"That was a hunky-dory supper, all right," Steve admitted, as he lay lazily back on his blanket, and commenced to pick his teeth after the manner of one who has dined well, and is perfectly at peace with the whole world.

"Best I've had since the last time we ate grub together," Bandy-legs added, as his quota of praise, although he had been one of the cooks.

"And that was up in the Great North Woods, when we spent that joyful time with Trapper Jim, wasn't it!" Max suggested.

"I'd sure like mighty well to repeat that trip some of these fine days," Steve told them, "but I reckon we never will, because there are so many other temptations all around us. And seems like we might squeeze all the fun we can manage out of this little vacation. Here we are, away off from everywhere, and if we want we can just think we're camping in the heart of Africa, with wild beasts all around us and savage Hottentots or Zulu warriors waiting to take us by surprise."

Steve liked to indulge in these little flights of fancy once in a while. His imagination sometimes ran away with him; but he seemed to get considerable of enjoyment out of the idea.

Hardly had he ceased speaking on the present occasion than each one of the four boys sat upright, and seemed to be straining his hearing to the utmost, as though some sound had come to them then and there that caused surprise, even consternation.

"S-s-say, w-w-whatever was that n-n-noise like thunder?" asked Toby, blankly.

Steve looked puzzled.

"That's what's got my goat, Toby," he remarked in a perplexed tone of voice; it might be one thing or another, but it sure wasn't thunder. "As for me, now, I'm racking my poor brains to guess whether it could only have been a farmer's bull bellowing away off there; or we sat here and actually, listened to a savage African lion at large!"

His words appalled every one, and it was well that supper had been eaten, else their appetites might have suffered a decided slump.
