In keeping with its wide distribution it encounters a very wide range of practically all of the climatic condi- tions, exceeding in a number of cases the extremes for the Deciduous Forest region, in which it finds its greatest development. The nar- rowest amplitudes for Quercus alba are those of the number of days in the longest normal dry period, the normal mean relative humidity of the frostless season, and the moisture ratios. The first and last of these conditions appear to be responsible for the western limit of distribu- tion. This edge is roughly paralleled bj^ the line for 25 days in the longest dry period and by the line for a value of for the moisture
