From hence he could see around the horizon.
The western side was appalling. A wall of cloud spread across it, barring the wide expanse from side to side, and ascending slowly from the horizon towards the zenith. This wall, straight lined, vertical, without a crevice in its height, without a rent in its structure, seemed built by the square and measured by the plumb-line. It was cloud in the likeness of granite. Its escarpment, completely perpendicular at the southern extremity, curved a little towards the north, like a bent sheet of iron, presenting the steep slippery face of an inclined plane. The dark wall enlarged and grew; but its entablature never ceased for a moment to be parallel with the horizon line, which was almost indistinguishable in the gathering darkness. Silently, and altogether, the airy battlements ascended. No undulation, no wrinkle, no projection changed its shape or moved its place. The aspect of this immobility in movement was impressive. The sun, pale in the midst of a strange sickly transparence, lighted up this outline of the Apocalypse. Already the cloudy bank had blotted out one half the space of the sky: shelving like the fearful talus of the abyss. It was the uprising of a dark mountain between earth and heaven.
It was night falling suddenly upon midday.
There was a heat in the air as from an oven door, coming from that mysterious mass on mass. The sky, which from blue had become white, was now turning from white to a slatey grey. The sea beneath was leaden-hued and dull. There was no breath, no wave, no noise. Far as eye could reach, the desert ocean. No sail was visible on any side. The birds had disappeared. Some monstrous treason seemed abroad.
The wall of cloud grew visibly larger.
This moving mountain of vapours, which was approaching the Douvres, was one of those clouds which might be called the clouds of battle. Sinister appearances; some strange, furtive glance seemed cast upon the beholder through that obscure mass up-piled.
Gilliatt observed it closely, and muttered to himself, “I am thirsty enough, but you will give me plenty to drink.”
He stood there motionless a few moments, his eye fixed upon the cloud bank, as if mentally taking a sounding of the tempest.
His galérienne was in the pocket of his jacket; he took it out and placed it on his head. Then he fetched from the cave, which had so long served him for a sleeping-place, a few things which he had kept there in reserve; he put on his overalls, and attired himself in his waterproof overcoat, like a knight who puts on his armour at the moment of battle. He had no shoes; but his naked feet had become hardened to the rocks.
