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. The planes and motors which we see today are the results of evolution. There was a preliminary design of the now famous Wright Whirlwind motor as early as 1917 and it, in turn, had grown from models of air-cooled radials begun by Mr. Lawrence in 1914. The greatest pleasure I found in my experience with Kinner’s motor was that of perhaps having a small part in its development. Its many little ailments had to be diagnosed and cured later. It smoked and spattered oil. Adjustment of a proper propeller was difficult. One of its eccentricities was an excessive vibration which tickled the soles of the feet when they rested on the rudder bar, putting a new meaning into joy ride. Such was the hilarious beginning of one of a group of motors which are being developed in the United States. The idea of returning to the east, and doing it by air, had been simmering in my mind. Maps and data were all pretty well prepared. Then the old infection, incurred in the Toronto Hospital work, returned, and I was forced to abandon the hop, to the satisfaction of my parents. My health was so precarious that, disappointed in my intention to fly, I exchanged my plane for a car and drove across the continent. Mother went with me to remind me I was too ill to fly, and together we covered more than 7000 miles before we reached Boston. I enjoyed three days in Boston before entering Massachusetts General Hospital for a short stay. After convalescing a while I set off for New York, to re-enter Columbia. The next summer was spent at Harvard and the following autumn I began to look about for a job. My sister was teaching, so I indulged in it too. Teaching and settlement work filled the following years—filled them very full, for both occupations require much of one’s life. All these other activities allowed little or no time for aviation. Inevitably certain contacts had persisted from the California days so it was no surprise to hear from Mr. Kinner. He asked me whether I knew anyone in Boston who would take the agency for his planes and motors. I dropped in on the Chamber of Commerce for information. It was evident from the facts gathered from Bernard Wiesman, secretary of the committee on aviation, that the town could struggle along for a while without the additional luxury of a new plane. The air-mail industry seemed to be as strong a dose of aviation as Boston could stand at the time, and Sumner Sewall was having to hold her nose while he spooned that in.
