This paper deals with a study which had two major purposes: (1) to determine the effectiveness of certain preplanting treatments in permitting pines to come through hardwood competition, and (2) to compare survival and growth rate of planted loblolly and slash pine under the various treatments tested.

The Hitchiti Forest Research Center was established in 1946 by the Forest Service, USDA, to find ways and means of producing more wood in the depleted forests of lower Piedmont Georgia, Alabama, and South Carolina. Sixty percent of the 18-1/2 million-acre territory is in forest. The forest consists principally of even-aged stands of loblolly pine on the uplands and a mixture of oaks, hickories, yellow-poplar, and other hardwoods on the moist sites.

This paper discusses four classes of lumber timming machines applicable to the planning mill. The classification is made according to function as follows: Irregularity or defect removal to increase the value of residual portion. Double end trimming to a length standard acceptable by the trade, trimming to specified length of the higher grades of stock after it has been tied into bundles, and end matching to random length stock to permit fuller utilization of the shorter lengths.

THE FORESTER'S JOB, if he is concerned with producing tree crops, is to grow the large t volume of the most valuable species. Thus, in practically every timber r egion in the United States, foresters encounter the problem of limiting the growth of less valued species which inhibit high production of the preferred species. Often these less desired species are utterly worthless and are referred to simply as "brush. " F or example, laurel and rhododendron slicks cover vast areas in the Southern Appalachians that could produce valued tree crops. Yaupon in East Texas, hazel brush and alder in...

Forest fire control in the Northeast is a bigger and more responsible job than most people realize. State , Federal, and other agencies cur­ rently spend some 6 millions of dollars in prevention efforts and in sup­pressing the 15 or 16 thousand fires that burn each year. There is good reason, therefore, to deve lop better and more uniform method s of damage appraisal so that the total fire bill--cost plus loss--can be determined with greater accuracy. It is only thus that the value of present and planned protection can b estimated.

In a study in north central Mississippi, the litter and surface soil under even-aged eastern redcedar, loblolly pine, and adjacent herbaceous cover varied chemically, physically, and biologically. There are good grounds for belief that soil rehabilitation proceeds faster under redcedar than under herbaceous or loblolly pine cover.

Forest plantations in north central Mississippi and western Tennessee can produce merchantable timber on much land which erosion has made useless for other crops Forest plantings usually can decrease, stop, or forestall erosion economically. This paper describes the most important sites in the area, predicts what may be expected if they are planted to trees, and suggests the tree species and planting procedures most likely to succeed. The opinions and conclusions are based on field observations during the past three years. The majority of these observations were made during detailed study...

Do bottomland hardwood forests respond to improvement cuts? Do growth rate and stand quality increase enough to make up for the extra effort and, sometimes, outright expense of improvement cutting? Ten years of growth on some plots on the Delta Experimental Forest near Stoneville, Mississippi, indicates that the answer to both questions is "yes".

This article reports early changes in growth rate brought about by partial cutting in two bottomland hardwood stands. Better information will be forthcoming as re-measurements are made over longer periods. Indications are, however, that the acceleration of growth caused by release is large enough to be a vital factor in planning future cuts.
