The idea of Irma's danger on the open house-top and in the full glare of the beacon acted on me like a charm--yet people will say that there is nothing at all in such a relationship as ours. Why, I would not have been half as much concerned for Agnes Anne! And as a matter of fact, I had not been so anxious down there behind the barrels and packages in the cellar, when Lalor Maitland and Galligaskins were coming at us. Besides which, I knew that Irma, being unused to fire-building, would only waste the excellent provision of kindling, and perhaps do us out of our beacon altogether. So having joined her, it was not long till we had the tarred cloth off, and, through the interstices of the iron bucket, the little blue and yellow flames began chirping and chattering. But as I pulled the basket up to the height of its iron crane, the wind of the night sent the fire off with a mighty roar. The tops of the nearer trees stood out, every leaf hard and distinct, but the main body of the woods all about Marnhoul remained dark and solid, as if you could have walked upon them without once breaking through. I stood there watching, with the chain still in my hand, though I had run the ring into the hoop on the wall. We had been very clever so far, and I was full of admiration for ourselves. But a bullet whizzing very near my head, struck the basket with a vicious "scat," doing no harm, of course, but extending to us an urgent invitation to get out of range, that was not to be disregarded. Irma was close beside me, following with her eyes the mounting crackle of the beacon, the sudden jetting of the tall pale flames that ran upward into the velvet sky of night. For from a pale and haunting grey the firmament had all of a sudden turned black and solid. Middle shades had been ruled out instantly. It was a world of ink and fire. But that sharp dash of danger cooled admiration in my heart. I caught Irma by the shoulders and, roughly enough, pulled her down beside me on the platform behind the stone ramparts. For a moment I think she was indignant, but the next thankful. For half-a-dozen balls clicked and whizzed about, passing through the square gaps that went all round the tower, as if the wall had had a couple of teeth knocked out at regular distances every here and there. Very cautiously we crawled to the stair-head, leaving our invisible enemies cracking away at the fire basket, knocking little cascades of sparks out of it, indeed, but doing no harm. For the beacon was thoroughly well alight, and the chain good and strong. As we descended the ladder I went first so as to help Irma. She was a little upset, as indeed she might well be. For it was quite evident that the number of our assailants had singularly increased, and we did not in the least know whether our signal would do us any good or not.
