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 stumps 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.
