Unless you are a logger moving a spar tree while keeping it upright.
From the description at the photo source:
Univ. Washington Library
"What you are actually seeing is "jumping a tree." If you look at the bottom left side of the photo, you can see the log mat that it will rest on. This was done when a spar tree was not quite in the proper location for logging, usually too far away from the landing. You would rig three or four "head guys" cut the tree free from the stump then with a cable strap and a block (pulley) you would jump the tree from the stump to the mat then skid it down the mat to where you wanted it. At the time the photo was taken, probably a steam "rig-up donkey" was used for power. Each guyline would have two or three men either taking up slack around a guyline stump or rendering (feeding slack out) their guyline as it moved away from them. This was usually only a few feet (less than 50). the trick was to tighten the guylines, and render the guylines at the same time to keep the tree vertical. I have helped do this once, in the late 60's, probably around 1969, I can't quite remember. It was done for a truck logging show. The tree was at the edge of a landing and it needed to be more to the center, so logs could be landed safely. I only write this correction because so few loggers are left now that ever worked under a wooden tree. As a side note, I helped dress (hang the rigging) and un-dress the last wooden tree at Snoqualamie. It was a raised tree, (trucked in) and I believe that was in either winter of 1973 or spring of 1974. Afterwards, Weyerhaeuser Snoqualamie was purely a steel spar operation to my knowledge.
