RADIUM ORE BROUGHT OUT OF ARCTIC WILDS BY PLANE

Popular Mechanics Radium-bearmg ore is now being brought out of the Arctic regions by airplanes. ll.e imnp ships whieh carried in the minlng equipment to obtau: the oie. The Arctic riiciiuni fi6j_d_ is on thc $hores of Great Bear luke iyid the rock is bcing transport«d from thero by the ton nearly 3,000 niilea by air, water and rall to a factory at Port Hope, Ontario, where chemists extract this most preeiuu» umieiai whieh aells for $70,000 a gram or about $2,000,00 au ounee. Opening of the AvcUc radium field, has provīded a iiew and lesjs Cftstly suurce for lhis mineral> formerly mined mostly iv the Belgian Congo. Ea4lum rock was found on the shores of Great Bear lake three years ago and now the region has mine railways, ore compressors, worltshops, lōg c«Mt>ins, sfcores l airports an<3 radio stations. Machlnery ls belng brought in by air month after month for, besides the radium ;v«k, the region is rieh in siiver, gold and copper. At Port Hojk a method of extracting radium was developed whieh cuts the time from six to three mouths. Thls fact a,nd the higher radium eontent of the Arctic ore are the main factors whieh are expe.ted to make radium available to cancer Buflerers in hospitals at lowe^eoal. Oreat care must be taken in handling the mineral, for even the ore taken from the mines f ts likely to damage the skin. Heat and light emI anations trom the ore are blown away by elee!:fcric tws in the extracting plant. Three tons of chemicals are required to procure radium from a ton ol ore, and every solution and residue is treated over and over to derive every particle of radium concentrate. The total output of the plant a& present U Qnly about half a gram a monlh. Onee the pure radium i? obtal,necifxt is packed in platinum needles contalmng one-thousandth ot a gram, the needles are seald with gold and officially certtfled, ready to be shtpped to the | market or to hospitals for use in treating cancer. ! Chemical Raises Fire-Hose Pressure f Popular Science Monthly t Boosting water pressure for fire-fighting i p»rposes without the use of pumps was feat d§monstrated at Nqwark, N. J., the other day. The stunt, accomp!ished by placīng chemicāls In ' the water lines, is expected to prove a boon to -firemen when combatlng blazs on the outskirts af cities and other districts where ,the water | presaure drops too low to give the hos| stream jsujficlent force and range. 1 Caryed Near Completion Popular Science Monthly Cufctipg into solid granite on a 300-foot cliff, workmen under the direction of Gutzon Borglum ; famous American sculptdr, are iiow putting the"'finishing touches on the HO-foot head of George Washington whieh will form the eenter of tbe scutptured group in the Black Hills mountain - top m<?morial in South Dakota. In speclaUy-designei saddles, the men are lowered down the face of the cliff by winches to cut away the rock with pneumatic drills and hammers. To the right of the sculptured figures, a 500-word history of the United States is to be cut into the granite in letters three fet high. —i-t-i — No Fei*derB on New Auto Popular Science Monthiy An unusual automobile, now being manafactured in Colorado, haa a front axie that arches completely over the englne, whlle the body extends the whole width of the /enders so that sep&rate fenders outside the body are not necessary. The width of the car makes it posslble for an ordinary adult person to sleep crosswi§e in it. The drive is on the front wheels and the design of the body ls ultra-modernistlc.
