Don Carlos Ellis, in charge of the exhibit, has announced an-nounced that arrangements have been completed whereby the district foresters throughout the country will report to him promptly all forest fires occurring in their districts and the amount or damage they cause. As the reports are received they will be immediately posted on a map. by means of different colored pins, white pins indicating fires below one-quarter acre in extent, black for fires less. than ten acres, and red for fires more than ten acres. This arrangement means an extension of a similar exhibit confined to the national forests of California which was installed at the beginning of the fire season. This proved so popular popu-lar that the larger plan, to include the entire country, was adopted, with the special purpose of interesting visitors from other states. The new map has already been installed. in-stalled. The reports which it gives are cumulative. They show that up to August 1, 1912, fires had been reported from the national forests in the six western districts, of which 71 6 were caught and extinguished before they had burned one-quarter of an acre, 316 before be-fore ten acres had burned and only 180 which burned more than that acreage. |
