]. WILLIAMS OF DOUGLAS THE
 INVENTOR.
An English Aviator Has Demonstrated
 Its Excellence.


 Among the belated corners to the aviation meet were E. P. Grindell and J. Williams, of Douglas. who arrived in the city yesterday. Mir. Williams did not come as a mere spectator but as an expert in search of new ideas. for he is an aeroplane constructor himself.
 He is an Englishman and for the last eight years he has held license from the British government as an aviator, or more definitely. as a ''qual- flied pilot" They do things different Iy in England While in this country every boy may be an aviator just as he may, be president sometime If enough people vote for him. on the other side of the water no man may pursue a recognized calling. dangerous to himself or to others unless he can show to the authorities that he has fitted himself for it.
 While in England, Mir. Williams had nothing to do with aeroplanes but was a pilot for dirigible or spiral: balloons. He was, however, student of the air, and airships of all kinds.
 About six monthS ago. after coming to this county he finished at Douglas a monoplane of the Bleriot type but so different from the Bleriot that he has secured patents on several features of it. His purpose in coming to Phoenix was to study at close range the Cur tiss machines.
 His machine is equipped with mo- tor and he has made frequent quiet flights in the vicinity of Douglas. Be- fore he secured the motor he had so much confidence in his airship that he performed daring trick success fully.
 The machine was taken to the sum- init of a precipice which looked al- most vertically upon a plain 200 feet below. Several assistants. propelled the machine by hand power along a runway toward the edge of the preci- pice It rose in the air before reaching the edge and went over. Before it got rightly into action it dropped about forty feet when MT. Williams brought it under control. It then glided easily to the plain--A mile dis tant from the foot of the pricipice. Ii did not, however, glide along an. in- clined plane but "switchbacked": that is, it moved steadily downward with an undulating motion. due to the con- formation of the planes.
 MT. Williams believes that the mon- oplane is the coming machine Its lifting power has been demonstrated to be greater The ordinary bi-piane | ho tn. n hal pounds to the square foot, though the Wright machines, which are by far the best of that type, do a little better than that The Bleriot lifts five pounds: the Latham four and a half and Mr. Williams four and half pounds.
 One of the features of Mir. Williams machine is the rear control, which for all purposes is the best.
 He has no doubt ef the ultimate success of the aeroplane but that will depend upon the development of the motor. There must he something quite different from the existing mo- tor. though the eight cylinder engine of the Hamilton machine is the best. MT. Williams said. he had yet seen. Iho ONH iE lol tApti purposes with an engine from Buick automobile. the flywheel having been removed and replaced by the propeller But no type of gasoline motor yet devised will do. The consumption oi gasoline Is enormous and much of 1t is wasted. single explosion is suffi- cient to produce one revolution of the propeller, but there are in all motors in use three or four explosions to the revolution so that probably three fourths of the gasoline is wasted. II is fact. too that the motors now used in aeroplanes require greater weight of lubricating oil than they do of gasoline. The oil pumps are re- quired to be working rapidly and con- tinuodsly.
 The Wright brothers. having solved the problem of the planes. are. now bending their energies to the solution of the motor problem and they are said to be making progress satisfac. tory to themselves
 Edison is also working on ar aero plane motor along an entirely new line. Mir. Williams said that while the. principle of it had not been ii- vulged it was understood that the power is to be furnished by a tape charged with nitro glycerinc at reg. uiar- intervals. running through the cylinder so that it will produce reg ular and rapid explosions. --e MT. Grindell said that the business men of Douglass have great faith. ir the future ot the Williams monoplan, { and that next week an aero club will be organized there for the further de. veiopment of it. Probably the firsi move will be to install an eight-cyiin. der motor similar to that used b,
