That Douglas fir over there is close to two hundred years old. Some of those pines close by are just as old. You can see that the lowest branches are over a hundred feet above the ground. The tops of those trees are over three hundred feet above us. An entire forest of those trees can be destroyed in a few hours through the carelessness of a man who is enjoying a vacation in the woods.”
