SYNTHETIC RUBBER FOHTIS FORESEN Plant Biologist Will Be Strong- est Ally of Natural Product, Says Chemist. Snythetic rubber and the natural product some day are going to meet and fight it out for supremacy. This clash will bring an unusually bitter industrial war. This forecast is made by L. E. Weber of Boston in a summary of the rubber situation made public by the American Chemical Society. Synthetic rubber is yet far off, and when it does come it will be forced tg‘ fight, declares Mr. Weber, and the chief ally of its adversary will be the plant biologist, described as a_future foe of untold power.

BALTIMORE, May 22.—The final section of the $1,000,000 Crain high- way, which can be built within the present appropriation, will be con- structed this = Summer. The new section, consisting of 21 miles of concrete near Priest bridge, will exhaust the $1,000,000 which was appropriated ove period of four years for construction of the southern Maryland road. Mr. Mackall said that a new appro- priation of $250,000 will be necessary the complete a gap which will remain after this Summer. Gov. Ritchie has | proraised to recommend such an ap- propriation at the next legislative ses- sion, according to Mr. Mackall. The gap which will require a new appropriation for completion will be about § miles between Halls station and Upper Marboro, in Prince Georges BRITISH TAXES HEAVY. Nearly $58,000,000 Taken in From Automobile Levies. Nearly $58,000,000 in motor and other vehicle taxes was collected in Great Britain from December 1, 1925, to February 28, 1926, a consular re- port to the Department of Commerce reveals, The total number of motor vehicles, excluding street cars and trade ve- hicles, in respect to which licenses were current February 28, was 1,177.- 000. These included 488,000 cars taxed on horse-power, 339,000 cycles and 232,000 commercial vehicles. VALVE SEATING TEST. Marking Each With Pencil and Noting Breaks Suggested. Here ig a simple way to tell when a valve is seating properly following grinding. Mark the valve seat under inspection with a pencil. Then grind the valve a few times and note the lines. If each of them is broken, the valve is then seating at all points. It is not necessary that the lines be en- tirely removed, simply that they be 7 GUARDING OF SPRINGS VARIES WITH AUTOS Care Should Be Used to Learn How Each Type Works Before Plan- ning Protection. s are turning w-minded ob Wise automobile ow a deaf ear to those servers who argue are useless.

Indigo Not Organized. “The production of indigo was not an organized industry. It was entirely in the hands of the uneducated native, whose methods of production were not only inefficient but ruthless, and| whose business methods were grossly unethical. The native planters were totally unprepared, in fact were in- capable of preparing themselves for the economic conflict which was facing them. “Notwithstanding, it required the expenditure of huge sums, both in the of technical vestigation and subsidy, before the synthesist was able to proclaim himself the victor. “How ‘different is the situation in the rubher plantation industry! points’ with |~ ___(Continued from Fifth Page.) will go up in the alr at the driver's will and when the wildest dreams will come true. They base their predictions on the philosopher Herbert Spencer. who said: **The human mind can conceive of nothing that is not possible of ac- complishment.” If it wasn't possible, one could not even think of it. Long ago some one thought of a vehicle that would run on its own power. He was thinking of the automobile. Even that was possible of accomplishment. Fact Worth Remembering. Where brakes are subject to vari- ation in efficiency as a result of ex- posure to weather conditions it is just mportant to_know when the, only is it organized, but it is keenly conscious of the benefits and potential- itles of scientific research; and the door of research i open just as wide to the plant biologist as to the chem- ical synthesist.

Drivers { pay particular attention to the matter | of ‘brake inefficiency, but often forget to consider over efficiency. That is yWhy it occasfonally happens that a ldriver slams on the brakes only to find them working so well that a skid is started. This is likely to occur when the brakes are a bit damp and the streets are wet. Did You Know That— A poppet valve engine reduces its own power, not only in compressing ings but in lifting its ex- s against the pressure of expanding gases? The biggest advantage in the use of steel or disc wheels is in protecting the brakes from water and dirt? An oll pressure gauge is made to read higher than it ever reads for greatest speeds merely to take care of the abnormally high recording when the engine and its oil are cold? Safety on the Side. Strong bumpers, front and rear, are not the only protective features this vear. More and more there is a tendency toward side protection, a consideration that is becoming more The Foyous Natisfattion That Only (adillac (an Give and more important as traffic con- ditfons grow more complicated.
