THE grand descent of winds upon the world takes place at the equinoxes. At this period the balance of tropic and pole librates, and the vast atmospheric tides pour their flood upon one hemisphere and their ebb upon another. The signs of Libra and Aquarius have reference to these phenomena.
It is the time of tempests.
The sea awaits their coming, keeping silence
Sometimes the sky looks sickly. Its face is wan. A thick dark veil obscures it. The mariners observe with uneasiness the angry aspect of the clouds.
But it is its air of calm contentment which they dread the most. A smiling sky in the equinoxes is the tempest in gay disguise. It was under skies like these that "The Tower of Weeping Women" in Amsterdam was filled with wives and mothers scanning the far horizon
When the vernal or autumnal storms delay to break they are gathering strength; hoarding up their fury for more sure destruction. Beware of the gale that has been long delayed. It was Angot who said that "the sea pays well old debts."
When the delay is unusually long, the sea betokens her impatience only by a deeper calm, but the magnetic intensity manifests itself by what might be called a fiery humour in the sea. Fire issues from the waves; electric air, phosphoric water. The sailors feel a strange lassitude. This time is particularly perilous for iron vessels; their hulls are then liable to produce variations of the compass, leading them to destruction. The transatlantic steam-vessel Iowa perished from this cause.
To those who are familiar with the sea, its aspect at these moments is singular. It may be imagined to be both desiring and fearing the approach of the cyclone. Certain unions, though strongly urged by nature, are attended by this strange conjunction of terror and desire. The lioness in her tenderest moods flies from the lion. Thus the sea, in the fire of her passion, trembles at the near approach of her union with the tempest. The nuptials are prepared. Like the marriages of the ancient emperors, they are celebrated with immolations. The fête is heralded with disasters.
Meanwhile, from yonder deeps, from the great open sea, from the unapproachable latitudes, from the lurid horizon of the watery waste, from the utmost bounds of the free ocean, the winds pour down.
Listen; for this is the famous equinox.
The storm prepares mischief. In the old mythology these entities were recognised, indistinctly moving, in the grand scene of nature. Eolus plotted with Boreas. The alliance of element with element is necessary; they divide their task. One has to give impetus to the wave, the cloud, the stream: night is an auxiliary, and must be employed. There are compasses to be falsified, beacons to be extinguished, lanterns of lighthouses to be masked, stars to be hidden. The sea must lend her aid. Every storm is preceded by a murmur. Behind the horizon line there is a premonitory whispering among the hurricanes.
This is the noise which is heard afar off in the darkness amidst the terrible silence of the sea.
It was this significant whispering which Gilliatt had noted. The phosphorescence on the water had been the first warning; this murmur the second.
If the demon Legion exists, he is assuredly no other than the wind.
The wind is complex, but the air is one.
Hence it follows that all storms are mixed-a principle which results from the unity of the air.
The entire abyss of heaven takes part in a tempest: the entire ocean also. The totality of its forces is marshalled for the strife. A wave is the ocean gulf; a gust is a gulf of the atmosphere. A contest with a storm is a contest with all the powers of sea and sky.
It was Messier, that great authority among naval men, the pensive astronomer of the little lodge at Cluny, who said, "The wind comes from everywhere and is everywhere." He had no faith in the idea of winds imprisoned even in inland seas. With him there were no Mediterranean winds; he declared that he recognised them as they wandered about the earth He affirmed that on a certain day, at a certain hour, the Fohn of the Lake of Constance, the ancient Favonius of Lucretius, had traversed the horizon of Paris; on another day, the Dora of the Adriatic; on another day, the whirling Notus, which is supposed to be confined in the round of the Cyclades. He indicated their currents. He did not believe it impossible that the "Autan," which circulates between Corsica and the Balearic Isles, could escape from its bounds. He did not admit the theory of winds imprisoned like bears in their dens. It was he, too, who said that "every rain comes from the tropics, and every flash of lightning from the pole." The wind, in fact, becomes saturated with electricity at the intersection of the colures which marks the extremity of the axis, and with water at the equator; bringing moisture from the equatorial line and the electric fluid from the poles.
The wind is ubiquitous.
It is certainly not meant by this that the winds never move in zones. Nothing is better established than the existence of those continuous air currents; and aerial navigation by means of the wind boats, to which the passion for Greek terminology has given the name of "aeroscaphes," may one day succeed in utilising the chief of these streams of wind. The regular course of air streams is an incontestable fact. There are both rivers of wind and rivulets of wind, although their branches are exactly the reverse of water currents; for in the air it is the rivulets which flow out of the rivers, and the smaller rivers which flow out of the great streams instead of falling into them. Hence instead of concentration we have dispersion.
The united action of the winds and the unity of the atmosphere result from this dispersion. The displacement of one molecule produces the displacement of another. The vast body of air becomes subject to one agitation. To these profound causes of coalition we must add the irregular surface of the earth, whose mountains furrow the atmosphere, contorting and diverting the winds from their course, and determining the directions of counter currents in infinite radiations.
The phenomenon of the wind is the oscillation of two oceans one against the other; the ocean of air, super-imposed upon the ocean of water, rests upon these currents, and is convulsed with this vast agitation.
The indivisible cannot produce separate action. No partition divides wave from wave. The islands of the Channel feel the influence of the Cape of Good Hope. Navigation everywhere contends with the same monster; the sea is one hydra. The waves cover it as with a coat of scales. The ocean is Ceto.
Upon that unity reposes an infinite variety.
