TABLE 8. Cruises of 478.85 acres of western yellow pine in Latah County, Idalw. 



1 From Table 6. 



TABLE 9. Recapitulation of cruixes. 



1 The estimates include only yellow pine, which constituted but 53.34 per cent of the entire stand. A 

 pure stand would be heavier. 



In all tables a slight discrepancy will be noticed between the total 

 number of cords of stumpwood, when added and when computed. 

 This is due to the dropping of decimals and the using of even numbers 

 only in cruise tables. 



The average stand over large areas of yellow pine in Idaho is from 

 5,000 to 15,000 board feet an acre, or from 10 to 30 trees, '24 inches in 

 diameter on the stump, the volume of stumpwood running from *2\ to 

 8 cords an acre. For more open stands the number of Mumps will 

 be less, but such stumps are generally larger and consequently more 

 resinous. Therefore the volume of " pitchy" wood will be consider- 

 able, but can be determined only by a field survey of each region.
