“Capital fellow, Linton,” said the doctor. “Nothing like fruit in moderation to keep men in health. But isn’t it risky to have these fellows on the isle?”

“I have thought of that,” said Mr Linton; “but by being too exclusive we shall defeat our own ends. We must receive the principal part of the Malays in a friendly way, and it is only by a more open policy that this can be done. If we admit any wolves amongst the sheep they must meet with the wolves’ fate. So far I think I have done well.”

“Well, yes, perhaps you are right,” said the doctor. But both gentlemen would have altered their opinions exceedingly if they had seen a long low boat, painted of a dark grey, and manned by six men, float gently down stream that night, and, unseen by the sentries, stop beside the sampan of Abdullah and his Malay companion.

Here there was a short consultation, Abdullah crawling over the gunwale into the long low boat, where he lay down, side by side with the man who steered.

Their conversation was long, and the others in the boat lay down while it was going on, so that had the boat been seen by an unusually watchful sentry it would have appeared to be empty, and moored to a bamboo stake thrust into the mud.

But the dark silent boat was not seen by the nearest sentry, either when it floated down, or when it was cautiously turned and paddled up stream once more, till, out of hearing, the oars went down with a noisy splash, and the long narrow vessel literally dashed through the river.

The reason it was not seen was simple enough.

Private Sim was on duty that night, and he had been once more fast asleep.
