By then the devoted mother rabbit had vanished, doubtless filled with consternation over the dispersal of her brood, which she would have to call together in some fashion of her own. So Elmer walked on, observing many other interesting things as he proceeded, for his eyes were ever on the alert when he went into the woods and cruised on the waters.

He guessed that he must be gradually drawing up on his three chums, for occasionally he caught the sound of a halloo, as though there might be an exchange of signals between Rufus and his stakeman, who went on ahead to assist him. Lil Artha probably prowled along near by, seeing things for himself, and with not a great deal of interest in the prosaic operations of the surveyors.

Suddenly Elmer heard loud excited voices. He believed be caught the voice of Lil Artha saying, "Steady, Rufus, don't move on your life—steady, boy!"

Then came a loud report. Elmer knew that it was the discharge of the lanky scout's gun. He was already plunging forward as fast as he could go when this sound came to his startled ears. The others were close by, for he could now hear their excited voices.

A minute later, and Elmer, still on the full run, burst through a thicket, and discovered the three boys. Lil Artha had his gun half raised to his shoulder, as if doubtful whether the newcomer would prove to be a friend or an enemy; and with true scout preparedness not meaning to be taken off his guard. But on sighting Elmer, of course he lowered his weapon.

Rufus was standing there, looking as "white as a ghost," and trembling as if he had the ague. Alec grasped his small ax, and seemed quite ready to use the same. Something twisted and squirmed upon the ground, and as Elmer looked, his horrified gaze made out an enormous rattlesnake that seemed to have part of its head shot away. The chilling sound of its rattles was what Elmer had thought to be the "chill" of a buzzing locust upon some neighboring tree.

In another moment Elmer was alongside Rufus.

"Don't tell me the thing struck you, Rufus?" he ejaculated, himself pale with apprehension.

"It's all right, Elmer," said Lil Artha, soothingly. "Nobody hurt the least mite, I give you my word. But if Rufus hadn't had the good sense to stand still when I called out, I really believe the critter would have struck at him. And it was close enough to make a hit, too."

"I don't deserve any credit, fellows, indeed I don't!" said Rufus, truthfully. "I was so scared that I seemed frozen stiff. Why, I couldn't have moved hand or foot for all the money in the world. Guess that's what they mean when they say a rattler charms people."
