"Better in some ways," he said complacently. "The principle of these things is----" "I did miss it this morning," she hurried on. "In fact I had to have quite a long walk. Luckily Mr. Cromarty of Stanesland gave me a lift coming home." "Oh, indeed, miss? Stanesland gave ye a lift, did he? An interesting gentleman yon." This time she made no effort to divert Mr. Bisset's train of thought. "You think Mr. Cromarty interesting, then?" said she. "They say he's hanged a man with his ain hands," said Bisset impressively. "What!" she cried. "For good and sufficient reason, we'll hope, miss. But whatever the way of it, it makes a gentleman more interesting in a kin' of way than the usual run. And then looking at the thing on general principles, the theory of hanging is----" "Oh, but surely," she interrupted, "that isn't the only reason why Mr. Cromarty--I mean why you think he is interesting?" "There's that glass eye, too. That's very interesting, miss." She still seemed unsatisfied. "His glass eye! Oh--you mean it has a story?" "Vera possibly. He says himself it was done wi' a whisky bottle, but possibly that's making the best of it. But what interests me, miss, about yon eye is this----" He paused dramatically and she enquired in an encouraging voice: "Yes, Bisset?" "It's the principle of introducing a foreign substance so near the man's brain. What's glass? What's it consist of?" "I--I don't know," confessed Cicely weakly. "Silica! And what's silica? Practically the same as sand! Well now if ye put a handful of sand into a man's brain--or anyhow next door to it, it's bound to have some effect, bound to have some effect!" Bisset's voice fell to a very serious note, and as he was famous for the range of his reading and was generally said to know practically by heart "The People's Self-Educator in Science and Art," Cicely asked a little apprehensively: "But what effect can it possibly have?" "It might take him different ways," said the philosopher cautiously though sombrely. "But it's a good thing, anyway, Miss Farmond, that the laird of Stanesland is no likely to get married." "Isn't he?" she asked, again with that encouraging note. Bisset replied with another question, asked in an ominous voice: "Have ye seen yon castle o' his, miss?" Cicely nodded. "I called there once with Lady Cromarty." "A most interesting place, miss, illustrating the principle of thae castles very instructively." Mr. Bisset had evidently been studying architecture as well as science, and no doubt would have given Miss Farmond some valuable information on the subject. But she seemed to lack enthusiasm for it to-day. "But will the castle prevent him marrying?" she enquired with a smile. "The lady in it will," said the philosopher with a sudden descent into worldly shrewdness. "Miss Cromarty! Why?" "She's mair comfortable there than setting off on her travels again. That's a fac', miss." "But--but supposing he----" Cicely began and then paused.
