"Plumb in the chest," he said, as he opened the shirt, and rolled Tusker over. "It aer clear that the bullet has broke through into the lung, and as fer as I can see it don't make much odds whether it's gone right through or remained inside. But we'll make sure."

By dint of the greatest care he and the man who was helping him rolled Tusker over still farther, only to discover that the ball which had struck him in the chest had wounded the lung, but had failed to emerge. It seemed, indeed, at first sight, as if there was little left for such inexperienced surgeons to do save to place the man in a comfortable position, shield him from the sun, and await his return to consciousness. But Steve was a knowing little fellow.

"I tell yer his life's extry valuable," he said, standing up beside his patient, "and we are got to move ef we want to save it. Not that he aer likely ter pull through. Reckon this aer Tusker's last call. Now, mate, lend a hand. We'll put some sort of a dressing on the wound, and then, seeing as he's still losing blood, we'll have ter make shift ter stop it. Yer see, it ain't the bleeding from the outside wound that matters. It's what's coming from the lung."

This important fact had not escaped Steve and his comrade. There was a deathly pallor about the robber chief which showed that he was desperately hurt, and that the hæmorrhage had already been severe. Then, too, the corners of his mouth were discoloured, while a few red drops hung on his chin.

"It stands ter reason," said Steve, speaking as if he were arguing the matter out with himself, "that nature aer doing her best ter help Tusker. He aer scarcely breathing, fer the simple reason thet ef he was moving his chest same as you and me, and with it his lung, why the movement of the one that's wounded would make the loss of blood even wuss. Thet bein' so, we'll take a lesson from nature. Lend a hand. Reckon we'll roll him on ter the side that's damaged. The weight of his body will hold the ribs still, and so rest the wounded lung."

Very carefully and tenderly did they set to work. An old but clean piece of linen was folded to form a dressing, and was saturated with clean, cold water. This was firmly secured to the wound in the chest by another strip of linen. Then a long pad was made with the help of a handkerchief, and some soft grass, and, having laid their pad over the dressing and its bandage, and round the chest, Steve cleverly passed a saddle girth under his patient, brought it round over the pad, and pulled it taut, till it seemed that he would arrest all movement of the ribs. Then the patient was gently rolled on to his wounded side again.

"Thet aer takin' a lesson from Mother Nature," said Steve, surveying Tusker with some satisfaction. "He is still losing blood from the lung, as you kin see from what's coming from his lips. But that 'ere girth, and layin' him on his side, will quieten the movements of his chest, and jest give him a chance. Gee! I never worked harder to save a man. I feel as anxious about him as ef he war my father, and, I kin tell yer, it means a hull heap ter young Jack thar ef Tusker pulls round."

No two nurses could have tended a patient with greater care and devotion than Steve and his fellow worker showed. They sat down in turn beside Tusker Joe, moistening his lips with water every now and again, whisking the flies away when they would have settled on his face, and holding themselves always in readiness to turn him if the position in which he was placed should appear to be harmful. But it quickly became apparent that Steve's common sense and his most valuable habit of close observation were to be rewarded. Nature, indeed, responded to the treatment, and before long it was clear that Tusker's condition, though still desperate, was slightly improved. The pallor of his face was not now so marked, while there was little if any bleeding from the lung.

"He ain't likely ter die of loss of blood now, I reckon," said Steve, surveying him critically. "It aer the shock of the wound that's going ter kill Tusker. Jest set down beside him, mate, while I have a look at Jack."

Late that evening the man who had ridden off to the settlement with a note from the sheriff returned, and with him a young surgeon. By then Jack had awakened, and, but for a slight headache and a good deal of stiffness, was himself again. Therefore there was no need for him to have attention. The surgeon at once went to Tusker's side, and for half an hour devoted all his skill to him.
