(6.8 sq. m.). Wire out, 5,500 ft. (1,676 m.); at maximum altitude, 4,200 ft. (1,280 m.). Light fog prevailed at the beginning of the flight, but it soon became dense and so continued until the kites were landed. The wire, especially that near the kite, was heavily coated with frost when reeled in. At 8 a. m. a moderate depression lay over lower Canada, and a slighter depression extended from Georgia to eastern Kentucky. The barometer was comparatively high off the middle Atlantic coast and over the Rocky Mountain region. December 19, 1907.--Four kites, having a total lifting surface of 251 sq. ft. (23.2 sq. m.), were used. Wire out, 23,700 ft. (7,223 m.); at the maximum altitude, 21,000 ft. (6,400 m.). When the flight began the sky was partly covered with St.-Cu. clouds from the northwest. These gradually disappeared, leaving the sky clear during the latter part of the flight. High pressure covered practically all of the United States, with centers over western Tennessee and Wyoming. Pressure was low north of the Lakes. December 20, 1907.--Two kites having a total lifting surface of 142 sq. ft. (13.1 sq. m.) were used. Wire used, 7,500 ft. (2,286 m.); at the maximum altitude 5,900 ft. (1,789 m.) of wire was out. St.-Cu. from the west covered the sky during the entire flight. At 8 a. m. pressure was high over the country, except over Utah and Arizona and in the upper Lake region. The eastern high area was central over Virginia and North Carolina. December It, 1907.--Two kites, having a total lifting surface of 136 6q. ft. (12.6 sq. m.), were used. Wire used, 10,000 ft. (3,048 m.), at the...
