This bulletin is a study in forest mensuration which has arisen out of investigations into the timber content of British woodlands. It deals primarily with the relationship that exists between the volume of a tree and its sectional area at breast height; a relationship here called, for convenience, the volume-basal area line. Studies of this relationship have made possible the production of general volume tables and general tariff tables, which facilitate the rapid and accurate estimation of the timber content of certain types of plantations, and are therefore of considerable practical importance to foresters working in the field.
