"No, I don't think so," the doctor said, gravely. "No, I should say certainly not; but you know in these cases where it is in the blood it sometimes lies dormant for a generation and then breaks out again. I asked somebody casually last night about their father, and he said that he was a capital fellow and most popular in the country; so if it is in the blood it passed over him, and is showing itself again in the son. It may pass over the daughter and reappear in her children. You never know, you see. Do you mind telling me what you know about the family?" "Not now; not at present. I will at some other time. You have given me a shock, and I must think it over." The doctor nodded, and commenced to talk about other matters. A minute or two later the lieutenant made some excuse, and turned into the cabin. Dr. Mackenzie shook his head. "The lad is hard hit," he said, "and I am sorry for him. I hope my warning comes in time; it will do if he isn't a fool, but all young men are fools where women are concerned. I will say for him that he has more sense than most, but I would give a good deal if this had not happened." Lieutenant Gulston was, indeed, hard hit; he had been much struck with the momentary glance he had obtained of Margaret Carne as he stood on the steps of the "Carne Arms," and the effect had been greatly heightened on the previous day. Lieutenant Gulston had, since the days when he was a middy, indulged in many a flirtation, but he had never before felt serious. He had often laughed at the impressibility of some of his comrades, and had scoffed at the idea of love at first sight, but now that he began to think matters seriously over, the pain the doctor's remarks had given him opened his eyes to the fact that it was a good deal more than a passing fancy. Thinking it over in every light, he acknowledged the prudent course would be to send some excuse to her brother, with an expression of regret that he found that a matter of duty would prevent his coming over, as he had promised, for the shooting. Then he told himself that after all the doctor might be mistaken, and that it would be only right that he should judge for himself. If there was anything in it, of course he should go no more to The Hold, and no harm would be done. Margaret was certainly very charming; she was more than charming, she was the most lovable woman he had ever met. Still, of course, if there was any chance of her inheriting this dreadful thing, he would see her no more. After all, no more harm could be done in a couple of days than had been done already, and he was not such a fool but that he could draw back in time. And so after changing his mind half-a-dozen times, he resolved to go over for the shooting.
