EFFECT OF' REPEATED FOREST FIRES   175

Patches, several acres in extent, containing 550 young pine from one inch to six inches in diameter, were frequently encountered, but the average is 125 white pine and 53 red pine per acre. In the area east of Eels brook there are occasional groups of pine, varying in extent from a few trees to those covering several acres, which apparently escaped the fire with only slight injury, and they are now approaching commercial value, one-half of the stands being from six inches to ten inches in diameter and averaging 70 trees to the acre. An area of similar character was found just west of Kasshabog lake, in Methuen township, and it covers about 800 acres; here the number of pine trees approaching commercial value averages 15 per acre. Scattered through this area are frequent groves, aggregating about 300 acres, which contain 30 trees from 9 inches to 15 inches in diameter per acre, and are, therefore, of commercial value.
