YEARS RECORD FOR IMPROVEMENT IN
 AUTO INDUSTRY

One of the best instance of the changes for improvement in the au- tomotive industry that 12 months time can bring is presented by the advance since the 1921 Auto Show in the use of molybdenum steels in automobile construction.
 In the exhibition of one year ago, there were only isolated cases where a few parts of some machines were made of the new alloy steel.
 A comparison of the important place molybdenum occupies in this years exhibit is indicative of a gen eral acceptance of molybenum as distinct forward step in the automo- tive industry.
 Practically all of the more import ant automobile manufacturers have. inentation with molybdenum steel or have completed tests and approved it's use in some or all stressed parts of their machines.
 Business conditions have been such in the last 12 months that curtail- ment has been more or less general in the production of automobiles. This situation has retarded somewhat the actual physical adoption of molybdenum in more care that those in which it is already an element. Many manufacturers who have ap- proved its eventual use have found themselves confronted with large in ventories of other steels and with the necessity of utilizing them before shipments of the new steel could be- gin.
 In the face of such conditions, however, there is a marked increase in the appearance of molybdenum in this years show in comparison to last year.
 c. Harold Wills, with the Wi11s-St Claire, was the first manufacturer to take full advantage the new pro- duct and to announce an an-molyb- denumr car. The claim is made for this car that, because of the unuSu- ally resistant qualities of the type of steel used, a considerable decrease in weight is attained together with an accompanying increase in endurance powers. It is an achievement of this kind towards which autOmotive en- gineers had been working for before the availability of Am arican supplies of molybdenum in quantity made its commercial dSas possible.
 The Studebaker Corporation is among the larger manufacturers who are making use of molybdenum in their cars with results that are said to be most satisfactory.
 One of the best instances Of the value of molybdenum under unusual circumstances is offered by the rec ord Dueseniberg racing cars made in in the modern method of racing on curved tracks, each lap required a driver to accelerate his car four times and to accelerate it four times.
 
 -tum, because of the speed at which racers fly, placed @ tremendous strain on a car. When the weight of a rac- ing car is reduced. less force is re- ouired in the processes of accelera- ton and declaration with the result tfat less strain is eXerted upon parts of the car. The importance of the relation of materials to speed is shown effectively by the success of the Duesenberg molybdenum cars that captured the Grand Prix in 1921 and that carried Jimmy Murphy cover 25O miles in December at a new worlds record average rate. of 110.6 miles an hour.
 The Mack truck makers were among the first truck manufactur- CTS to adopt molybdenum- A Good year truck, made in part of nolyb- denum, crossed the United States in 1921, in six days, Is hours and 23 minutes. a remarkable record for truck travel.
 Manufacturers of parts also have been quick to appreciate the pecul- jar advantages of molybde mum. Hyatt bearings, Parish frames and the products of the Ohio Seamless Tube Go. are among those that now are made of molybdenUn steels. Even motorcycle makers have been listed among the ranks of mo1ybde- mum users, the Cleveland motorcycle being the first mOlvbdenum cycle
