That faint light was only visible for a few moments, then all was dark again, but it was a transparent darkness, gradually growing clearer. Then a tree seemed to start up on the scene, and a clump of bushes nearer the fire. Soon after he could make out a great patch of feathery green, and this had hardly grown clear enough for him to be certain what it was, when something misty and undefined appeared to be moving along the bank close to the tree to which the boat was tethered. The next moment it melted away into the soft darkness.

“Fancy!” said Rob to himself. But directly after he knew it was not fancy, for he could hear a peculiar scratching, rending sound, which put him in mind of a cat tearing with its claws at the leg of a table.

And now as if by magic there was a soft warm glow diffused around, and, to his surprise and delight, he saw again the object he had before noticed, but no longer undefined. It was grey, and looked transparent, but it was a warm-grey, and grew moment by moment less transparent, gradually assuming the shape of his friend of the previous day, alive and to all appearances uninjured, as, with its soft, elastic, cat-like step and undulating body and tail, it walked slowly down to the edge of the bank, and stood staring at Rob as if waiting for him to speak.

For a few moments the lad was silent and motionless, as he strove hard to detect signs of injury upon the soft, coat of the puma, but nothing was visible, and the animal remained as motionless as he, save that the long tail writhed and curled about as a snake might if gently held by its head.

The next minute Rob had decided what to do.

Creeping silently astern, he unfastened and paid out a good deal of the line which held the boat to the grapnel. Then refastening it, he went silently forward, and began to haul upon the other line, which was secured to the tree ashore, thus bringing the boat’s head close up to the bank and within half a dozen yards of the puma, which stood watching him till the boat touched the bank, when, without hesitation or fear of consequences, Rob stepped ashore.

“Fine chance for him if he does mean to eat me!” thought Rob, with a laugh. But the next moment he did feel startled, for the animal suddenly crouched, gathered its hind legs beneath it, and he could see them working as the agile creature prepared to spring.

Rob’s heart beat heavily, and a cry rose to his lips, but was not uttered, for he felt paralysed, and he would have proved to be an unresisting victim had the puma’s intentions been inimical. But the lad soon knew that they were friendly, for the great bound the creature gave landed it at his feet, where it immediately rolled over on to its side, then turned upon its back, and with touches soft as those of a kitten pulled at the boy’s legs and feet, looking playfully up at him the while.

“Why, you are a tame one,” said Rob, with a sigh of relief. “There’s no danger in you whatever,” and sinking on one knee, he patted and rubbed the great soft head which was gently moved about in his hand.

So satisfactory was this to the puma that it rolled itself about on the ground, pressed its head against Rob’s knee, and finally turned over once more, couched, laid its head against him, and gazed up in his eyes as he placed his hand upon the soft browny-grey head.
