As in the case of ash, the yield steadily decreases with in- 
creasing diameter of stem. But yield is not the only factor, 
for the lumber from the different diameter classes has dif- 
ferent values and before discussing the value of the yield, the 
variation in price according to the average width of board 
will be considered. 
C. RELATION oF WIpTH TO PrRIicE 
It is well enough known that the narrower the board used 
in any particular industry, the greater the percentage of 
waste. Hence, it is to be expected that the value will bear 
some relation to the percentage of useable lumber in a board. 
The percentage of waste rapidly decreases as the boards in- 
crease in width until, above a certain width, the difference in 
the amount of loss is negligible. Hence, with wide boards the 
value ought not to change. 
In local hardwood using industries, this was found to be the 
case and prices were obtained for oak from both chair manu- 
facturers and wholesale dealers. It was found impossible to 
get a series of values for ash, partly because it is not greatly 
used locally and partly because it is used in certain specific 
industries where only particular qualities or sizes are re- 
quired, such as tennis rackets, baseball bats, oars, motor 
cars, airplanes, etc. On account of its use for these special 
purposes higher prices are paid for ash than for oak. Oak, on
