As they approached the equator, the breeze kept falling and falling, and the atmosphere became suffocating in the extreme. It was the zone of calms, the ocean of dark, oily waters, in which boats remained for entire weeks with sails limp, without the slightest breath rippling the atmosphere.
Clouds the color of pit coal reflected the ship's slow progress over the sea; showers of rain like whipcord occasionally lashed the deck, followed by a flaming sun that was soon blotted out by a new downpour. These clouds, pregnant with cataracts, this night descending upon the full daylight of the Atlantic, had been the terror of the ancients, and yet, thanks to just such phenomena, the sailors could pass from one hemisphere to another without the light wounding them to death, or the sea scorching them like a burning glass. The heat of the equator, raising up the water in steam, had formed a band of shade around the earth. From other worlds it must appear like a girdle of clouds almost similar to the sidereal rings.
In this gloomy, hot sea was the heart of the ocean, the center of the circulatory life of the planet. The sky was a regulator that, absorbing and returning, restored the evaporation to equilibrium. From this place were sent forth the rains and dews to all the rest of the earth, modifying its temperatures favorably for the development of animal and vegetable life. There were exchanged the exhalations of the two worlds; and, converted into clouds, the water of the southern hemisphere—the hemisphere of the great seas with no other points of relief than the triangular extremities of Africa and America, and the humps of the oceanic archipelagoes—was always reinforcing the rills and rivers of the northern hemisphere with its inhabited lands.
From this equatorial zone, the heart of the globe, come forth two rivers of tepid water that heat the coasts of the north. They are the two currents that issue from the Gulf of Mexico and the Java Sea. Their enormous liquid masses, fleeing ceaselessly from the equator, govern a vast assemblage of water from the poles that comes to occupy their space, and these chilled and fresher currents are constantly precipitating themselves on the electric hearth of the equator that warms and salts them anew, renewing with its systole and diastole the life of the world. The ocean struggles vainly to condense these two warm currents without ever succeeding in mingling itself with them. They are torrents of a deep blue, almost black, that flow across the cold and green waters.
The Atlantic current, upon reaching Newfoundland, divides its arms, sending one of them to the North Pole. With the other, weak and exhausted by its long journey, it modifies the temperature of the British Isles, tempering refreshingly the coasts of Norway. The Indian current that the Japanese call, because of its color, "the black river," circulates between the islands, maintaining for a longer time than the other its prodigious powers of creation and agitation which enable it to trail over the planet an enormous tail of life.
Its center is the apogee of terrestrial energy in the vegetable and animal creations, in monsters and in fish. One of its arms, escaping toward the south, goes on forming the mysterious world of the coral sea. In a space as large as four continents, the polyps, strengthened by the lukewarm water, are building up thousands of atolls, ring-shaped islands, reefs and submarine pillars that, when united together by the work of a thousand years, are going to create a new land, an exchange continent in case the human species should lose its present base in some cataclysm of Nature.
The pulse of the blue god is the tides. The earth turns towards the moon and the stars with a sympathetic rotation like that of the flowers that turn towards the sun. Its most movable part—the fluid mass of the atmosphere—dilates twice daily, swelling its cavities; and this atmospheric suction, the work of universal attraction, is reflected in the tidal waters. Closed seas, like the Mediterranean, scarcely feel its effects, the tides stopping at their door. But on the oceanic coast the marine pulsation vexes the army of the waves, hurrying them daily to their assault of the steep cliffs, making them roar with fury among the islands, promontories and straits, and impelling them to swallow up extensive lands which they return hours afterward.
This salty sea, like our body, that has a heart, a pulse and a circulation of two different bloods incessantly renewed and transformed, becomes as furious as an organic creature when the horizontal currents of its interior come to unite themselves with the vertical currents descending from the atmosphere. The violent passage of the winds, the crises of evaporation, and the obscure electrical forces produce the tempests.
These are no more than cutaneous shudderings. The storms, so deadly for mankind, merely contract the marine epidermis while the profound mass of its waters remains in murky calm, fulfilling its great function of nourishing and renewing life. Father Ocean completely ignores the existence of the human insects that dare to slip across his surface in microscopic cockle-shells. He does not inform himself as to the incidents that may be taking place upon the roof of his dwelling. His life continues on,—balanced, calm, infinite, engendering millions upon millions of beings in the thousandth part of a second.
The majesty of the Atlantic on tropical nights made Ulysses forget the wrathful storms of its black days. In the moonlight it was an immense plane of vivid silver streaked with serpentine shadows. Its soft doughlike undulations, replete with microscopic life, illuminated the nights. The infusoria, a-tremble with love, glowed with a bluish phosphorescence. The sea was like luminous milk. The foam breaking against the prow sparkled like broken fragments of electric globes.
When it was absolutely tranquil and the ship remained immovable with drooping sail, the stars passing slowly from one side of the mast to the other, the delicate medusae, that the slightest wave was able to crush, would come to the surface floating on the waters, around the island of wood. There were thousands of these umbrellas filing slowly by, green, blue, rose, with a vague coloring similar to oil-lights,—a Japanese procession seen from above, that on one side was lost in the mystery of the black waters and incessantly reappeared on the other side.
The young pilot loved navigation in a sailing ship,—the struggle with the wind, the solitude of its calms. He was far nearer the ocean here than on the bridge of a transatlantic liner. The bark did not beat the sea into such rabid foam. It slipped discreetly along as in the maritime silence of the first millennium of the new-born earth. The oceanic inhabitants approached it confidently upon seeing it rolling like a mute and inoffensive whale.
In six years Ulysses changed his boat many times. He had learned English, the universal language of the blue dominions, and was refreshing himself with a study of Maury's charts—the sailors' Bible—the patient work of an obscure genius who first snatched from ocean and atmosphere the secret of their laws.
Desirous of exploring new seas and new lands, he did not stop in the usual travel zones or ports, and the British, Norwegian, and North American captains received cordially this good-mannered official so little exacting as to salary. So Ulysses wandered over the oceans as had the king of Ithaca over the Mediterranean, guided by a fatality which impelled him with a rude push far from his country every time that he proposed to return to it. The sight of a boat anchored near by and ready to set sail for some distant port was a temptation that invariably made him forget to return to Spain.
