SpiraJ - shaped Gutters better With Bark Chipping Spiral shaped metal gutters were designed for bark chipping. These gutters fit the tree snugly. They can be used on wide faces where high gum yields are wanted for a few years; for example, on trees to be cut selectively.

Hybrid Progeny Now Three Years Old Seedlings in the progeny test of crosses between slash pines of different gum yield capacity are now three years old. The average height of seedlings is feet, with 95 • 5 percent survival. In addition to this plantation, there are on hand about 1,200 seed from controlled pol- linations and these will be used for additional plantings. Tests Continue On Types and Frequencies of Chipping Many studies with different types of chipping, face widths, frequencies of chipping and treating.
