Аннотация: The purpose of the present study is to test critically the covariation of tree growth and rainfall-tree growth as measured by the thicknesses of growth layers on increment cores. There are two general conclusions. First, the evidence indicates rather clearly that variations in tree frowth follow variations of March-July rainfall from year to year very nearly 100% at the immediate site of the trees. Second, the evidence strongly suggests that changes of internal agreement among the trees and changes of average variation , average departure, and average departure from mean variation can be used as a method to reveal changes in rainfall through the years where amount of rainfall, and hence derived soil moisture, approximately equels that present at the location of the dominant members of the Holman Pass collection
