9/21 Fires also run along the tops of the coniferous trees high above the ground. These are called "crown-fires" and are very difficult to control. If the fire can be turned so that it will run into the wind, it can be put out more easily. Fires that have the wind back of them and plenty of dry fuel ahead, speed on their way of destruction at a velocity of 5 to 10 miles an hour, or more. They usually destroy everything in their course that will burn, and waste great amounts of valuable timber. |
