longer life of this important part of the cars. Leaky radiators are the bane of car operators as, frequently are frozen ones. We hear much of so- lutions to prevent damage from freeze ing and we also know that the ordi- nary radiator is comparatively short lived. In certain sections of the coun- soon cut the ordinary steel radiator to pieces. Radiators must be made thin in order to secure the necessary cooling for the waters that circulate about the cylinders and this naturally makes them weak in structure.
 Better Radiators emanded
 There has been a demand for bet ter radiator, one that will hold to- gether longer and be more substantial as we'll as of greater cooling eff. ciency. Such one, we believe. will soon be announced.
 There are going on today experi- ments at the New Cornelia Copper company's teaching plant, at Ajo. Ari- zona, to determine if a copper radia- tor can be manufactured. One of the biggest manufacturers of radiators in the United States is cooperating with the engineers and chemists of this copper company in the attempt to make a radiator of copper, well real izing that if this can be done it will result in the establishment of a large and profitable industry. This single manufacturer. figured on his present production of radiators, would con- sume more than 15,000.000 pounds of copper a year, and if the copper ra- manufacturer, looking for the best, will want to use it.
 The copper radiator has more than twice the radiating qualities of the steel, so that a radiator, to give as much cooling to the motor as the one of steel would not have to be one-half as large as the latter. It could be made so as to fill in the car space by making it thinner. It would not be broken by freezing water as readily as the iron radiator in that copper would stretch far before cracking. It would be of considerably less weight than the iron radiator, making car steering easier and reducing the dead load that would have to be carried.
 Made One at the Plant
 James Potter, who is plant superin- tendent at the New Cornelia property, an engineer of we'll known ability, made copper radiator to prove it could be done. He took sheets of cop per of the desired thickness that had been made in tbe electrolytic tank, at the plant, and he sheared these into the required shapes to form the body of the radiator. putting them together by touching with solder here and there and then suspended the form in the electrolytic tank and plated the entire surface, making it water tight and rigid. He made the copper tubes for connections. He proved that in this crude way he could make a radiator that was practical.
 He bought radiator of small-type car, in order to get the pattern. and he paid about s52 for 1t. His copper radiator, when finished, weighed 25 pounds, so that. at the price he paid for the iron one, he would be getting about $2 pound for his copper. And if the copper radiator can be made for a price to meet the one of steel, then will not every known automobile own CT, or prospective owner, want one? mand it, particularly if the cost be as low as for the iron or steel radia. tor. This copper radiator was exbibi- ted at a meeting of the directors of Calumet & Arizona Mining company and the New COrnelia Copper com pany. held at Warren, Arizona, on the 11th of April.
 Another group of men are also ex- perimenting at the plant on the man ufacture of various kinds of articles to prove their process is practical. They are from New York and have been engaged in experiments for a year or more, and are now making in New York certain articles for the mar ket. photograph parts being one of their products. The process is secret and the articles made in the solution tanks of the teaching plant at Ajo to prove that this eau be done. Previous to this trial quantity of the solution had been shipped to New York to this concern engaged in manufacture and was pronounced ideal for tho purpose
 No Limit to Variety
 If this process is what the inveu tors claim then there is no limit to what can Do produced in this way. There remains to be demonstrated Mhat thp CoSt WiIl Inc Radiators fOr
