Hall, loen I rep resentative of the company, an nounced Saturday. The company operates planes on lally northbound and south hound schedules over the 1 04-mile air way between Seattle, Medford and Kan Dietio, carrying mall, passen gers and express from one term inal to the other In twelve and three-quarters hours. Hall said that the route was started four years ago as an air mail line, and planes powered with 90 horsepower engines were used. The airway was undeveloped, and the first lights fur night flying were installed drover Tyhr uiui other pilots, who carried the bea cons to the desired locations in Ford cars. ' Airway I)evtlK'il. In IflliS the company was taken over by the Hoeing interests, which also operate the Chlcago-Oaklaud-Kan Francisco mail-passenger line. The airway haH been completely lighted for night flying by the de partment of commerce, with pow erful airway beacons Installed at lu-inlle intervals and lighted emergency landing fields estab lished between the terminal air ports. , The newest Improvement on the Jtacific Air Transport route, ac cording to Hall, is the installation of the two-way radio telephone communication system between the ji In iuh in flight and operators at eight ground statlor.a located on the line. One of these pow erful transmitting and receiving stations is established at the Med ford airport. Hy meons of the radiophone, the P. A. T. pilots are always In voice communication with the ground station operators, receiving weather reports furnished by the U.

Remarkable Earl Aircraft Motor Displayed at Airport; Medford Men are Interested One of the most sensational de velopments of the present era of aviation development is claimed to he the new Earl engine, a distinct departure from the umial run f aircraft power plants.

This engine has over 300 less partH and can be manufactured at a cost per horse power far below the present typea of aviation en gines now in use. Mr. Karl, while running tests for the government in 1917, and hav ing in mini) the difficulties encoun- Camshaft of (lit new tered in adapting the automobile engine to aircrafe use. he conceived the idea of disregarding all existing type of engine and allowing the. specific requirements of aviation to dictate the deslg n of ltd power plant. With this in mind, he set mit to discover whnt form such an engine should have' to comply with the laws of aerodynamics that con trol flight. After drafting on pa per several forms of cam, he rec ognized the advantages of tho four-point circular cam for appiy- Ing the power of exploding gas to i the rotation of the propeller.

Tomorrow sees the dedication of a finished airport which would be a credit to a great metropolis. A splendid airport, a splendid service with Boeing planes and pilots, whose average flying time is 4500 hours, give Medford a favored place on the air map. . The airplane services of Pacific Air Transport, one of whose important sta . tions is Medford, connects this city with the great air mail-passenger net work of 170 cities in forty states. 0 "Ladies of Leisure," at Fox Rialto an?"?-.
