...than 100 H. P.-92 H. P. was the conservative figure mentioned in advertising when the car was announced more than one year ago.

The engine hissed, the piston began to churn; the President waved goodbye to Gabriel (a town near White Pine Camp), Mrs. Coolidge filmed the natives with her cinema machine...
...advantage of Diesel motors over gasoline motors in automobiles would be their simplicity of structure and absence of vibration. Instead of a carburetor and valves, a Diesel* motor has a small spray to inject fuel into the cylinder at the moment when the piston has risen and greatly compressed the air in the chamber. Compression makes the air so hot that ignition is automatic and the explosion gradual and more powerful than the complex explosion obtained with a spark plug. No generator or distributor is needed by a Diesel; no pressure oiling system. The Diesel's fuel is crude...

His knee-bolt pumped like an engine piston; his straight arm fell like a Big-Wood tree. Last week, after a summer on ice, he twice manifested himself before his heirophants. First he prepared to take the field against Nebraska, his ancient enemy; secondly he addressed a message to his personal public in the October issue of the American Boy. The message?a three page article on football?was signed with his name...
