“These trees are not as large in diameter as the California Redwoods, but there are a great many more of them,” replied Cecil. “We have mile after mile of trees as large and larger than these in Oregon and Washington. In order to protect these trees, the government has set aside certain forest preserves which are called National Forests. There are 152 National Forests in the United States. Each of these National Forests has a supervisor in charge. He has under him wardens, rangers and lookouts. These men all work to detect and suppress fires.”
