'Heriot tells me that you are not looking well—that you want a change, Mildred,' her brother said to her one day, and, to his surprise, she looked annoyed, and answered more hastily than her wont—

'There is nothing the matter with me, at least nothing of consequence. I am not one of those who are always fancying themselves ill.'

'But you are thinner. Yes, I am sure he is right; you are thinner, Mildred.'

'What nonsense, Arnold; he has put that in your head.

By and by I shall be glad of a little change, I daresay. When Mr. Fabian leaves Roy, I mean to take his place.'

'A good idea,' responded Mr. Lambert, warmly; 'it will be a treat for Rex, and will do you good at the same time. I was thinking of running up myself after Christmas. One sees so little of the boy, and his letters are so short and unsatisfactory; he seems a little dull, I fancy.'

'Mr. Fabian will cheer him up,' replied Mildred, evasively. She was thankful when her brother went back to his study. She felt more than usually oppressed and languid that day, though she would not own it to herself; her work wearied her, and the least effort to talk jarred the edge of her nerves.

'How dreadful it is to feel so irritable and cross, as I have done lately,' she thought. 'Perhaps after all he is right, and I am not so strong as usual; but I cannot have them all fancying me ill. The bare idea is intolerable. If I am going to be ill, I hope I may know it, that I may get away somewhere, where his kindness will not kill me.'

She shivered here, partly from the thought, and partly from the opening of the door. A keen wind whistled through the passage, a rush of cold air followed Polly as she entered. Dr. Heriot was with her.

His cordial greeting was as hearty as ever.
