“There is nothing to mind,” the captain said as he helped them down to the boat. “The Malays will no doubt pass us by. I expect that by morning they will be many miles away. Still it is a bit of a scare.”

Neither Mark nor Mrs Strong made any reply; but the stowaway, who was pretty well recovered from his exhaustion, whispered to Billy Widgeon that he hoped it might be so; and then silence fell upon the boat as they rowed slowly back toward the crater, where it was the captain’s intention to get the ladies on board the little vessel. But this proved to be no easy task in the darkness, and at last it was decided to make the sands their couch for the night, and then see what the day would bring forth.

Mark was so utterly wearied out, that after partaking of his share of the refreshments left, he lay for a few minutes gazing at the reflections of the flickering light from the mountain cast upon the sea, and then dropped fast asleep, but only to be awakened by a sound like thunder reverberating overhead. It died away and all was silence and darkness again; and then all seemed to be nothingness as he fell into a dreamless sleep, hardly even conscious of whether a watch was kept.

Mark was awakened by a hand being laid upon his mouth and a voice whispering in his ear the one word, “Hush!”

It was dark still and the stars were shining, while every now and then there was a flash as of lightning followed by an intense blackness in which the pained eyes seemed to repeat the form of the flash.

“What is the matter?” whispered Mark.

“Don’t speak, but get up and follow. The others have gone on. Above all things keep that dog from barking.”

“The Malays have come!” thought Mark on the instant, and as he rose he looked round; but there was nothing to be seen, and he was wondering where the danger lay as he followed his father over the black sand towards where the boat was always dragged over the low point beyond the rocks, where he had just time to catch Bruff’s head and press his hands round his pointed muzzle; for from about a couple of hundred yards away there came the low muttering of voices, followed by a yawn, and by Bruff with a low muttering growl.
