 LIFE IF THE
 MOTOR TRUCK

Ever since motor trucks were first built in 1904, the overload evil has Leen the most serious thing that truck manufacturers have had to contend with. The very first truck was frequently overloaded and per haps the last one will be, but in the meantime thousands of motor trucks are passing into the discard each year. Overlooking, overspeeding and Carelessness in upkeep are daily shortening the life of all types Of tuIcks and the manufacturers only hope for the lessening of these evils is that motor truck owners and drivers will profit by their costly experiences and effectually reduce these practices to the very minimum if not eliminate them entirely, ac- cording to Manager C. H. Howard of the local Goodrich branch.
 Motor truck manufacturers are not dependent, as many may assume, upon the discarding of worn out trucks to enable them to sell new ones. Taere is no manufacturer who does not point with pride to the old est trucks of his make that are in service today. The longer the ser vice of his truck, the better the maker is pleased, for then the own CT is not only satisfied but this con dition leads to greater sales. There has never been an production of motor trucks. In fact there has been a shortage each year and this shortage applies to all sizes and types
 Truck builders have tried every conceivable means of eliminating the overload evil The most universal action in this direction has been an absolute cancellation of the makers guarantee where the load capacity Is not strictly adhered to. Many users make the mistake of thinking that the manufacturers of their trucks are unable to determine that they have been overloaded. It is inn possible to conceal this fact, for, as trucks are now being built, there is nothing else that will produce the eff fleets that overlooking does.
 When the truck builders had ap parentlv exhausted every resource for combating overlooking, Overspeeding md negligence in the general up- keep the B. F. Goodrich company at tackled the problems from an entirely different angle. in an illustrated ar 'icle published in an introduction in the fifth volume of Motor Trucks of America which is issued each year hy the Goodrich Truck tire depart ment.
 The title of this article is Length ening the Life of the Motor Truck" 9nd the story tells all that it's sub feet implies. In part it reads, It is of little use to tell the truck operator that he must not over bad. must not overspeed. etc. He gets that every week of the month. u is not enough to say overlooking is bad He must be told why it is bad and given actual reasons. Al ways the human mind asks why and if the reason is insufficient it is not satisfied But the reasons for overlooking are founded upon mathe- matics. an exact science"
 The truck engineer knows the linn it's of endurance as he constructs the lines and curves of his blue prints with the aid of his slide rule his calculus and his technical education, but the driver or the superintendent who is responsible for the operation of a fleet of costly trucks merely knows that overlooking and over speeding are bad. It is not enough.
 The Goodrich company has gone into the offices of the best truck and automobile engineers in the country
