Then, as the midday sun withdraws from the gulf the shadow of the mountains, the clouds begin to roll out of the lower valleys. They swathe in sombre tatters the naked crags of precipices above the wooded slopes, hide the peaks, smoke in stormy trails across the snows of Higuerota.
The wasting edge of the cloud-bank always strives for, but seldom wins, the middle of the gulf. The sun—as the sailors say—is eating it up. Unless perchance a sombre thunder-head breaks away from the main body to career all over the gulf till it escapes into the offing beyond Azuera, where it bursts suddenly into flame and crashes like a sinster pirate-ship of the air, hove-to above the horizon, engaging the sea.
