Lesson62 After the fire
Firemen had been fighting the forest fire for nearly three weeks before they could get it under control. A short time before, great trees had covered the countryside for miles around. Now, smoke still rose up from the warm ground over the desolate hills. Winter was coming on and the hills threatened the surrounding villages with destruction, for heavy rain would not only wash away the soil but would cause serious floods as well. When the fire had at last been put out, the forest authorities ordered several tons of a special type of grassseed which would grow quickly. The seed was sprayed over the ground in huge quantities by aero planes. The planes had been planting seed for nearly a month when it began to rain. By then, however, in many places the grass had already taken root. In place of the great trees which had been growing there for centuries, patches of green had begun to appear in the blackened soil.
