This very old threshing machine, built long ago in Stratford, Ontario, is a marvel of early 20th century farm technology. I posted this photo as a fairly large file so that you will be able to click on it and see the finer details of the weathered wood, paint and decoration. What I really loved was the leather belts that drove the internal gears. Threshing removes the grain from the wheat stalks. The stalks wind up as golden straw to become winter bedding for cattle and then mixed with manure for fertilizing the fields in the spring.
I much prefer the smell of straw/manure to the liquid manure so often spread in modern farm practices today. The first has an almost sweet odour while the second seriously makes me gag.
