don't suppose she wants too many of us."

"We have an invitation to a ball, doctor," Lieutenant Gulston said after leaving the captain, to their ship's doctor, "for the 20th, at a Mrs. Mervyn's. The captain says we had better not go more than three. Personally I rather want to go. So Hilton of course must remain on board, and Lucas can go. I know you like these things, although you are not a dancing man. As a rule it goes sorely against my conscience taking such a useless person as one of our representatives; but upon the present occasion it does not matter, as there is a son of the house in the Borderers; and, of course, they will put in an appearance in strength."

"A man can make himself very useful at a ball, even if he doesn't dance, Gulston," the doctor said. "Young fellows always think chits of girls are the only section of the female sex who should be thought of. Who is going to look after their mothers, if there are only boys present? The conversation of a sensible man like myself is quite as great a treat to the chaperones as is the pleasure of hopping about the room with you to the girls. The conceit and selfishness of you lads surprise me more and more, there are literally no bounds to them. How far is this place off?"

"It's about twenty miles by road, or about fifteen by train, and eight or nine to drive afterwards. I happen to know about the place, as it's close to the village where I was fishing a fortnight ago."

"Then I think the chaperones will have to do without me, Gulston. I am fond of studying human nature, but if that involves staying up all night and coming back in the morning, the special section of human nature there presented must go unstudied."

"I have been thinking that one can manage without that, doctor. There is a very snug little inn where I was stopping in the village, less than a mile from the house. I propose that we go over in the afternoon, dine at the inn, and dress there. Then we can get a trap to take us up to the Mervyns', and can either walk or drive down again after it is over, or come back by train with the others, according to the hour and how we feel when the ball is over."

"Well, that alters the case, lad, and under those conditions I will be one of the party."

CHAPTER II.

MARGARET CARNE.

Ronald Mervyn was, perhaps, the most popular man in his regiment. They were proud of him as one of the most daring steeplechase riders in the service, and as a man who had greatly distinguished himself by a deed of desperate valour in India. He was far and away the best cricketer in the corps; he could sing a capital song, and was an excellent musician and the most pleasant of companions. He was always ready to do his friends a service, and many a newly-joined subaltern who got into a scrape had been helped out by Ronald Mervyn's purse. And yet at times, as even those who most liked and admired him could not but admit, Ronald Mervyn was a queer fellow. His fits were few and far between, but when they occurred he was altogether unlike himself. While they lasted, he would scarce exchange a word with a soul, but shut himself in his room, or, as soon as parade was over, mounted his horse and rode off, not to return probably until late at night.

Mervyn's moods were the subject of many a quiet joke among the young officers of the regiment. Some declared that he must have committed a murder somewhere, and was occasionally troubled in his conscience; while some insisted that Mervyn's strange behaviour was only assumed in order that he might be the more appreciated at other times. Among the two or three officers of the regiment who came from that part of the country, and knew something of the family history of the Mervyns, it was whispered that he had inherited some slight share of the curse of the Carnes. Not that he was mad in the slightest degree—no one would think of saying that of Ronald Mervyn—but he had certainly queer moods. Perhaps the knowledge that there was a taint in his blood affected him, and in course of time he began to brood over it.

When this mood was on him, soon after joining the regiment, he himself had spoken to the doctor about it.

"Do you know, doctor, I am a horrible sufferer from liver complaint?"

"You don't look it, Mervyn," the surgeon replied; "your skin is clear, and your eye is bright. You are always taking exercise, your muscles are as hard as nails. I cannot believe that there is much the matter with you."

"I assure you, doctor, that at times for two or three days I am fit for nothing. I get into such a state that I am not fit to exchange a word with a human being, and could quarrel with my best friend if he spoke to me. I have tried all sorts of medicines, but nothing seems to cure me. I suppose it's liver; I don't know what else it can be. I have spoken about it to the Major, and asked him if at any time he sees me look grumpy, to say a word to the mess, and ask them to leave me to myself; but I do wish you could give me something."

The doctor had recommended courses of various foreign waters, and had given him instructions to bathe his head when he felt it coming on; but nothing had availed. Once a year, or sometimes oftener, Ronald retired for two or three days, and then emerged as well and cheerful as before.

Once, when the attack had been particularly severe, he had again consulted the doctor, this time telling him the history of his family on his mother's side, and asking him frankly whether he thought these periodical attacks had any connection with the family taint. The doctor, who had already heard the story in confidence from one of the two men who knew it, replied:

"Well, Mervyn, I suppose that there's some sort of distant connection between the two things, but I do not think you are likely to be seriously affected. I think you can set your mind at ease on that score. A man of so vigorous a frame as you are, and leading so active and healthy a life, is certainly not a likely subject for insanity. You should dismiss the matter altogether from your mind, old fellow. Many men with a more than usual amount of animal spirits suffer at times from fits of depression. In your case, perhaps due, to some extent, to your family history, these fits of depression are more severe than usual. Probably the very circumstance that you know this history has something to do with it, for when the depression—which is, as I have said, not uncommon in the case of men with high spirits, and is, in fact, a sort of reaction—comes over you, no doubt the thought of the taint in the blood occurs to you, preys upon your mind, and deeply intensifies your depression."

"That is so, doctor. When I am in that state my one thought is that I am going mad, and I sometimes feel then as if it would be best to blow out my brains and have done with it."

"Don't let such a fancy enter your head, Mervyn," the doctor said, earnestly. "I can assure you that I think you have no chance whatever of becoming insane. The fits of depression are of course troublesome and annoying, but they are few and far apart, and at all other times you are perfectly well and healthy. You should, therefore, regard it as I do—as a sort of reaction, very common among men of your sanguine temperament, and due in a very slight degree to the malady formerly existent in your family. I have watched you closely since you came to the regiment, and, believe me, that I do not say it solely to reassure you when I affirm that it is my full belief and conviction that you are as sane as other men, and it is likely that as you get on in life these fits of depression will altogether disappear. You see both your mother and uncle were perfectly free from any suspicion of a taint, and it is more than probable that it has altogether died out. At any rate the chances are slight indeed of its reappearing in your case."

"Thank you, doctor; you can imagine what a relief your words are to me. I don't worry about it at other times, and indeed
