Nevertheless with these inferior barks they held the fever in check. But the pain was obstinate, and cost Helen many a sigh; for, if she came softly, she could often hear him moan; and, the moment he heard her foot, he set to and whistled, for a blind; with what success may be imagined. She would have bought those pains, or a portion of them; ay, and paid a heavy price for them.
But pain, like everything, intermits, and in those blessed intervals his mind was more active than ever, and ran a great deal upon what he called the Problem.
But she, who had set it him, gave him little encouragement now to puzzle over it.
The following may serve as a specimen of their conversation on that head.
"The air of this island," said he, "gives one a sort of vague sense of mental power. It leads to no result in my case. Still, it is an agreeable sensation to have it floating across my mind that some day I shall solve the Great Problem. Ah! if I was only an inventor!"
"And so you are."
"No, no," said Hazel, disclaiming as earnestly as some people claim; "I do things that look like acts of invention, but they are acts of memory. I could show you plates and engravings of all the things I have seemed to invent. A man who studies books instead of skimming them can cut a dash in a desert island, until the fatal word goes forth—invent; and then you find him out."
"I am sure I wish I had never said the fatal word. You will never get well if you puzzle your brain over impossibilities."
"Impossibilities! But is not that begging the question? The measure of impossibilities is lost in the present age. I propose a test. Let us go back a century, and suppose that three problems were laid before the men of that day, and they were asked to decide which is the most impossible: 1st, to diffuse intelligence from a fixed island over a hundred leagues of water; 2d, to make the sun take in thirty seconds likenesses more exact than any portrait-painter ever took—likenesses that can be sold for a shilling at fifty per cent profit; 3d, for New York and London to exchange words by wire so much faster than the earth can turn, that London shall tell New York at ten on Monday morning what was the price of consols at two o'clock Monday afternoon."
"That is a story," said Helen, with a look of angelic reproach.
