Abstract
IT was noticed in very early times that the wind in the upper air may be very different from what it is on the surface. Lucretius says: “See you not too that clouds from contrary winds pass in contrary directions; the upper in contrary way to the lower.” Bacon advocated the use of kites in studying the winds; but it is only in quite recent years that any systematic attempt has been made to investigate the free air above the surface of the earth. Kites have been flown to a height of four miles, but it is a matter of some delicacy to get even so high as two miles.
