A habit of standing first on one leg, and then on the other, had earned him the nickname of "Heron," and it was thus disrespectfully, but affectionately, that his sister usually addressed him. A man of unbounded possibilities, but indifferent achievements, only a total lack of ambition and enterprise prevented his rolling the ball still at his feet, but, as it was, he had never improved on the fame that came to him when quite a young man.

"The first man in England on his subject," was what his colleagues said of him, "but doesn't seem to push his opportunities; nice fellow, too!" while Frank Lawless himself, after a merciless tirade from Gay, would remark:

"My dear, I have used my brains to the best of my ability. My name is not unknown, and there are some eminent men who seek my opinion still, and value it. I do not wish to become a public character—to be obscure is to be happy—why not leave me to the work I love? I do not remember an instance in which I have interfered with you, though I must confess that some of your exploits—notably hunting, a practice I detest—have caused me some anxiety. Live and let live, my child," and waving a hand that clasped a test-tube, the Professor would flee to the safety of the laboratory, to which haven Gay never intruded, the smells were too awful, she said.

Since the death of their parents, Gay had taken up her abode with her brother in London. The girl was really very fond of him, and though they had few tastes in common, she thought it her duty, as well as her pleasure, to look after him, and, as she expressed it, "dress and wash him up generally."

The arrangement answered admirably. Gay was free as air to go where she liked, and do what she pleased, while the Professor followed his own pursuits, and took a secret delight in being well taken care of, without having to suffer the infliction of a wife.

In fact, so secure did he feel under existing circumstances, that the prospect of their interruption sometimes occurred to him with an unpleasant shock, and the possibility of his sister marrying appalled him. He consoled himself, however, with the reflection that she seemed in no hurry, and no one could accuse him of attempting to cross bridges before he met them; his character was rather the reverse, in fact, his impulse being to walk round any obstacle that presented itself, or if this proved impossible, to confront it sideways, and wait till either it removed itself, or someone—usually Gay—came to the rescue.

This disinclination to show a bold front to however trivial a difficulty, was the twin trait to his lack of ambition, and his attitude was pathetic when a worldly problem faced him, for he could no more reprimand or dismiss a worthless servant, than he could in cold blood destroy one of his cherished specimens.

"She does her best, poor thing!" It was thus he one day mildly excused an obstreperous and drunken cook, who had "held up" the whole household. "It must be very trying to stand over a fire all day, you know, and, er—she's only a little excited, is she?"

"She's drunk," Gay said emphatically. "She went for Sanders with the rolling-pin just now. I want you to see her, and tell her that if she's not out of the house, bag and baggage, in an hour, you'll send for the police."

This was, of course, a joke, but Gay spoke so seriously, and appeared so much in earnest, that the Professor felt in immediate danger of participating in a scene, and looked all the fright he felt.
