THE NAVAL STORES INDUSTRY.

intended to be accurate for any particular locality, but rather to 

 represent as correctly as possible the conditions generally obtaining 

 over the territory, the unit of consideration seldom being- less than a 

 county. The high price of naval stores in 1911 produced an unpre- 

 cedented invasion of the " round" timber. It has been estimated 

 that 75 per cent of the "round" timber held by turpentine operators 

 was tapped in 1912. 



YIELDS PER CROP IN VARIOUS STATES. 



Table 16 shows the yield per crop in six States in the turpentine 

 belt and the percentage of gum secured by boxing and cupping. It is 

 noticeable that the States in which the yield per crop was largest 

 also made the largest use of improved methods. The timber used in 

 turpentine operations in Louisiana and Texas is, however, generally 

 of larger size than in the other States mentioned, so that a somewhat 

 larger yield per crop under the same conditions would be expected, 

 although not such a difference as shown in Table 16.

Table 1 7 shows the new crops started by the box and cup methods 

 in 1909, 1908, and 1907. The figures indicate that the cup method 

 is steadily gaining ground; they also show that North Carolina and 

 South Carolina at present play very little part in the production of 

 naval stores.
