9% are blanks. Eighty per cent of the forest is managed as high 

 forest. 



In the State forests under working plans only about 14.3 cubic 

 feet per acre are cut per year. The net income is $.187 per acre 

 per year (figures of 1907). 



Hofmann describes the interesting minor industries of Camphor 

 gathering and of lacquer from Rhus vernicifera. The camphor 

 industry at present utilizes only 30% of the camphor in a tree. 

 Camphor is a state monopoly : the exports in 1906 were valued at 

 about $2,500,000.

This species is quite extensively used for 



Growth of ornamental planting in Switzerland, where 



Sequoia it thrives. Two specimens which in 1877 



gigantea were planted before the forest school of 



Zurich had to be removed in 1913 and 



were analyzed by Prof. Jaccard. 



One of these trees had been sickly for some time and had reached 

 only little over half the diameter and 20% less height than the 

 sound one, hence its record is of no value. The other, 45 years 

 of age, had attained a height of 66 feet and a diameter of 32 

 inches, with bark of 2 to 3 inches, a bark per cent of 24, and the 

 very low form factor of 24, the tree being beset with branches to 

 the very base. 



The quinquennial periodic increment of diameter ran from the 

 first five to the last five years as .08, .15, .26, .36, .47, .68, .59, 

 showing a culmination in the 35th year. The wood is extremely 

 light, its specific gravity being .37, with a moisture content of 

 80 to 88 per cent. 



The root system is described as consisting of a large ntmiber 

 (eleven) of stout roots, descending for a considerable distance 

 straight into the ground before branching or sidewise expansion; 

 the circumferences of this root system added together is 16 feet, 

 while the circumference of the tree at breast high measured only 

 8 feet.
