“No,” said Sam, “only an amateur; nevertheless I know what I’m about. You see, I think that every man in the world, whatever his station or profession, should be at least slightly acquainted with every subject under the sun in connection with which he may be called on to act. In other words, he should know at least a little about surgery, and physic, and law, and carpentering, blacksmithing, building, cooking, riding, swimming, and—hallo! why, two of your ribs are broken, my man!”

“Sorry to hear it, sir, but not surprised, for I feels as if two or three o’ my spines was broken also, and five or six o’ my lungs bu’sted. You won’t be able to mend ’em, I fear.”

“Oh, yes, I shall,” said Sam cheerily.

“Ah! that’s well. I’d thowt that p’r’aps you wouldn’t have the tools ’andy in these parts for splicin’ of ’em.”

“Fortunately no tools are required,” returned Sam. “I’ll soon put you right, but you’ll have to lie still for some time. Here, Robin, go into the store-cave and fetch me a few yards of that white cotton, you remember, near the door. And, I say, mind you keep well clear of the powder.”

When the cotton was brought, Sam tore it up into long strips, which he wound somewhat tightly round the sailor’s huge chest.

“You see,” he observed, as he applied the bandages, “broken ribs are not necessarily displaced, but the action of breathing separates the ends of them continually, so that they can’t get a chance of re-uniting. All we have to do, therefore, is to prevent your taking a full breath, and this is accomplished by tying you up tight—so. Now, you can’t breathe fully even if you would, and I’d recommend you not to try. By the way—what’s your name?”

“Johnson, sir,—John Johnson.”

“Well, Johnson, I’ll give you something to eat and drink now, after which you’ll have another sleep. To-morrow we’ll have a chat on things in general.”

“I say,” asked Robin that night, as he and Sam stood star-gazing together beside a small fire which had been kindled outside the cavern-mouth for cooking purposes, “is it true that you have studied all the subjects you mentioned to Johnson this morning?”
