The muffler deserves careful consideration every once in a while if the operator cares for efficiency and economical operation. This exhaust silencer has a great; number of very small openings on the inside of the chamber which become clogged with soot and carbon from the cylinders. The deposit collects very rapidly, especially when the grade of the. oil is poor or too much oil is used. When these small openings become clogged the exhaust gas cannot escape readily and naturally the cylinder of the engine is not clean at the exhaust stroke. Result: It. is impossible to bring in a full cylinder of new gas on the next intake stroke. There is not a full charge to explode and this means a loss of power to the engine. Prolong the life of the car by studying the oil needs of the engine.

Croy, financial editor of the Arkon, Ohio, Beacon' Journal. “Possibility of a general -upw; revision in practically all lines is being discussed in rubber circles and an important announcement concerning the new price lists may be forthcoming before Xov. 1.” Pres. O’Xeil said recently that tiro prices arc the lowest they eve have been, being based on low contracts for cheap cotton and, principally, on Hie very low average cost of rubber. ' O’Xeil pointed out that the consumption of crude rubber is now catching up to iis production at capacity and predicted that within a year tire prices would he higher because of higher crude prices.. “It is expected that prices c crude rubber wifll advance as soon as consumer buying begins,” the Akron financial editor says. “Cotton has been advancing steadily and the crop in some states may fall considerably short of the government's latest estimates due to rains in some sections and droughts in others.
