Apparently it wasn't manly to smile for the camera. Gotta love the dog though.
The use of Big Wheels for logging was first invented in Michigan in 1870 by Cyrus Overpack. Their problem at the time was that the logging season was then limited to winter months when snow and ice made it easy to skid logs from forest to mill or railhead. During late spring and summer months the industry basically had to shut down. With the advent of the big wheel, they found a way keep logging year around.
By the late 1800s using Big Wheels here in the northwest also became common. These wheels were 10 feet high with the big end of the logs fastened under the tongue. When oxen or horses pulled, the end of the logs would raise, permitting the other end to then be more easily dragged along.
To my surprise, even as technology advanced, the use of Big Wheels continued into the 1930s. This says a lot about the virtues of simplicity.
