 VERY IMPORTANT
Copper Today Is Mainstay Of All
 Electrical Work

Washington |. lC, Dec. -S Tine quincy copper mine of northern Michigan. recently the scene ot an air blast th, damaged the .9-year- old shaft, lies in one of the oldest copper mining regions iu the United States" says a bulletin from th" Washington, D, (. headquarters ol the National GeoErapmr society.
 In colonial days. copper Was talk en in small quantities from deposits along the Atlantic soaDoarl. but ii Nas ! shipment of copper orc from the Michigan deposits 10 the east n i>45 that marked th" real beginning Q. our copper mining industry, Now We produce more copper than tac rest of the world combined,
 Because copper is widely uscd in the electrical field it is called tE' electriciau's metal continued ,n" bulletin. Wherever one sees electric lights and the use of electric power, there is copper Pur" copper drawn into wire is hidden in the walls ol modern homes, and in electric irons and stoves, ana in the motors ot electric vacuum cleaners. dIsbWast- CTS. and refriEentors. lu som. cjt- les one is literally sandWiChCd be- tween copper wire Millions ot Wiles of underground cable and overhead wires carry tho click of the tclc- graph ky and the sound of the human voice.
 The copper wires of one of our telephone systems would encrcle the world at the Equator moro than c. 900 times. One of our telegraph companies operates over more than q million miles of copper wire and owns IS copper-ladcn cables that connect the United States with Eu- rope and the islands of the Atlantic.
 Copper wire made possible the re cent inauguration Of the transatlan- tic telephone service and the com munication of the sos. signal that saved hundreds of lives when the Italian steamship Mafaida Was wrecked off the Brazilian coast Ra- do instruments, with their copper wire connections and coils, arc en- tertalninC the world daily,
 Copper Alloys Used
 Pure copper is too soft for many purposes but alloyed with other metals it is widely used. Bronze Is copper and tin. Brass is copper and zinc. Gunmetal is copper, tin and zinc. Each Of these alloys are moro than half copper. Copper is also alloyed with many other metals, ln- cluding gold and silver.
 "Disregardne the use Of copper for electrical purposes, under its real name and those of it's alloys. copper is seldom out of sight or reach of tho average man in this country. He may sleep under 2 copper roof in a brass bed and be awakened by an alarm clock with brass works. While dressing he may sit on q chair tha, sis held together by brass screws and pull on his shoes that have hraSs .yrlcts and perhaps. brass nails II ] nc ;olcS. He may turn a brass knot Tp open the doors in his homo. dra \ water from brass faucet leadina from brass pipes, and dry his hands ron a towel from q brass towel rack 1hile the curtains at the windows Nang from brass curtain rods. Ills food may be grown with the help of farming implements containing cop per and it's alloys. and cooked Tn tropper kitchen utensils.
 If he uses his automobile or 2 street car 10 go to office. he rides in either of two vehicles that are i'm portant copper consumers. On his way to town perhaps he will pass a bronze statue or two and shoW-win dows that are cncased in copper. If he draws coins from his pocket to make a purchase. he handles copper even though he has no pennies for all of our coins. including the gold pieces, contain copper. The money may finally find it's way into some merchants cash register containing copper and later pay water taxes according to the reading of a cop per meter
 Tn his office he talks over 8 brass telephone instrument. uses brass pins and paper clips. and with brass pens, and q pencil with brass band. may write on stationery that has been engraved from copper plate. A b~ass-hladcd fan keeps him cool in the summer and the brass fittings of tho heating system help to keep him warm in tho winter.
