The three heads nodded vigorously, while muttered exclamations came from the negroes. Then Sam asked a question.

"Yo and Ching creep along way ober dere. Dat right," he said. "Yo wake de missie, and go back extry quick. Dat right also. What Ching do?"

Jim was ready with his answer, and flashed it at them. "Ching goes for a special reason," he said. "I happen to have had a report from the police major before I left Gatun. You will remember that a huge number of American notes were stolen. They were tied in bundles, and wrapped in waterproof paper, then the bundles were locked in boxes. Jaime and his villains broke the boxes and carried away the bundles. If those two objects out there are not the very ones we are talking of, why, call me a donkey."

Out went his finger and he pointed to the piled-up saddles and other articles which the gang had brought with them in their flight. The moon fell clearly on them all, giving every item a sharp outline; but it fell darkly on two of them, for the simple reason that they were covered in black material. Without doubt the bundles were those containing the notes filched from the Commission offices, notes which Jaime and his rascals hoped to convert into silver dollars one of these days, and so procure a fortune. Tom gasped, Sam's eyes looked as though they would fall from his head, while the Chinaman gave vent to a sniggering giggle.

"Yo am velly cleber, Mass Jim," said Tom simply. "Dem bundles de swag fo' sure, and, by lummy! me see what yo up to. Yo goin'——"

"Ching is going right now to bring 'em along with us," declared Jim in an excited whisper. "If we can take Sadie from 'em, why we'll rob the rascals of their booty also, I guess. And, gee! won't they be mad when they discover what's happened. But, boys, see here. Our job is to get away and leave them none the wiser. We want to clear off through the forest back to our people, for you may be sure that Jaime and his men will be mad when they learn how they've been fooled. So silence is important, and you'll see to it."

As if by common consent they ceased whispering to one another, and for the better part of an hour lay still in the jungle, only their heads protruding. And during all that time not one of the blanketed figures lying in the open moved so much as an inch, though there was an occasional snort or a gentle stamping from the horses.

"Guess it's time," said Jim suddenly. "Those fellows haven't moved an eyelash since we watched, and there's not a doubt but that they're properly wearied and worn out by all that they've been doin'. Tom and Sam, you know what's wanted. Give us a whistle as we come back, and then be ready to make off through the forest."

They wasted no more words. Jim went off at once on hands and knees, and, discarding the shelter of the undergrowth, made his way just within the margin of the clearing. After him came Ching, his pigtail gathered into a round coil beneath the billycock hat that he always insisted on wearing, and which, indeed, has for long been a favourite with the Chinaman. Otherwise the man was dressed in his native costume; for here, again, the wily Chinee shows his astuteness. Indeed, John Chinaman has proved to himself that his own clothing is infinitely more comfortable than European when he is located in a hot climate, and he adheres to it rigidly. Not a sound did the man make as he crept along, while Jim could not have been accused of want of caution. He carefully set aside all sticks and stones, and all fallen leaves, and never moved unless he were sure that the path was clear before him. All the time, too, he kept swinging his eyes round to the centre of the clearing. It seemed ages before he and his companion reached the northern side; but at last they were at the point where their attempt at rescue was to begin in earnest. At their feet lay a pool of water, and from it a gully some four feet deep ran right out into the open.

"Couldn't be better," whispered Jim. "We can get along on hands and knees, or wade through the water; but I hope there's little of the latter, as the splashing might be heard. Don't forget, Ching; once I have my sister, you snatch the bundles."
