What effects do grazing cattle have on the hardwood forests of the Mississippi Delta? What is the value of the forage to the cattle? To answer such questions, grazing studies were conducted in 1957 on the Delta Experimental Forest, near Stoneville.

Tests at Stoneville. Miss., indicate that refrigeration can keep cottonwood seed viable for several weeks.

During recent months members of the Tropical Forest Research Center staff have travelled to many of the countries of the Caribbean area. The purposes of these trips have been to see trees, forests, and silvicultural and utilization practices that might be useful in Puerto Rico, to collect data on forest plantations for the Latin American Forestry Commission of FAO, and to obtain infonnation of value to the forestry training program of the Center, set up to serve this area through the cooperation of the International Cooperation Administration. Forest management work and plantations were...

One of the factors preventing more widespread planting of the true pines (Pinus spp.) in the tropics is the present necessity of using potted stock instead of barerooted seedlings, such as are used throughout the temperate regions. Potted seedlings require more space, more equipment, more labor, and more money, both to produce in the nursery and to plant in the field.

The pulp and paper industry greatly increased its capabilities. Two new multi-million dollar mills were established at Pine Bluff, and existing plants at Camden and Crossett were enlarged (fig. 1). In response to industrial expansion, the total output of pulpwood increased more than twofold--from 604,000 cords in 1950 to 1,524,000 cords in 1959. Additional expansion of the industry within the State and in peripheral areas promises to boost pulpwood production-both pine and hardwood-to new records in 1960's

Time-temperature relations were measured during the course of a preliminary investigation of the thermal characteristics of forest fires. Observations on 5 head fires and 5 backfires in 8-year-old gallberry-palmetto roughs on the Alapaha Experimental Range near Tifton, Georgia, are the basis for this report.

This booklet has been prepared to assist photo interpreters in recognizing broad forest types on aerial photographs of the South, and to illustrate primary differences between panchromatic and infrared photography from the standpoint of timber type-mapping.

To find out what kinds of individuals are particularly interested in forestry and how they use their forest land, 100 owners were interviewed (fig. 1) and their woodlands examined in each of two study areas, one in the North Carolina Piedmont and the other in the Georgia Coastal Plain. Total acreage of the two areas is about the same. And although total acreage in forest is about the same too, forests are of greater economic importance in Georgia than in North Carolina.

The maps in this report describe the relative concentration as well as the approximate range of 11 softwoods in 12 southern states--extending from the Atlantic Coast westward to about the 96th meridian in Oklahoma and Texas. The data upon which the maps are based were gathered during 1947-57 by the Forest Surveys of the Southern and Southeastern Forest Experiment Stations of the Forest Service, U.S. Department of Agriculture.

For maximum efficiency a headrig for converting bark-free bolts into cants must (1) have a fast cycle time, (2) require minimum handling of bolts and refuse, and (3) convert the volume represented by slabs and kerf into a salable byproduct.
