A night of calm, when sleep is well-nigh impossible in the sultry, muggy air, may be followed by a day of blazing sun and an oily swell from the south'ard, connoting great gales in that area of ocean we are sailing toward or all day long the Elsinore, under an overcast sky, royals and sky sails furled, may plunge and buck under wind-pressure into a short and choppy head-sea.
I could see the fine gauzy threads of the fall's filmy border by having the light in front; and wishing to look at the moon through the meshes of some of the denser portions of the fall, I ventured to creep farther behind it while it was gently wind-swayed, without taking sufficient thought about the consequences of its swaying back to its natural position after the wind-pressure should be removed.
Ventnor crouched lower and lower, eyes shielded behind arms folded over his brows, straining for a glimpse of Ruth; Drake crouched beside him, bracing him, supporting him against the tempest. Our line of flight became less abrupt, but the speed increased, the wind-pressure became almost insupportable. I twisted, dropped upon my right arm, thrust my head against my shoulder, stared backward.
They did not learn till later that Venus's day is a little less than twenty-five hours, and therefore, since they had approached her near the equator, the wind they had encountered was moving at nearly nine hundred miles per hour! Bit by bit, though, the cube answered to the wind-pressure.
It was good again to feel the Elsinore yielding to the wind-pressure on her canvas, to feel her again slipping and sliding through the water in an easy sea. Hidden by the darkness, clasped in each other's arms, we talked love and love plans. Nor am I shamed to confess that I was all for immediacy.
The object was to give the air an uninterrupted flow instead of allowing it to be broken up into eddies behind the head of the pilot, and it also provided a support against the enormous wind-pressure encountered. This true stream-line form of fuselage owed its introduction to the Paulhan-Tatin 'Torpille' monoplane of the Paris Salon of early 1917.
Released from the wind-pressure on her strong side, which had somewhat steadied her, the ship now rolled more than she had done in the trough, and with every starboard roll were ominous creakings and grindings aloft. At last came a heavier lurch, and both crippled topmasts fell, taking with them the mizzentopgallantmast.
A snowy shag of whiskers came tossing down through the air and fell in his lap. It was Quimbleton's beard, torn from its moorings by the tug of wind-pressure. Bleak thrust it quickly in his pocket. As the great plane passed over the head of the parade, flying dangerously low, every face save that of the iron-willed Bishop was turned upward.
The natural action of the wind-pressure takes the paper along the string, and so up to the kite itself, no matter how high or how far it may have gone. In the early days of this amusement Edgar Caswall spent hours. Hundreds of such messengers flew along the string, until soon he bethought him of writing messages on these papers so that he could make known his ideas to the kite.
Alfred Craven, chief engineer of Public Service Commission, New York, and formerly division engineer in charge of construction work on Croton aqueduct and reservoirs. From the American Aeronautical Society: Mathew Bacon Sellers, director of Technical Board of the American Aeronautical Society and the first to determine dynamic wind-pressure on arched surfaces by means of "wind funnel."
