0NE IN EVERY 1,000. TIRES ~|S A LITTLE. 0FF IN J. $. FACTORY

The almost complete absence in the tire markets of United States tire seconds" has brought from that com- pany the explanation that long steps forward in the scientific construction of it's tires have resulted in such a per- lection of output that for a long period the number of slightly imper- feet tires coming from the companys factories has averaged less than one in a thousand
 | What few Seconds appear are snatched up eagerly, and as a conse- quence only Ierfect tires appear in the open market
 The scientific methods employed in the open market of tires have two pur- lposes--to make sure that the ma terials are perfect in quality and to make sure that every detail of work manship is absolutely perfect. As a 1,consequence. when tire finally goes | into a mould the various parts fit to- gether with an eXactness that guar antees a flawless. good looking pro- duct
 | Plenty of Inspectors
 | One out of every twelve employees in the factories is an inspector whose duty it is to find flaws, and whose pay in creases as the number of imperfec 1 tions discovered increases. On the more important operations, one out of each eight employees is an inspector. | In the whole course of manufacture nothing is taken for granted. For in- stance, although all the cotton fabrics which form the foundation of the tire carcasses are. built, of the finest ma : terials and are thoroughly inspected 1nn Tir,c~ tn fno ofo xrct when these fabrics reach the tire plants, they are subjected to new ex- amnations. so searching that innum- I;erable small flaws are brought to light The skilled inspectors go over every inch of the fabric and rigid tests are made. that bring out any possible weaknesses.
 Look for Odd Pieces
 Some of the things the fabric in- ,spectors look for are thick and thir places caused by starting and stopping the loom; mixing filling, due to care lessness in winding bobbins; double picks, one yard TUT on top of another beat-up marks, caused by crimp 1T warp threads which are likely to cut the filling threads; wrong ply, les: single threads than standard construc- tion: and oil spots. After the fabric i. coated with rubber. new inspection. take place. Especial pains are taker to make sure that these coated strips of fabric are neither too thick nor thin for the slightest variation from tht standard means imperfection in thu completed tire. So careful is thi. work, that a deviation of a thousandtf of an inch from the fixed specifications results in rejection.
 Visitors to the factories usually finger longer at the scales where tn, long strip of rubber which is to be come the tire tread, is weighed. Thi. rubber. strip arrives at the scales aftel a long jonrey through the various pro cesses necessary to the treatment O

The crude rubber has beel washed and milled and the chemica ingredients have been worked into it and then strips, according to require ment in length, width and thickness | are cut ''''.'' .'' Has Weighty Position The weighing inspector stands a

 as piece after piece goes on the scale and the arm comes into the exact bal ance. the onlooker is forced to open
 mouthed amazement at the uncann exactness of the methods which pro duce such unvarying results. These careful methods of construc tion are making themselves felt in tn
 mileage records of the tires. The ab

 a satisfactory service if they are prop
