“ROLL THE STONE!”
It stirred, it groaned, it grated, it moved, and with a slow grinding, as of wrathful relief, began to lean. It had waited ages to fall, and now was slow in starting. Then, as if suddenly instinct with life, it leaped hurtlingly down to alight on the steep incline, to bound more swiftly into the air, to gather momentum, to plunge into the lofty leaning crag below. The crag thundered into atoms. A wave of air—a splitting shock! Dust shrouded the sunset red of shaking rims; dust shrouded Tull as he fell on his knees with uplifted arms. Shafts and monuments and sections of wall fell majestically.
From the depths there rose a long-drawn rumbling roar. The outlet to Deception Pass closed forever.
