Few are aware that the rectangular kite of the weather man was the forerunner of the aëroplane of the aviator. In 1903, while directing wireless experiments in the sending of messages at Roanoke Island, North Carolina, the writer saw the Wright brothers, or their representatives, lying flat upon the lower planes of what appeared to be Weather Bureau kites and gliding in the air from the top of the sand dunes. This was the beginning of real flight by man. The ingenuity of the Wrights transformed the weather man’s kite, strengthened it, took out the ends, hitched on a rudder, and when the petrol engine had developed sufficient power with a given weight, installed it, and flew. In the future the meteorologist and the aviator will be closely associated. With a sufficient number of weather observations made by aviators simultaneously and well distributed over the United States it will be possible to construct a daily weather map on some high level—say the three-mile level—similar to the map now based upon sea level. The pressure, temperature, wind direction, clouds, and rainfall would be recorded and charted for the upper region clear across the continent. Three miles is about halfway to the top of cyclonic storms and probably in the region of greatest activity. More accurate forecasts would be possible by the study of this additional weather chart. This coöperation of the bird man and the weather man in studying the geography of the new air world will mark an epoch in meteorological science as far-reaching in its consequences as were the discovery of the barometer by Torricelli and the uncovering of the principles of the thermometer by Galileo, the former of which was not known until more than twenty-three years after the landing of the Pilgrims at Plymouth Rock. Thus swiftly does the mind of man to-day explore the hidden recesses of nature’s mysteries, and with each conquest carry itself to a higher realm of existence. In the not distant future, more storm warnings may be issued by the Weather Bureau for ships of the air than for those of the sea, for the navigation of the air must play an increasing and important part in the coming activities of the world. Science is becoming so skilled in the harnessing of the forces of nature to man’s desires and in the development of mechanical appliances, that it is reasonable to anticipate the possibility that long-distance travel over land or ocean ultimately will be almost entirely confined to the air.
