"[An] excellent study of the bristlecone pine (Pinus aristata Engelm.) from the White Mountains of California [...] Many aspects of tree growth and a multitude of growth factors are considered in great detail [...] An intensive study was made of six small, rather young trees using dendrographs, dendrometers, soil-moisture units, weather-recording instruments, and cambial sampling for the years 1962, 1963, and 1964 [...] The author has done an enormous amount of work in statistics, botany, and ecology."
