These, then, are the legendary inhabitants of Azuera guarding its forbidden wealth; and the shadow on the sky on one side, with the round patch of blue haze blurring the bright skirt of the horizon on the other, mark the two outermost points of the bend which bears the name of Golfo Placido, because never a strong wind had been known to blow upon its waters.
On crossing the imaginary line drawn from Punta Mala to Azuera the ships from Europe bound to Sulaco lose at once the strong breezes of the ocean.
They become the prey of capricious airs that play with them for thirty hours at a stretch sometimes. Before them the head of the calm gulf is filled on most days of the year by a great body of motionless and opaque clouds. On the rare clear mornings another shadow is cast upon the sweep of the gulf. The dawn breaks high behind the towering and serrated wall of the Cordillera, a clear-cut vision of dark peaks rearing their steep slopes on a lofty pedestal of forest rising from the very edge of the shore.
Amongst them the white head of Higuerota rises majestically upon the blue.
Bare clusters of enormous rocks sprinkle with tiny black dots the smooth dome of snow.
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 Cordillera is gone from you as if it had dissolved itself into great piles of grey and black vapours that travel out slowly to seaward and vanish into thin air all along the front before the blazing heat of the day. 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 thunderhead 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 sinister pirate-ship of the air, hove-to above the horizon, engaging the sea.
At night the body of clouds advancing higher up the sky smothers the whole quiet gulf below with an impenetrable darkness, in which the sound of the falling showers can be heard beginning and ceasing abruptly -- now here, now there. Indeed, these cloudy nights are proverbial with the seamen along the whole west coast of a great continent. Sky, land, and sea disappear together out of the world when the Placido -- as the saying is -- goes to sleep under its black poncho. The few stars left below the seaward frown of the vault shine feebly as into the mouth of a black cavern. In its vastness your ship floats unseen under your feet, her sails flutter invisible above your head. The eye of God Himself -- they add with grim profanity -- could not find out what work a man's hand is doing in there; and you would be free to call the devil to your aid with impunity if even his malice were not defeated by such a blind darkness.
The shores on the gulf are steep-to all round; three uninhabited islets basking in the sunshine just outside the cloud veil, and opposite the entrance to the harbour of Sulaco, bear the name of `The Isabels'.
There is the Great Isabel; the Little Isabel, which is round; and Hermosa, which is the smallest.
That last is no more than a foot high, and about seven paces across, a mere flat top of a grey rock which smokes like a hot cinder after a shower, and where no man would care to venture a naked sole before sunset. On the Little Isabel an old ragged palm with a thick bulging trunk rough with spines, a very witch amongst palm trees, rustles a dismal bunch of dead leaves above the coarse sand. The Great Isabel has a spring of fresh water issuing from the overgrown side of a ravine. Resembling an emerald green wedge of land a mile long, and laid flat upon the sea, it bears two forest trees standing close together, with a wide spread of shade at the foot of their smooth trunks. A ravine extending the whole length of the island is full of bushes; and presenting a deep tangled cleft on the high side spreads itself out on the other into a shallow depression abutting on a small strip of sandy shore.
From that low end of the Great Isabel the eye plunges through an opening two miles away, as abrupt as if chopped with an axe out of the regular sweep of the coast, right into the harbour of Sulaco. It is an oblong, lake-like piece of water. On one side the short wooded spurs and valleys of the Cordillera come down at right angles to the very strand; on the other the open view of the great Sulaco plain passes into the opal mystery of great distances overhung by dry haze. The town of Sulaco itself -- tops of walls, a great cupola, gleams of white miradors in a vast grove of orange trees -- lies between the mountains and the plain, at some little distance from its harbour and out of the direct line of sight from the sea.
