This scene took place in the early 1900s on the Riviere Tomasine in Quebec . The river drive left logs hung up on banks and gravel bars.  Rearing crews sacked the shores and shallows, re-floating stranded logs.  The white-water man shown here is using a Peavey to pry, or cant, a wedged log into the main current of the river.  The Peavey, fashioned by Joseph Peavey in 1858, revolutionized river log drives.
