Plate IV 
Fig. 1.— Face from narrow-chipped area at the end of the first year of turpentining (1916). About one 
foot in height of chipping surface used. 
Fig. 2.— The hack to the left of the picture is a "00." This type was used in the narrow and double 
chipping at Columbia, Miss. The broad "billed" hack to the right is a "No. 2," the type used in the 
standard chipping at Columbia, Miss. 
Fig. 3. — Face from the double-chipped area at the end of the first year of turpentining (1916). About 
two feet in height or twice as much chipping surface was used here as in the case of the narrow chipping. 
(Compare figure 1.) 
Fig. 4.— Low face on narrow chipping at end. of second year of tmpentining (November, 1917). Note 
paddle over cup to keep out trash. 
Fig. 5.— A dry face. A considerable number of trees on the double-chipped tract at Columbia, Miss., 
showed dry faces during the second year of the operation, indicating reduced vitality of trees. 
Fig. 6.— Relatively high face on the double-chipped area at the end of the second year of turpentining 
(same height as standard chipping). Note chip-catcher attached to puller. Somewhat higher yields 
may be obtained by this method in short operations.
