first stroke draws in the gas, the second compresses it, the third is
the explosion or power stroke, while the fourth stroke exhausts the
waste gas. The little model worked well enough; it had a one-inch bore
and a three-inch stroke, operated with gasoline, and while it did not
develop much power, it was slightly lighter in proportion than the
engines being offered commercially. I gave it away later to a young man
who wanted it for something or other and whose name I have forgotten; it
was eventually destroyed. That was the beginning of the work with the
internal combustion engine.

I was then on the farm to which I had returned, more because I wanted to
experiment than because I wanted to farm, and, now being an all-around
machinist, I had a first-class workshop to replace the toy shop of
earlier days. My father offered me forty acres of timber land, provided
I gave up being a machinist. I agreed in a provisional way, for cutting
the timber gave me a chance to get married. I fitted out a sawmill and a
portable engine and started to cut out and saw up the timber on the
tract. Some of the first of that lumber went into a cottage on my new
farm and in it we began our married life. It was not a big
house--thirty-one feet square and only a story and a half high--but it
was a comfortable place. I added to it my workshop, and when I was not
cutting timber I was working on the gas engines--learning what they were
and how they acted. I read everything I could find, but the greatest
knowledge came from the work. A gas engine is a mysterious sort of
thing--it will not always go the way it should. You can imagine how
those first engines acted!

It was in 1890 that I began on a double-cylinder engine. It was quite
impractical to consider the single cylinder for transportation
purposes--the fly-wheel had to be entirely too heavy. Between making the
