When I was 12, I spent a summer in the woods logging with my Uncle Rollo and Dave Nielsen. This saw is a Mall but is similiar to what we used. Rollo had a 5 hp McCullough with bike handle grips and a 48 inch bar. The bar could rotated 90 degrees to fall trees or to buck them up to saw logs 16 feet or shorter. Dave had a 3 1/2 hp with a 2 foot bar. Rollo did the falling and Dave bucked the logs to length. Both would limb the trees. We were cutting in the La Sal mountains in southeastern Utah. We started in Ponderosa pine and latter went up higher and cut spruce. My job was to climb on top of down tree and mark the tree to lengths to be bucked up. I would limb enough so I could walk down the log and mark the lengths,using a quakie, 10 feet long for a measuring stick starting with 16, feet then 14, 12, 10 or 8 foot lengths. The last cut would generally be shorter than the earlier 16 footers. Would go out to 8 inch in diameter. Also It was my job to mix the saw gas each evening for the following day. We lived in a one room cabin near where we worked. Later Dave's wife, Donna and their 2 kids, came to stay with us. Donna did the cooking so we were able to spend more time cutting. There were 6 of us living in the one room cabin. Cabin was built on skids so it could be pulled to other locations near the work.
