number of ties and cords that can be cut from trees of different 
sizes; the figures do not represent amounts actually cut. 
The information contained in Tables 5 and 6 will be found useful 
in calculating the numbers and grades of ties that can be obtained 
from trees of different sizes. The sizes of the standard grades of 
ties are: No. 1, 6 by 6 inches; No. 2, 6 by 7 inches; No. 3, 6 by 8 
inches; No. 4, 7 by 8 inches; No. 5, 7 by 9 inches. The standard 
lengths are 8 and Sy 2 feet. Table 6 shows the number of ties by 
grades that can be cut from trees of different sizes, no allowance 
being made for defects. For example, trees measuring 15 inches 
in diameter at breastheight and 60 feet in height will, on the 
average, cut out three grade No. 2 ties, one grade No. 4 tie, and 
one grade No. 5 tie. Table 5 gives the total number of ties without 
specifying the grades. Copies of specifications for ties may be 
secured from the local railroad agent or may be found in Farmers' 
Bulletin 1210, " Measuring and Marketing Farm Timber."
