CONSERVATION IF
 FUEL FORCES NEW
 ME BOTANICAL IDEA

The conservation of fuel of all kinds has proved to be one of the. most mo- mentous problems of recent years. or course everyone is acquainted with the stress laid upon the saving of coal dur ing wartime and the period succeeding, and the various special and extraordi- nary measures to that end put into ef- feet by national and municipal author ities. Private concerns adopted every practical fueI-saving method and even householders employed means of con- serving their meager stores of fuel that were little short of heroic
 Since the. passing of the pressing emergency Of the war months, how ever not so much is said of the urg- ency for being judicious in the use of fuel, and the fact is that very little is known of the far reaching results of the former necessity for getting the utmost energy out of every particle of fuel available for use.
 It iS a very noteworthy fact that scarcity, and the resulting higher cost of fuel turned loose the trained talent of the whole nation on this problem and some of the results are astounding in their effectiveness, but in spite of this, are but little known. and even when made public, have excited little comment and are accepted as mat ter of course.
 Of all fuels, the greatest need for more efficient usage was felt in con- nection with the consumption of gas oline. It is accepted that the larger part of gasoline production is utilized in producing motive power. The work of one concern whose product is de- pendent on gas power, the Liberty Mo- tor Car company, is therefore slgnIf1- cant of the importance attached to this question and the ingenuity displayed in multiplying the effectiveness of gas fuel.
 The car which this company pro- duced during 1918 and 1919 was one with a horsepower rating of forty-five. It developed a speed of about fifty miles an hour. The touring car, which seated five passengers, had road weight of 2750 pounds, and covered an average of about fourteen miles to the gallon of gas, a common mileage for car of it's size, weight and horsepower. During the early part of 1919 the Liberty engineers started a branch of the engineering department to special izing on the better utilization of fuel. They conducted experiment after ex- pertinent and test after test on the re- suits from different bore and stroke measurements, various type manifoids, and a number of interesting methods of preheating the fuel before 1t entered the combustion chambers. The man who had charge of this work was an engineer who had already attained na tionaI recognition through devising the most successful gas saving device used on motor cars up to that time.
 The success of later ingenious engi- neering developments is better illus trated by. their results than by lengthy description of the various mechanical! advancements embodied in this car.
 The new series Liberty is. first of all. slightly larger, the new car weighing approximately 2s50 pounds. The wheelbase is two inches longer and the body length has been increased. The
 motor itself is just twenty pounds heavier than the motor formerly used Tn addition to this, a marked increase
 in speed has been attained. the new
 car being able to develop a pace of sixty miles an hour. And of still
