A STUDY OF THE REDWOOD. 



27 



Table 7 shows the relation between sapwood and heartwood for 

 diameters of from 4 to 23 inches, indusive. The amount of sapwood 

 varies both with the diameter and the age. This tal)h; was constfucted 

 from measurements of trees taken at Crescent City, Eureka, and 

 Areata, which were used in the volume table, and of 4(10 trees at Trin- 

 idad too small to be used in the volume table.

WHERE THE TABLES APPLY. 



The tables given in this bulletin furnish the most accurate knowl- 

 edge of the Kedwood's growth now available. The Crescent City, 

 Eureka, and Areata figures are applicable to Redwood flats, where the 

 ground is low and moist. The Trinidad tables ma}^ be applied to all 

 that great body of Redwood of the slope type which occupies high 

 lands and steep slopes. 



CONCLUSIONS. 



THE SIMPLEST MANAGEMENT THE BEST. 



The narrow profits of Redwood lumbering prevent any but the 

 simplest systems of forest management. Excellent results can, how- 

 ever, be accomplished by inexpensive methods. 



WHAT ONE COMPANY HAS DONE. 



An interesting case of conservative Redwood management is found 

 in Mendocino County, where the Mendocino Lumber Company has
