In the past fifty years winds have lost their importance in the eyes of man. Steam now transports him on his ocean voyage. But, by a strange chance, winds in the next fifty years will become once more a potent fac tor in mans movements, in the op- inion of Charles F. Redden, General Sales Manager of the Aeromarine Plane and Motor Company of Key port, N. J.
 At the present time surface winds hinder or help the aviator slightly, accordingly as he flies with them or against them," MT. Redden said re- gently. These areial currents are Of little import sncc. however, for their velocity is never more than a frac- ton of the speed of the plane. Sur face winds will never matter much in aviation.
 Nevertheless as flying develops in the next half century-wind will be of as much consequence as in the days of clipper ships. The winds I mean are those vast currents of air blowing always at two hundred miles an hour or more at attitudes of six or seven mile or higher.
 Although scientists had long sus- pected the existence of these terrific winds, which are due to the rota- tion of the earth, Capt Rudolph w. Schroeder, of the Army Air Service, was the first to prove their exist ence. He reported after the flight at Dayton, Ohio, in which he broke the worlds stitude record, that at one time far above the earth he encoun- tered a wind 220 miles an hour. Al 4 So1 Iix fo of 100 miles an hour he was actually being blown backwards at the rate of 120 miles an hour.
 Above this West to East wind, the scientists believe, is a period of com parative calm, and above this an- other great air current-bIowing in the opposite direction. These winds, I am sure are to play a greater part in mans future transportation, which will be many times faster than it is at present. Since in the eventeen years since the Wright Machine man has ascended so high it is reasonable to assume he will go higher, and that what is now a daring flight will become commonplace.
 Two recent inventions go far to- ward making the conquest of the higher attitudes certain. These are the Super-charges, or turbe e1booster and the variable pitch propeIlor. Both are designed to overcome the difficult ties of flying rapidly in the rarer ai, far above the earth. The super charger or booster is a device which congresses the thin air to sea leve 1 density, fifteen pounds per square inch, before it is fed to the carl UT ator. Motors reuire air just as mucf as do human beings, and without tn device the motor does not develop half it's sea level power.
 | "The other device, the variable | pitch propeller, is a propeller ths blades of which may be turned ir ! flight so that they have a great ol small pitch. This makes it possible l to adjust the propeller to give the

 'The move towards completely en
 closed planes, begun two years az
 in this country when the Aeromar
 inc Company built the first cabi flying boat, is becoming more an more rapid, and soon the plane i ! which the passenger is exposed to tn rush of the wind and bite of the ai
 will be a rarity. The move to talk advantage of these great air current will be slower, but man sooner c later will make use of them, as h has always made use of every fore of nature he has encountered.
