In October, 1905, nineteen permanent sample plots were established in the white pine type near Keene, New Hampshire, by the United States Forest Service in cooperation with the Faulkner and Colony Manufacturing Company on lands owned by the latter. The plots were remeasured in 1909 and again in 1915 by representatives of the United States Forest Service. After the 1915 measurement the plots were turned over to the Yale School of Forestry. In September, 1920, the plots were remeasured for the third time, three additional plots were established and six of the original plots were discontinued. Fifteen years have elapsed since the beginning of the experiments. While the experiments are only partly completed, information of value in reference to the management of white pine has been acquired. The purpose of this publication is to make the information available for foresters and landowners engaged in managing white pine lands.
