Charley was amazed and offended at what he considered the heartlessness of the physician. "You don't understand," he protested. "Mr. Morton was badly bitten, sir." Charley was still more astonished when both the ranger and the forester burst out laughing. He looked from one to the other questioningly. It did not occur to him that this was merely the doctor's way of saying that Charley had handled the situation about as well as he could have done it himself. Evidently the forester did not propose to enlighten Charley, for all he said was, "Don't let him worry you, Charley. He's just naturally lazy and a grouch. He doesn't like it because I made him hustle for once, and he's disappointed not to find Jim at the point of death. These doctors are strange animals, Charley. But with all their faults we love them still." And he slapped the physician affectionately on the shoulder. Charley looked puzzled. But concluding that silence was the best course, he said no more. All this time the doctor was continuing his labors, and Charley was amazed at the dexterous way he did things. For a moment he listened to the beating of the ranger's heart. Then, seemingly with a single motion of his knife, he slit the sleeve of the ranger's shirt. Another motion laid open the undershirt sleeve, disclosing the arm to the shoulder. The physician examined it closely. The arm was swelling fast. The physician opened his case and gave the ranger some medicine. "Now we'll get to bed as soon as possible," he said, "and rest for a few days." Assisted by a man on either side of him, the ranger started for the waiting motor-car. "Mr. Marlin," said Charley, after the party had gone a few rods, "this morning Mr. Morton brought out a little wireless set that Lew made for him, as well as my big battery. It's back where Mr. Morton was bitten. May I get it and set it up in the ranger's house? It will be a good opportunity for him to practice while he's at home. Mrs. Morton is learning to operate the wireless, too. It would mean so much to both of them and to the forest as well, if they could talk to each other by wireless." "How long will it take you to put it up, Charley?" "Not very long, sir. Perhaps an hour or two." "I don't like to leave the forest unprotected for a single minute at this season, Charley, but I guess we'll take a chance on it. Get your stuff to the road as quick as you can. I'll take Jim home and return for you." The forester hastened after the ranger's party and Charley darted off into the forest. At the fastest pace he could maintain he jogged along the fire trail. In a very little time he was back at the instruments. He took down the aerial, threw away the spreaders, uncoupled the amplifier which he needed for use himself, and replaced the little outfit in the pasteboard box. Then he hurried back to the road, where the forester was already waiting to whirl him away to the ranger's house.
