"Oh yes, grandmother dear," said Molly serenely. "It means—it means—oh I don't quite know, but I'm sure I do know."

"Think of it as meaning the not saying or doing to another person whatever in that other's place you would not like said or done to you—that is one meaning of tact anyway, and a very good one. Will you try to remember it, Molly?"

Molly opened her eyes.

"Yes, grandmother dear, I will try. But I think all that will be rather hard to remember, because you see people don't feel the same. My head isn't twisty-turny enough to understand things like that, quickly. I like better to go bump at them, quite straight."

"Without, in nine cases out of ten, the faintest idea what you are going to go bump straight at," said aunty, laughing. "Oh, Molly, you are irresistible!"

The laughing at her had laughed back Ralph's good humour anyway, and now he returned to the charge.

"Twisty-turny is like a corkscrew, grandmother," he said slyly, "and once there was an old house with a corkscrew stair——"

"Yes," said grandmother, "and in that old house there once lived an old lady, who, strange to say, was not always old. She was not very old at the time of the 'adventure.' You remember, children, my telling you that during her husband's life, my grandmother and he used to spend part of the winter in the old house where she afterwards ended her days. My grandfather used to drive backwards and forwards to his farms, of which he had several in the neighbourhood, and the town was a sort of central place for the season of bad weather and short days. Sometimes he used to be kept rather late, for besides his own affairs, he had, like his son, my father, a good deal of magistrate's business to attend to. But however late he was detained my grandmother always sat up for him, generally in a little sitting-room she had on the storey above the long drawing-room I have described to you, almost, that is to say, at the top of the house, from attic to basement of which ran the lung 'twisty-turny, corkscrew staircase.' One evening, about Christmas time it was, I think, my grandfather was very late of coming home. My grandmother was not uneasy, for he had told her he would be late, and she had mentioned it to the servants, and told them they need not sit up. So there she was, late at night, alone, sewing most likely—ah girls, I wish I could show you some of her sewing—in her little parlour. She was not the least nervous, yet it was a little 'eerie' perhaps, sitting up there alone so late, listening for her husband's whistle—he always whistled when he was late, so that she might be sure it was he, when she went down to open the door at his knock—and more than once she looked at the clock and wished he would come. Suddenly a step outside the room, coming up the stair, made her start. She had hardly time to wonder confusedly if it could be my grandfather, knowing all the time it could not be he—the doors were all supposed to be locked and barred, and could only be opened from the inside—when the door was flung open and some one looked in. Not my grandfather certainly; the man who stood in the doorway was dressed in some sort of rough workman's clothes, and his face was black and grimy. That was all she had time to catch sight of, for, not expecting to see her there, the intruder, startled, turned sharply round and made for the stair. Up jumped my little grandmother; she took it all in in an instant, and saw that her only chance was to take advantage of his momentary surprise and start at seeing her. Up she jumped and rushed bravely after him, making all the clatter she could. Downstairs he flew, imagining very probably in his fright that two or three people instead of one little woman were at his heels, and downstairs, round and round the corkscrew staircase, she flew after him. Never afterwards, she has often since told me, did she quite lose the association of that wild flight, never could she go downstairs in that house without the feeling of the man before her, and seeming to hear the rattle-rattle of a leathern apron he was wearing, which clattered against the banisters as he ran. But she kept her head to the end of the chase; she followed him—all in the dark, remember—down to the bottom of the staircase, and, guided by the clatter of his apron, through a back kitchen in the basement which opened into a yard—there she stopped—she heard him clatter through this cellar, banging the door—which had been left open, and through which he had evidently made his way into the house—after him, as if to prevent her following him farther. Poor thing, she certainly had no wish to do so; she felt her way to the door and felt for the key to lock it securely. But alas, when she pushed the door closely to, preparatory to locking it, it resisted her. Some one or something seemed to push against her from the outside. Then for the first time her courage gave way, and thinking that the man had returned, with others perhaps, she grew sick and faint with fright. She sank down helplessly on the floor for a moment or two. But all seemed quiet; her courage and common sense returned; she got up and felt all about the door carefully, to try to discover the obstacle. To her delight she found that some loose sand or earth driven into a little heap on the floor was what prevented the door shutting. She smoothed it away with her hand, closed the door and locked it firmly, and then, faint and trembling, but safe, made her way back to the little room where her light was burning. You can fancy how glad she was, a very few moments afterwards, to hear my grandfather's cheerful whistle outside."

"But," interrupted Molly, her eyes looking bigger and rounder than usual, "but suppose the man had been waiting outside to catch him—your grandfather—grandmother, when he came in?"

"But the man wasn't doing anything of the sort, my dear Molly. He had gone off in a fright, and when my grandmother thought it over coolly, she felt convinced that he was not a regular burglar, and so it turned out. He was a man who worked at a smithy near by, and this was his first attempt at burglary. He had heard that my grandfather was to be out late, through one of the servants, whom he had persuaded not to lock the door, on the pretense that he might be passing and would look in to say good-night. It all came out afterwards."
