With a shudder running through me I rose to my elbow, at the same moment seizing my gun, when a single intent glance convinced me that I was right, for certainly some creature was watching the doctor, and probably crouching before making a deadly bound.

I cocked the piece softly, holding the trigger the while, so that there should be no sharp click, and in another moment I should have fired, after careful aim, between the two bright glaring eyes, when the doctor made a movement, and the animal darted aside and went bounding off, just giving me a glimpse of its form, which was that of a small deer.

I saw the doctor shade his eyes and stand watching the flying creature. Then stooping down he picked up a few branches that had been gathered ready, and made the fire blaze more brightly.

As the glow increased I saw something which there was no mistaking for a harmless deer, for not ten yards away there was a large cat-like creature crouching close to the ground, while, to make assurance doubly sure, there came from between its bared and glistening white teeth a low angry snarl.

I took aim, and tried to get a good sight at its head, but hesitated to draw trigger, for the glow from the fire made appearances deceptive, the body of the cat-like beast seeming to waver up and down; and directly after the creature moved, and its head was covered by a low bush.

But the doctor and his companion had both seen the animal, which uttered a menacing roar as the former stepped forward, snatched a piece of burning wood from the fire, and hurled it towards the beast, his example being followed by the New Guinea man.

The result was a furious roar, and the great cat bounded away towards the forest.

This brought Gyp to his feet with a fierce volley of barking, and he would have been off in pursuit but for his master, who woke up and ran out exclaiming:

“Dingoes after the sheep! dingoes after the sheep! Here, Gyp, boy! here, Gyp—here—eh! I say, is anything the matter?”

“No, no; all right!” cried the doctor.
