up into a great wall of white and crimson spray, against the sunrise, a ten-foot wall of curling, foaming water whose impact as it came down made the islet shake and sent a booming roar echoing along the coast. The tide was coming in, and there was a strong rip along the bar.
 
Now the sun was up, in a gleaming splendor of golden glory.
 
As each glittering line of surf swept up and curled, it hid from sight the boats and all save the upper masts of the junk herself. Between the surges, the rifle-fire was maintained steadily, but Li Fu and Barnes were well protected against the ripping storm of lead that devastated the foliage above and ploughed the sand into ripples of dancing grains.
 
"They come," said Li Fu suddenly.
 
The next surf-interval showed a crowded boat leaving the junk. The craft damaged on the preceding ev............
