She nodded good-bye to David Bain and passed on, hastening more quickly than usual past the farm-house of Darrach, though there lived one of her best and most faithful friends in the whole glen--one Elspeth Mackay married to Donald Maclure, the big crofter who was respected in the glen, from end to end of it, as a man of his word. But Elspeth’s tongue was long and her eyes were very keen, and Isla was not ready for them yet. Therefore she hastened past the gate of Darrach, not even smiling as the rich, fine smell of Elspeth’s baking was borne out through the open door. Down the hill a little way she came to the old brig that crossed the Darrach burn; and there she paused, for there was no one in sight and the slope hid her from view of Elspeth’s windows. She could never afterwards recall that half-hour by the Darrach Brig without an inward shudder. Thus did Malcolm Mackinnon, the ne’er-do-weel, write airily and lightly, telling the miserable story that well nigh broke his sister’s heart:-- "DEAR ISLA,--Last time you wrote me you hoped I would have better news to send next time. I’m sorry I can’t comply. I seem to have the devil’s own luck here in this beastly country. In fact, I may as well say at once that it’s all up with me and that I’m coming home. "I’ve never been very happy in the Thirty-fifth nor got on well with old Martindale. He’s a beast, if ever there was one, a regular martinet, and unless you practise the whole art of sucking up to him you may as well give up the ghost, as far as any chance of promotion or even of fair play is concerned. Of course, no Mackinnon can suck up to anybody--we’ve got too much beastly pride. Anyway, I haven’t been able to soft-sawder Martindale enough, and I have been in his black books ever since I joined. But it’s got a lot worse in the last nine months. "When I wrote the governor last year, asking him to use his influence to get me shifted, I was quite in earnest, and if he’d done it all this row might have been prevented. We’ve been up country a goodish bit since I wrote last, and there again I didn’t get fair play or a bit of a chance. We’ve had several brushes with a hostile tribe, but the other chaps got their innings every time and nothing but the dirty work was left to me. We had such a lot of beastly, unnecessary fag on our marches that most of the chaps were on the verge of mutiny; but I was the only one with the courage to speak up. Whatever garbled version of the story may get home, you may take it from me, old girl, that is the bottom truth of it. Anyhow, I’ve got to send in my papers--that’s the long and the short of it. All the chaps, except the few that suck up to Martindale, think I’ve been treated most beastly badly, and unjustly besides. But of course nobody listens to a poor subaltern’s defence or excuse.
