Table 25 is similar to Table 23, except tbat 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.
