If the foot is releasedsuddenly from the clutch pedal the oil within this dash-pot M flows out gradually through the by-pass 0, this causing smooth gradual engagement of the clutch. It is evident with the hardened steel roller bearingswhich are rotating about the contact ring during slip-page of the clutch that there are no parts in the clutchwhich can be worn by slippage and consequently thedriver is free to slip the clutch as much and as oftenas he pleases, thereby giving him additional traffic con-trol without in any way damaging the clutch. The pressure required to release the clutch is equal tothe tension of a spring only strong enough to hold the. The Hubbard Oil Clutch. weight of the clutch pedal. The clutch is the product ofthe Hubbard Clutch Co. BENZOL and alcohol are readily miscible. Alcohol-benzol mixtures will not freeze at low atmospherictemperatures, but unmixed commercial benzol freezes atabout 23 deg. Fahr. The lightest grades of gasoline mixwith alcohol, but with heavier grades, and with keroseneseparation occurs. Separation is prevented by additionof a mutually miscible solvent such as benzol.

Most searchershave turned to statistical tables. Here is a suggestion for another field. By Harry Tipper* I WAS in Detroit last week visiting with some of thepeople who are at the center of the automotivemanufacturing, attempting to discover what theconditions were f
