RUBGEREXPERT TONEETNU.S. All Phases of Industry Will Be Discussed by World Lead- ers at Philadelphia. Rubber, one of the most active sub- Jects in the automobile world for the past two vears, will come in for far reaching consideration in all of its as- pects at a world raw rubber sympo- slum at the golden jubilee meeting of the Ameriean Chemical Society. to he held in connection with the Philadel phia Sesquic nial Exposition dur- ing the week of September 6 Experts from Great Britain and Holland, the two nations w ar Ppresent ‘control the world rav supply. will addrese the sessions. . A. van Rossem of Delft, Hol . internationally known for his work on raw rubber for the Dutch rubber interests, will describe develop- ments in the technology of rubber on the Dutch plantations search work in progr British Expert Coming. Dr. Henry P. Stevens of London eonsultant for the British Rubber Growers' Association, an investigator who {s ald to have turned out an im mense quantity of important work, is to deliver an address on “Recent De. velopments in the preparation of Plantation Rubber.” which will show the activities of the British investi gators. Ernest Hopkinson, New York, vice president of the United States Rub- ber Co., will discuss the “Botanical and Chemical Developments in the Plantation Industry,” with particular rafererce to the work in progress on the plantations of the United States Rubber Co. The. Chemical Society's announce. ment calls attention to recent expan slon of plantations controlled by American interests Reclaimed rubber, » valuable sub. stitute for new rubber and plaving an important part In conserving the world supply. will be dealt with. by Dr. L. E. Weber of Boston, under the title, “The Present and Future of Re claimed Rubber.” Talk Upon Raw Rubber. W. B. Wiegand, New York physi efst, will discuss from a critical point of view the physical properties of raw rubber and of vuleanized rubber in a paper on “A Comparison of the Phys. ical Properties of Raw Rubber With Those of Compounded Vulcanized Rubber.” “There always is the possibility of producing new substances, not neces- sary similar in properties to vulean ized rubber, which will replace rub. ber for various uses and be superior | physically and economically,” ciety’s statement continued. “This suggestive topic of alternative ma- terials for ruhber is to be presented by Dr. E. B. Spear of Pittsburgh and will doubtless offer an entirely new point of view to many. “With rubber now an indispensable material in industry and daily life, it is of interest to survey its economic status, the present lack of alterna. tive materials and the economic ad- ‘vantages of a native supply. subfect will be discussed by Dr. A. D. Little of Cambridge, Mass “With the growing interest in Guay- ule as a potential source of rubber, it is particularly opportune to hear addresses by G. H. Carnahan, presi- dent of the Continental Rubber Co.. on ‘The Botany and Agricultural Problems of Guayule Rubber.) and by Dr. David Spgnce, vice president of the same organization, on ‘The Chemistry of Guayule.” Africa and Tropical America. “Likewise Brazil and Africa at any time may assume an important posi tion in the growing of rubber, a sub. Ject which will be discussed by Dr. H. N. Whitford of the Ruhber Assoclation of America in a paper entitled “Wild and Plantation Rubbers of Africa and Tropical America.’ Most rubber chemists ‘with this subject. “The subfect of synthetic rubber, which is alwavs of interest, will be discussed by recognized authorities. “In improving the quality of rub- ber a fundamental knowledge of the physical and chemical properties of raw rubber is essential to scientific experimentation study of the physical structure of latex and of raw rubber by means of the microscope, which will be de scribed by R. P. Goodyear Tire and Rubber Co., will contribute toward a better knowledge of the properties of rubber. “Furthermore, it is little realized that X.rays offer a ready and an exact method of studying the ultimate struc- ture of rubber.

FULL INFORMATION VITAL IN AGCIDENTS Mental Upsets Often Prevent Drivers Getting Proper De- tails After Mishaps. Mental upsets following automobile accidents usually prevent the driver who figures in mishaps from getting facts relative to the case that may be of great importance to the court or to an_insurance company This fact is pointed out by the Natio Safety Council. which ad- vises motorists against hesitating to 1l the fnforma- s in the mishap may desire, the scene of the crash until you are justitfied in so doing,” the council ad- motorist who flees after an accident in ‘which-some one has been injured commits a serious of- fense which may land nim in jail if he apprehended. Drive the injured n to the nearest doctor's office or tal and report immediately to an officer or at the nearest police sta- tion.” To st motorists in obtaining full information in case of an accident, the council lists the following details as_vital to the record Name, sex, age and address of in- jured person and other drivers. i Names and addresses of witnesses. License numbers of other cars in- | volved. Exact location of accident (street, house number, etc.). Date, and time of day or night. Weather conditions (rain, snow, clear, dark, etc.). Street conditions (dry, wet, asphalt, brick. ete.). Nature and extent of accident (per- sons injured, damage to property, an- other or your own car, etc.). Circumstances of accident (speed and direction of other vehicles in- volved, were horns used or proper signals given. etc.). Whose fault. A pencil sketch showing as much detail as possible. Did You Know That— City water is safe enough for use in batterfes provided it is pure? Many battery service stations do not use distilled water. An automobile engine always tends to revolve around its crankshaft? This force is referred to as a tortional strain. As a_matter of fact, torque is so great the whole car fends to revolve around its propeller shaft. That it is prevented from doing so {does not eliminate the strain. Oil is a better chassis lubricant but uld not be used unless some pro- on is made to keep chassis bear- ings generously and frequently sup- | plied. performance when ‘Keep vour head and do not leave | I merely as a means of balancing the FLYWHEEL’S REAL JOB. Fills in Gaps Where No Power Pis- i ton Stroke Is Developed. The real function of the flywheel is to carry the crank shaft over so the pistons can complete their three non- power strokes. In the four-cycle en- gine, used universally at present, only one piston stroke out of four con- tributes to the propelling of the crank shaft. The flvwheel is thought of | motor and reducing vibration, but its more important function is to carry | each piston, by momentum, through the exhaust, intake and compression strokes until another power stroke is due. RUST RUINS NICKEL. Leaving Car Out Long Enough to Dry Off Is Damaging. Greatest damage is done to nickel trimmings by rust when the car has been in the wet and kept out long| enough to dry off, for under these conditions the owner believes that the nickel needs no attention, Having dried, he assumes that it will not rust. A few days later he notices that his lamps, bumper and so on are speckled with rust spots highly difficult to re- move. The rough po!shing necessary % to remove the rust does the nickel no good.

We hear a lor about car owners mistakes, and T must admit I talk too much about 'em myself. What we need is a little more consideration for mistakes made by repairers Even a repairer can overestimate his ability.

Here are a few of our weaknesses We have trouble forgettin' the de job we worked on, and often try to give every car trouble the same diagnosis. If we find a squeak comin’ from an unoiled spring that happens to have heen inclosed in a spring_cover, we think all car noises come from the springs and want to throw all covers into the junk heap. We often tell an owner that the job will take less time than we know in our hearts it will, hecause we don’t want to discourage him. We don't figure on interruptions in our work. We have a habit of tearin' things 2 7% 22 2 I 2% makin' sure we have on hand any new parts that may be needed. As a result of this lack of forgsight we often tie up & man's car unnecessarily. We fail to try out a job after havin' e on it. and leave it to the o discover—usuaily while he's trip—that the job fsn't nrop apart without firat 4} to.give the ewner in structions to how to handle the car o that the new parts will give him the best results and o our work will show up as worth while it Carburetor Mixture Stressed. Carburetors can be made to supply safe mixtures or dangarous ones. The carburetor should be adjusted so thar ! stepping on the accelerator will make the car jump out of danger. If step ping on the gas chokes the motor and causes it to slow down, it is as dan gerous as brakes that fail. {SPRING COVERS WRONGED. | Motorizts Often Put Them on When | Leaves Are Filled With Grit. | Spring eovers have heen condemned | unjustiy because anneving squeaks | have been traced to rust between the | leaves of springs.
