A man on the platform back of the binder pitched the bundles to the stacker who built them into conventional cone-shaped stacks, where they remained until the last job was threshed. Then the Humphrey crew drove from job to job with a team of the largest I've ever seen and baled the long rye straw bundles into long square bales. The horses operated a sweep winch which compressed the straw in a baler by a cable from the winch to the baler. This process today would seem unbearably slow. The baled straw was shipped to harness factories where it was cut into 11 inch lengths and used to stuff horse collars. I have seen this done and still have two straw-stuffed horse collars.
Some jobs were threshed right from the shocks but others stacked the grain bundles - then there was little danger of loss by excessive rain. The engineer in the picture is my Uncle - Ernest Williams.
The stacks of grain were built in groups of four and the machine pulled in between, threshed, and moved to next group. Mr. Watson is now 78 and going strong lives in Corunna, Ontario, Canada.
