“Andy will get the wood,” broke in Ned, with a wink at his chums.

“Sure!” assented the small lad, and, a little later they were eating bacon and eggs, with fragrant coffee, around a merry blaze.

There was no need for haste on the trip, and the boys did not speed their auto. They felt that Professor Snodgrass, even if he were successful in finding the two-tailed lizard, would not return to his home at once. He would, most likely, remain in the mountains in search of other specimens. So the boys took their time. They planned to be two days on the road in the auto, and about as much longer in the boat, though this time could be cut down considerably if there were need for it.

They camped, on the evening of their third day’s auto trip, at the foot of a steep hill, the road having been cut through it, and high banks rising on either side. So far, aside from tire troubles, and once getting stuck in a bog, when they tried a short cut, the journey had not been eventful.

Supper was gotten at a road-side blaze, and the boys were stretched out in lazy comfort on the grass when Bob, who usually showed little desire for unnecessary exercise, scrambled to his feet.

“What’s up?” asked Jerry, looking at his fat chum.

“I thought I saw some sort of a lizard in a hole up on the face of that hill,” responded Bob. “Maybe it’s the two-tailed one the professor wants. If it isn’t it may be some kind of a rare specimen. I’ll see if I can get it for him,” and with that Bob started up the incline.

“Come back—you’ll fall,” cried Ned, for the climb was not an easy one.

“Oh, I can make it,” was the answer. “It’s some sort of a lizard sure enough, but not a two-tailed one,” and Bob pointed to where a wriggling object could be seen. His chums sat up watching him, but they were not prepared for what followed.

Bob reached for a shrub, growing on the side of the hill, intending to pull himself up by it. But, as he grasped it, the shrub pulled loose, and, an instant afterward, the stout lad toppled backward, turning completely over, and rolled to the bottom of the hill. The others could hear his head come in contact with a stone, and then poor Bob rolled into a crumpled heap, and lay motionless.
