 cylinder motors which developed little power comparatively? Kinner had a dream. He built one of his own. It had been bought by the man who financed one of the first planes built, in the west, by Donald Douglas, designer of the Round the World Cruisers. Mr. Davis and Mr. Douglas at the time were planning a trans-continental non-stop hop, using a big Liberty engine. But the P.2 flown by Macready and Kelly to San Diego, in the first coast to coast flight, got across first. I bought the Kinner engine from Davis, who was not ready to use it just then. It was the first engine that Kinner turned out.

Of course it was full of "bugs"-no degree of mechanical perfection is ever attained without successive stages of development. Each improvement is a result of many practical working tests. Human intelligence seems to grasp ideas in steps and must work through complicated details to efficient simplicity. The first automobiles had whip holders on the dash, remember.
