2 In case of chestnut oak the mean is not the average, since the slab represented more runs than heart. 



In yields of alcohol per cord, the different species of ash, tanbark 

 oak, and eucalyptus are practically as good as beech and maple. 

 Chestnut oak, swamp oak, slippery elm, and white elm (heartwood) 

 did not compare so favorably with beech and hard maple, but all of 

 them except chestnut oak gave higher yields than birch. 



Tanbark oak, California black oak,^ and eucalyptus are the only 

 species in this group that gave as high yields of acetate of lime as the 

 standard species, although swamp oak and chestnut oak gave prac- 

 tically as good yields as hard maple. Tanbark oak gave a higher yield 

 of acetate than any other species so far tested. The remarkable yield 

 of acetate from California black-oak limb wood is due in part to the 

 very heavy wood. It must be remembered, however, that commer- 

 cially a cord of limbs would contain much less solid wood than a 

 cord of body wood and the yield would be reduced proportionately. 



Table 3. — Relative yields of commercial alcohol and acetate per cord. 



[Average yield from heartwood of beech, birch, and hard maple from Indiana and Wisconsin=100 per 

 cent. Acetate=316 pounds; alcohol= 10.63 gallons.]
