NOTES TO TABLE 8, TABLE 9, TABLE 10, 

 TABLE II. 



It is highly important for every millman to know the actual 

 cash value of the lumber in a given log. 



In order to get the necessary information, the various per- 

 centages of lum'ber grades contained in a log of a given des- 

 cription (see tables 4, 5, 6 and 7,) were multiplied by their re- 

 spective yard prices, vs^hich at the time of my investigations 

 were assum'ed to 'be the following pea* 1000 feet board meas- 

 ure: 



Of course the prices of any product are subject to variation, 

 according to times and localities. However, the following 

 babies may still be applied with slight modifications, if the 

 prices rise 10 per cent, higher or fall 5 per cent, lower. A 

 child can make the necessary corrections. 



The tables will lose their value only when the different 

 grades of lumber show a decidedly divergent tendency of 

 change for better or worse; when, for ir^tance, Is and 2s gain 

 10 per cent., whilst common and cull lose 10 per cent. 



The "Values of lumber sawed out of logs" are grouped in 

 four tables, according to the four grades of logs distinguished. 



Table 8 shows the values of lumber from logs free from de- 

 fects. 



Table 9 shows the values of lumber from logs with one or 

 two detfedts well located. 



Table 10 shows the values of lumber from logs with three to 

 five dietfecte well looaited. 



Table 11 shows the values of lumber from cull logs.
