Abstract

While engaged during the late summer of 1924 in the gathering of data for yield tables in stands of sweet gum (Liquidambar stryaciflua L.) and river birch (Betula nigra L.), in one of the southern counties of Maryland, the attention of the writer was attracted to the striking occurrence of pure stands of these species on adjacent tracts of land, with no apparent cause for the sharp line of demarcation between the two types of forest. Suspecting that some difference in soil structure or soil moisture, or possibly both, might offer an explanation for this rather strange association, more detailed observations were made late in the fall of 1924, and the results of these observations are embodied in this paper.
