Table 25 is similar to Table 23, except that it represents an average stand without 
division into site qualities, and includes prop material to a top diameter of 4 inches.

Table 26 shows the average number of ties and the amount of prop material, expressed 
in board feet, for trees of different diameters irrespective of height. The table is 
based on about 90,000 old trees cut in extensive logging operations on the Medicine 
Bow National Forest, and includes allowance for all defect.
