The lieutenant nodded, and Nat then went below and placed himself in the hands of the assistant surgeon.

"My word, Glover, you have got your wound into a state!" the latter said after he had examined him. "What on earth have you been doing to it? It seems to have been a pretty clean break at first, and it wouldn't have bothered you above three weeks or so, but the ends have evidently been sawing away into the flesh. Why, man alive, what have you been doing?"

"I have been helping to carry a sick woman down from the hills," Nat said quietly. "If it had been level ground it would not have hurt so much, but on rough ground strewn with branches one could not avoid stumbling occasionally, and although it had been bandaged before I started the wad slipped and the thing got loose, and after that it was like walking with a red-hot needle sticking into me."

"So I should say. Well, I will put you into a berth in the sick-bay at once. Fortunately we have some ice on board and I will put some of it on the wound and try to get the inflammation down."

In a short time he returned with a basin of ice and a jugful of iced lime-juice. Nat took a long drink, and then turned so that the ice could be applied to the wound.

"You must keep yourself as still as you can. I sha'n't attempt to bandage you at present, there is really nothing to be done till we have got the inflammation down."

"I will lie quiet as long as I am awake, but I cannot answer for myself if I go off to sleep, which will not be long, for I am as tired as a dog. To-day's walk would have been nothing if I had been all right, it was the pain that wore me out."

"I don't suppose you will move. You may be sure that that rib will act like an alarm, and give you warning at once if you stir in the slightest."

Having seen Nat comfortable, the young surgeon went up on deck.

"How do you find Mr. Glover?" the first lieutenant asked. "He says that it is only a broken rib."
