Before the departure of the guests Scotty found an opportunity to confide his troubles to Isabel. He could not tell her exactly what was wrong, for that meant confessing that Callum and Grandaddy were capable of mistakes. But he vaguely hinted that he was worried over their hero. Callum was going to do something, something strange and new, but just what he could not discover. Isabel was equally perturbed. Why not ask Granny? she suggested. She would tell them. But no, Scotty explained, that was just what they must not do, for it was something that made Granny sad. But Peter Lauchie knew; Peter had told him that the shanty at the north clearing was to be fixed up for Callum to live there, after harvest; and then he laughed and would tell him no more. As usual Isabel was quick to suggest a way out of the difficulty. Why should they not go over to Peter's place some day and _make_ him tell all about it? She wanted to see Betty again, anyway, and perhaps Hughie would put up a swing for them in the barn again. This was a fine plan, and the next week they proceeded to put it into execution, and with Kirsty's permission set off early one morning for a day's visit at Long Lauchie's. Isabel was almost as well known there as Scotty himself, so he soon managed to leave her in Betty's company and go off to the fields to seek Peter. By judicious and persistent questioning he learned the confirmation of his fears. Yes, Peter and all the boys knew what the trouble was. Callum was to be married, and to an Irish girl at that, and of course all the MacDonalds were highly disgusted. Scotty listened in dismay. Callum to be married! That itself was bad enough, people were always laughed at and chaffed when they got married, and he writhed at the thought of his hero being in such an ignominious position. But to be married to an Irish girl! Surely the MacDonalds would be disgraced forever. And yet Scotty's heart forbade his taking sides against Nancy. She was Irish, certainly a deplorable fact, but still she was Nancy; and though she had not been at school for some time, the boy had not forgotten her. He sighed deeply over the complexity of human affairs. This, then, was the cause of their unhappiness at home, of Grandaddy's muttered threats and Granny's distressed looks.
