In sawlog growing stock, both softwood and hardwood declinded 2 percent between the Forest surveys. The 1949 saw-timber volumes are 11.3 and 6.9 billion board feet, respectively.

Ecologicall y the forests of pure or nearly pure southern pine that r ange so extensively along the central and southern Atlantic coastal r egion are sub-climax types . Thus the natural tendency is for our pine fo r ests to be r eplaced eventually by the climax hardwood species : maple, beech, oaks , and hickories .

During the winter of 1948 and again in 1949, some 3,200 bald-cypress seedlings were planted in a cut-over cypress and tupelo gum swamp near Choctaw, Lafourche Parish, Louisiana.

Pulpwood production in the seven states of Southern Forest survey territory reached another all-time high in the 1948. Total production was 5,025,900 cords, an increase of 14 percent over 1947. Each of the seven states showed an increase (table 1).

Climate in the generally used sense is determined by physical conditions over which man has no control, namely: latitude, prevailing wind, topography, and nearness to the ocean or continental interior. Locally, certain elements of climate, such as temperature, wind, evaporation, and rainfall, are modified by altitude, topography, direction of exposure, bodies of water, and vegetation. The extent of these modifications defines and characterizes the local climate.

This publication summarizes the data on forest area, timber volume, and timber growth collected by the Southern Forest Survey in the Ozark region of Arkansas, the 24 counties in the mountainous northwest portion of the Stats (figure 1). The survey, made between April 1947 and April 1948, was the first of its kind in this section of the State. The remainder of Arkansas, covered by the Southern Forest survey in 1935 and 1936, will be resurveyed in 1949.

The southern pulp and paper industry is again on the march. Practically as soon as the war was over several plants started expansion programs, and construction was started on a number of mills. Investigations and surveys now under way also indicate that additional new pulp and paper mills can be expected to locate in the South in the near Future. This is not news to you members of the industry, but it does point up the need for a review of the South's timber supply in order to see if annual yields of wood are large enough to meet present requirements and at the same time allow for some new...

In the conventional cutterhead arrangement the presure on the lumber passing through the planer is exerted downard-forcing the stock against the lower bed line first.
