Excerpt from Common Plants of Longleaf Pine-Bluestem Range Numbered studs were machined $48 On a planer equipped with a crook reducer, then graded by spie rules and tallied. Within 10 to 15 days of planing, the weight, twist, crook, and bow of each stud were recorded. All were then carefully stacked with sticks in a building controlled at 72 F. And 50 percent rh. After 6 weeks on sticks, the lumber reached approximate equilibrium moisture content (emg), and the weight, crook, twist, and bow were again recorded. Ovendry weights and specific gravity were calculated from determinations made on 2-inch cross-sectional slices from ends of all studs.

Crops of bobwhite quail (Colinus virginianus) collected in 11 years in the longleaf-slash pine forest type were examined for food content. Seeds of woody plants made up 45% or more of the volume of food found in crops in 9 of the 11 winters. Seeds of pines, drupes of red bay, and acorns from various oaks were large-volume food items in certain years. As a group, seeds produced by legumes were the next largest in volume, varying from 2 to 48% in the 11 winters. Seeds of partridge peas, common lespedeza, bush clovers, milkpeas, and tick-clovers were important species. Volumes of seeds of grass, spurge, and sedge families were usually less than 12% for each group, and volumes of green leaves and animal matter less than 5% each. Panic and paspalums were principal grass species. Availability of seeds influenced consumption by forest-dwelling quail. In habitat management for quail, a variety of trees and shrubs should be maintained in the forest type to better insure a dependable food base, season to season and year to year. Similarly, desirable herbaceous food plants should be encouraged by fire and mechanical means.
