Future Yield. — On the valuation surveys the smaller trees down to five 

 inches diameter breasthigh were counted and tallied. From the figures so 

 obtained, by the table of the growth of spruce given in Bulletin No. 30 (page 

 31), and from the volume tables, an estimate has been made of the future yield 

 of spruce on Townships 5, 6 and 4.1. 



These figures are given in the following table, which shows for the merchant- 

 able area on Townships 5, 6 and 41 the yields of spruce expressed in standards 

 which might be obtained after successive ten-year periods, and the number of 

 years which must elapse before an equal cut can be had, provided that the 

 diameter limit adopted now be adhered to then.
