about one-third in 1914. The import value per pound decreased 

 from slightly more than $1 in 1910 to 54 cents in 1914. Compared 

 with other countries, this country exceeds all others in imports of 

 this article. The balata rubber gum imported in 1910 amounted to 

 399,000 pounds and increased to 1,533,024 pounds in 1914, nearly all 

 of which came from Guiana and Venezuela. The guayule gum came 

 from Mexico, and amounted to 19,749,522 pounds in 1911 and 

 1,475,804 pounds in 1914. The gutta-joolatong or East India gum 

 came from the Straits Settlements, and amounted to 24,926,571 

 pounds, valued at $1,155,402, in 1914. The gutta-percha also came 

 from the Straits Settlements, and amounted to 1,846,109 pounds, 

 valued at $323,567, in 1914. 



The camphor gum was supplied by Japan, and is of two kinds — 

 crude and refined. In 1914 the imports of crude were 3,476,908 

 pounds, valued at $929,715, and the refined amounted to 566.106 

 pounds, valued at $182,790. The chicle gum (used largety for the 

 manufacture of chewing gum) came from British Honduras, Mexico, 

 and by way of Canada, and amounted to 8,040,891 pounds, valued at 

 $3,012,458, in 1914. The chicle gum brought from Canada is a Hon- 

 duran and Mexican product sent there to dry, as it dries best in a 

 cold country. The drying process reduces the weight about one-half, 

 which makes a saving in the duty. It is on the free list in Canada, 

 but is dutiable in this country at 15 cents per pound in the crude 

 state and 20 cents per pound dried or manufactured. The imports of 

 copal, kauri, and damar gum amounted to 32,693,412 pounds, valued 

 at $3,354,679, in 1914. The gambier or terra japonica gum came from 

 the Straits Settlements and amounted to 14,936,129 pounds, valued 

 at $571,067, in 1914. The gum shellac came from British India and 

 amounted to 16,719,756 pounds, valued at $2,689,269, in 1914. 



MINOR FOREST PRODUCTS. 



In 1914 the exports of wood pulp were 26,961,254 pounds, valued 

 at $529,741, and the imports were 1,138,727,195 pounds, valued at 

 $17,023,338. The imports came from Canada and the exports went 

 to Europe, yet those countries were the source of much more than 

 they received. In 1914 the exports of tanning materials were valued 

 at $666,880, while the imports were valued at $4,368,041. The dye- 

 woods and extracts imported were valued at $793,926 in 1914. In 

 1914 the value of the charcoal exported was $81,997, and the import 

 value was $60,634. About 99 per cent of the cinchona bark (from 

 which quinine is extracted) came through the Netherlands and 

 amounted to 3,648,868 pounds, valued at $464,412, in 1914. The cork 

 wood or cork bark imported in 1851 was valued at a little less than
