PICTURESQUE JEFFREY PINE, THE VICTOR IN COUNTLESS MOUNTAIN STORMS, Yosemite National Park. This gnarled Jeffrey pine, on the summit of Sentinel Dome at the 8,117-foot elevation, not only has withstood heavy snows and icy winds for many, many years, but it also has human enemies. Despite signs asking people not to climb on it, here parents permit their children to do just that. On the lower part of the trunk, at the extreme left, can be seen a step cut by some vandal; and not many years ago another damaged it by driving a large spike into its trunk. Unhappily it would be impracticable to keep a ranger on guard here all the time, even with much larger appropriations for protection.
