NOTHING TAKEN FUR GRANITE BY
 MAKERS IF CARS

The astonishing thing about a good modern automobile is the way it stands up and gives service under every possible road condition, in every part of the world. Rough roads, hills, mud. sand. only seem to bring out the cars | inbuilt stamina. But, to> the owner who sits complacently behind the wheel, free from the worry of frequent mechanical difficulties, there is sell | dom thought as to what is really back of the cars goodness.
 Yet this quality does not just hap pen-there is reason for it.
 Automobile manufacturers take nothing for granted. That is, those recognized leaders who have created and consistently maintained a reputa- tion for quality, accept no ones say so when it comes to the materials that enter into the construction of their cars. They build longevity and ser vice into their cars by making sure in ! advance.
 Begins With Material
 Some sage has said that the training of child should begin with it's grand | parents. Automobile engineers believe that the inspection of car should be- gin with the raw material.
 The Studebaker corporation, one of the worlds largest and best known manufacturers of automobiles, ob- tains surety of manufacture partly from exact engineering calculations, partly by scientific tests in wonderful chemical and physical laboratories and partly by exhaustive road tests.
 Studebaker has invested a large for tune in it's laboratories and equipment The research and chemical laboratories for instance, occupy nearly 15,000 square feet of floor space and employ a large force of skilled men, each man | holding his college or university de- gree. And here it is interesting to note that these Studebaker laborator- | ieS are larger and more completely equipped than many of the universi- ties from which the men employed graduated.
 Put to Severest Test
 In the chemical laboratory materials. such as steel bar stock, brass, bronze babbitt and cast iron are carefully analysed and check with specifications from the engineering department. Any deviation from original specifications means immediate rejection. Steering knuckles, transmission and rear axle gears, steering arms and other vital parts are regularly sampled and checked in the mechanical laboratory to see that production is always up to standard. The metallurgical labora- tory tests the heat treating of steel un- der microscopic enlargements from samples which are taken after each heat treatment.
 Specialized experts in the phyiscal laboratory test finished parts for strength by special machines which ex- ert crushing, twisting and pulling ol bending strength sufficient to break any finished part. Three of the latest type electric power absorption dyna- mometers, measuring power up to 1O( horsepower through a speed range o1 4000 revolutions per minute, arc operated by Studebaker in the dyna- mometer and mechanical departments
 Studebaker's research laboratory maintained at great expense and em. ploying many scientific men of note is fully equipped for scientific worl : along original lines. The object anC duties of this department are to in. t vestigate, analyze, and develop new ideas toward determining their rela ;. tive merits and resultant commercial value.
 Covers All New Models !" The work done in the experimenta e department covers the necessary WOrl If on all new models and special appara
 tus, the inspection of sample of al " purchased parts, such as dies. castings e motor parts, guage, etc. These out : side parts, of course, have been rigid
 ly inspected and checked up by thei
 makers before delivery to Stakeholder. IS But Stakeholder engineers take noth IS ing for granted-they insist upon
 thorough inspection under their ow '- eyes to ascertain whether the wor
 has been accurate and up to Stude Is baker standards. This department }; also used for the purpose of conduc t. ting road tests to evaluate and chec ,r up laboratory results under actuf al road conditions.
 n Tests on the road cover the uues l. voted largely to war activities. tn so | WOmanc' olnh rxuiu bo1J ;+.
