TIES CHESTNUT TYPE. 



Table 28, which shows the yield in ties and additional cordwood, 

 was constructed from Tables 45-47, Appendix, on the same assump- 

 tions regarding the stand as in the case of the lumber-yield table. 

 The figures should therefore be discounted for a given stand by a 

 figure varying with the straightness, soundness, and clearness of the 

 timber. The yields are for both chestnut and oak ties. Although the 

 published specifications for ties do not consider black or red oak, 

 these are included for the reason given on page 45. If it is desired to 

 limit the application of the table to white oaks and chestnut, the 

 figures should be discounted by a figure in proportion with the 

 estimated number and size of red and black oaks per acre suitable for 

 ties at the time for which it is desired to determine the yield.
