14 RUBBER PROBLEMS TOBEGIVEN STUDY Experts of World to Attend Symposium in Philadel- phia in September. Leading rubber authorities of the world will discuss problems of vital interest to the motorist and to the in- dustry as a whole at an international symposium on raw rubber to be held in connection with the golden jubilee of the American Chemical Society in Philadelphia Described in the official announce- ment of Chairman John M. Blerer of Boston “the biggest event in the history of the society’s rubber di- vision,” the symposium will deal with new knowledge affecting the results of botanical, chemical, technical and engineering research in this country and abroad. Prominent rubber tech- nologists and executives of the indus- try will reveal raw rubber develop- including scientific progress in plantation rubber industr; in wild rubber, South American and African; 4 synthetic or artificial rubber, t ich commercially scientis are uniting.

The basic idea of the Philadelphia s um, planned as one of the scientific gatherings of the Ses. quicentennial International Exposition, is, according to the chairman, to pre: sent new facts and ideas and not to review work already known, and in- formation which is common knowl- edge or which can be readily obtained elsewhere. He concluded: “International experts will confine themselves to new information and data which they will present in detall and discuss critically.

A favorite trick of Washington motorists, and a thoroughly asinine one, is that of blowing the horn vocif- erously when it Is plainly evident that all the horning in the world won't remove the cause of the hold-up or congestion. This honking, lke that cf geese, merely serves to more completely befuddle the snarl and the reason or reasons for it, or angers them to the extent of staying put just for spite. And the observer is led to the conviction that such healthy spite is fully justified. It seems incredible that an other wise intelligent group of _persons would perform in the manner de- seribed, and yet it happens every day —many times every day. xt time a big truck, not in the least desirous of making a nuisance of itself, but merely trying to execute a legitimate mission, backs up against the curb for a minute or so to dump off a load of dirt, thereby holding up a stream of cars, lend an ear to the idiotic screeches set up. A perfect babel of noise, and those making it seem to do it just to hear their horns blow. The motorist who uses his head even on rare occaslons knows ft is psychologically true that the driver of that truck will not hurry when he hears those insistent and insolent horns, but, on the other hand, that he will figuratively thumb his nose at the stream of cars by taking his own good time. There is a definite time and place for horn use and the sooner the rank and file of Washington motorists find it out the more effective those same horns will become.

Why the automobile editor shot his 3.year-old son when the little fellow aid he wanted to “drow up and be an auto editor” has come to light in the diary of the former, who bought him- self a used horse and a four-wheel buggy and drove off the Brooklyn Brid, The self-explanatory excerpts follo Monday, 9 a.m.—"“The annual Mole Hill economy run, one of the most grueling stock-car tests in America, was won this year by the Blaz Eight in record time. The car used but one gallon of gasoline on the terrific 200- mile grind.” 10 a.m.—"“The Wham Four, making but one stop, won this year's Mole Hill run, one of the most grueling stock-car tests in America. The Wham, in establishing a new record for the 200-mile grind, used but one quart of gasoline.” 2 pm.—“The Woof Six, burning but one pint of gasoline, was triumphant last week in the Mole Hill run, the most grueling stock-car grind in America. Three thousand other stock cars of various makes competed.” 4 p.m.—"A big yellow Waffle Twelve roadster was victorious this year in the grueling Mole Hill run, establish- ing a new record for this greatest of American stock-car tests. It carried 12 passengers, one of whom drove while the others manned the sun com- pass, which 1s one of the new features :’hlll; makes the Waffle a leader in its eld.” 5 p.m.—"There will be no Mole Hill run this year, the Mole Automobile Club announced this afternoon. The event, which usually is held next month, failed to attract any entries to gate“und the club decided to aban- on it.” Juggling the Figures? Motordom appears to be sorely in need of accurate statistics regarding production of cars and trucks. There are two agencies at present concerned with compliling of these figures, the United States Department of Com- merce and the National Automobile Chamber of Commerce, but—— Wall Street makes part of its mil- lions by the encouragement or dis- couragement which printed statistics create in the investor's mind. That may explain the juggling of produc- tion figures. A recent piece of news, credited to the Automobile Manufacturers’ Assocla- tion, mentions 449,173 cars and trucks as representing the total of production of motor. vehicles for the United States and Canada. “This compares,” reads the item, “with 449,677-in March and 359,976 in April, 1925. One of the N. A. C. C. reports for last year's activi- ties in the industry places April, 1925, production at 439,117. A mistake in the recent item? Per- haps. The figure for April, 1926, ac- cording to one of the automotive trade publications, is 439,124. Figures can be, and frequently are, juggled for a purpose. This juggling is done malinly by questionable stock brokers who have something to sell or who want to buy when others are frightened into selling at a sacrifice. This reflects upon the accuracy of the Chamber of Commerce and the De- partment of Commerce, and points to the crying need for stricter general observance of accuracy in published statements of production figures. To show a production figure for April last year that is much smaller than it really was may deceive many investors, and make them think there has been a much larger increase in business than actually is the case.

How- ever, in practice this is a poor plan, for, should the car start to coast backward the wheel could be shaken into a straightaway position very easily. If the wheels point to the curb, on the other hand, the car will coast back a few feet and then run into the curb in such a way that the right rear wheel is jammed. Not being a steering wheel, it remains in that position and keeps the car sta- tionary. Press on the service brake pedal while pulling on the emergency brake. Often the car is moving slightly while parking, with the result that sudden application of the emergency brake, which operates on the propeller shaft, will cause the car to rock backward and forward. This merely inflicts a little more punishment on the uni versals and the gears. If the service brakes are set, however, the propeller shaft is at rest and application of the emergency will not strain the shaft and its couplings. Faot Worth_—f:membering. ‘When troubled by uneven front tire wear, suspecting misalignment and yet finding no other evidences of such a condition, why not the next time try another set of front tires with a different kind of tread?” One owner tried this and found there was nothing wrong with the wheels. The original tires merely were subject to a peculiar tread wear. What's the Answer? 1. Is engine power directly propor- tional to engine speed? 2. Are brakes more effective when the car is backing? 3. Which is least to be desired: An overpowered car or an underpow- ered one? 4. What are the three units com- prising the current and voltage supply in the automobile? 5. How does most of the raw gaso line get past the pistons?

UNRIVALED AUTOMOBILE TOURS YIELD HEALTH AND HAPPINESS (Continued from Thirteenth Page.) White Mountains, the Adirondacks and along the New England coast, or down the Jersey coast to Atlantic City and Cape May, thence to Phila- delphia, Baltimore and the National Caplital are trips that will linger long in the memory of those persons for- tunate enough to be able to take them. Touring In Virginid. ‘While the Berkshire hills have been characterized as the most delightful touring place in the United States— more nearly attaining the ideal of the majority of motor tourists—the most interesting touring ground in America lies to the south of Washington, just across the historic Potomac. It is Virginia—the Old Dominion. Virginia is dotted with battleflelds and historic towns. There are Fred- ericksburg, Petersburg, Richmond and Winchester—towns and cities of in- tense interest. Memorable battlefields are those of Seven Pines, Bull Run, the Wilderness, Cold Harbor, Five Forks, Chancellorsville, Spotsylvania and many others. In the State are Old Point Comfort, Newport News, Norfolk, Jamestown, Hampton Roads and Staunton, birthplace of President Wilson. But paramount in interest for all Americans are these: Yorktown, where American inde- pendence was won when Lord Corn- wallls surrendered to Gen. Washing- ton in 1781 Appomattox, where, with the sur- render of Gen. Lee to Gen. Grant, was closed the saddest chapter in Ameri- can history. Mount Vernon, where may be seen the tomb of the Father of His Country. Practically every point of interest in the State is accessible by motor car, but Virginia roads are not uni- versally excellent. However, much highway improvement is under way, and the time is not far distant when all the highways of the Old Dominion ‘will be gdod, and the enchantment the name Virginia holds for the average American may have full and unre- stricted play. Car Makes All Accessible. * To go on and tell of the things and places of interest our own United States holds for those who can.afford to see them would take many news- paper pages. Suffice to say that there is not another nation under the sun that possesses such-varied and inter- esting lot of attractions. And to the motor car must go the credit for bring- ing the realization of this fact home to our people. Every State in the Union holds something of intefest for the people of the other States—for the people of the world, let it be known— and as old roads are improved and new ones built the people of Maine are going a-motoring over them -to visit the people of California; Oregon folks will visit in the Carolinas; Min- nesota will drop in to say “howdy"” to Florida. And these calls will be repaid. During this social intercourse be- tween the people of the East and the people of the West the commercial in- terests of the intervening States will benefit to a degree never enjoyed while travel was confined to the roads of steel. The farsighted folks of the Commonwealths lying between the Eastern and Western seaboards real- ize this, and they are working fever- ishly to make the routes through their respective communities attractive to the tourist. The town, county or State that isn’t making preparations to receive high- way travelers will soon find {tself in the present pitiable plight of the town that didn’t make an effort to get on the railroad line 50 years ago.

Those persons living in America are ltving in a country without equal in many respects, but particularly so when _considered as a motoring place, and they should grasp every opportu nity presented to them to see the coun- try from a motor car. Automobile touring through the country is not only a liberal education, but it is a health-giving recreation.

Quantity production by motor car manufacturers in this country has sun to numbers of cars, but in Enghand it 18 going in the direction of multi- plylng cylinders. The most American manufacturers have achieved so far was to fit an even dozen to one car. This limit has been sprpassed by & factory near Birmingham. Engiand, which is com- pleting an automobile that will have an even two dozen cylinders. This monster power plant is rated offictally at 1,000 horsepower, roxi- mately 50 times as powerful the ordinary passenger automobile. Its estimated speed is in excess of 200 miles an hour. So unwieldy is the glgantic machine that it will steer only a straight course. Gasoline will be fed from eight car- buretors. Ignition is to be supplied by 12 magnetos. There will be two spark plugs for each cylinder.
