Yet this is but half the picture; our Silverado platform has another side to it. Though there was no soil, and scarce a blade of grass, yet out of these tumbled gravel-heaps and broken boulders, a flower garden bloomed as at home in a conservatory. Calcanthus crept, like a hardy weed, all over our rough parlour, choking the railway, and pushing forth its rusty, aromatic cones from between two blocks of shattered mineral. Azaleas made a big snow-bed just above the well. The shoulder of the hill waved white with Mediterranean heath. In the crannies of the ledge and about the spurs of the tall pine, a red flowering stone-plant hung in clusters. Even the low, thorny chaparral was thick with pea-like blossom. Close at the foot of our path nutmegs prospered, delightful to the sight and smell. At sunrise, and again late at night, the scent of the sweet bay trees filled the canyon, and the down-blowing night wind must have borne it hundreds of feet into the outer air.
