PROBLEM OF PERPETUAL MOTION

Among 1 AuistraMani aiborigines no man stands higher intellectually and im every other way than David Unaipon, who was born ati the Point M'acleay (South Australia) Miissiotn Station, and! still regards it as home (says tihe "South Australian Register"). He has always been a keen student, and a voracious reader of good literature, which mo ' doubt accouinits ifor . his excellent command of English, h:s fluency as a speaker, and his happy style both on the public platform Qiad in ordinary wmversation. 'Miebhanics have appealed most strongly to David, who mamiy years ago set out to investigate the prob- ; lemi of .perpetual motion. Disappointments immumerable came his way, .but' he persevered, and now ! claims that he has evolved an ap- | .pliiamce for '< thar.nessinjg igravitation amd utilising s the power for the driving of stationary machinery. What he requires are funds to enable him to take out a patent, and with the object of raising these he has beguimi a lecturing campaign which, he hopes, will enable himi to address* audiences practically thumigihourt tha State. In the course of his chats, Davlid deals most emtertamingly and interestingly with the legends, customs and. methods of the aborigines in, .the days gone' by, and seeks to impress upon the people the need for "bringing 1 light," through Christianity, to those who are left, and saf-eiffaaa'dlioig ttheir general welfare in the fullest possible degree. In connection with his gravitation, invention, David was asked whether he had demonstrated it in the presence of anybody. He instantly acknowledged that he had not done so. "I know, however, that it:, is all right," he said, "'because I have used' it, -'but the invemtioin is so extraordinary simple that if. it were demonstrated publicly it wrjuild be amanediiately' ayailaible" to everybody, and the opportunity would-be past for patieating it." A few "years ago David • invented it and palt einted a' device \for an indprovemient to tihe handpiece of the ordinary sheepsheairing miaphine—-toanvertirjig, ll the radial into a, lateral (movem.en.-'t;.
