7/21 The most effectual way to fight light surface fires is to throw sand or earth on the flames. Where the fire has not made much headway, the flames can sometimes be beaten out with green branches, wet gunny sacks or blankets. The leaves and debris may be raked away in a path so as to impede their advance. Fires in these forests destroy the seedlings and saplings, but do not usually kill the mature trees. They also burn the top soil and reduce the water-absorbing powers of the forest floor. |
