This study was begun in the summer of 1965. During that time, six areas that were burned in 1960, 1954, 1942, 1910, approximately 100 and 300 years ago were selected for intensive study. In these areas I have two summers' data on hygrothermograph records; one full summer on Moeller distance thermometers at one and six inches in the soil; atometer and rainfall area. Soil moisture, litter depth, chemical and mechanical analysis data of ten composite soil samples from each area were collected. The random pairs method was used for sampling trees and the Daubemire canopy coverage method for herbs and shrubs.
