History Lesson Number Two

Some time ago I printed an image of the First Gasoline Traction Engine. Well before 1892, which is the year of record for that accomplishment, a method of turning over the rich prairie soil was needed so a gentleman named "John Deere" fabricated a steel moldboard plow. This event happened in Grand Detour, Illinois and a marker has been erected there.
Now you know that the year 1837 was a turning point in American agriculture.
