Table 6 shows the number of pile feet in trees of diameters from 18 

 to 28 inches, inclusive. It was obtained from stem analyses taken at 

 Crescent City, Areata, and Eureka. Assuming that nothing which 

 will not furnish a log 30 feet long and 10 inches in diameter at the 

 small end is available for piling, the smallest tree to contain a pile was 

 found to be 18 inches in diameter breasthigh. The table follows:
