The per cent of organic matter in the wood of the pear, = 9.79. 

 The wood of the pear is white, soft and compact, and easily 

 wrought, and may be used in the place of box, for wood en- 

 gravings. 



The Dog-wood (Cornusflorida), which is also a compact wood, 

 gives 11.16 per cent of coal. 



The Hickory, when seasoned, gives the largest per cent of ash, 

 of any wood experimented upon — amounting to 7.30, equal in 

 amount to the bark of most trees. 

 Remarks on the foregoing tables. 



1. The inorganic matter exists in the largest proportion in the 

 bark of the trunk. 



2. In the wood, it is usually larger in amount in the outside 

 than inside wood. 



3. The amount of ash in the small limbs usually exceeds that 

 on the trunk. 



4. The amount of ash in the bark of the limbs is less than in 

 the bark of the trunk. 



5. The amount of inorganic matter sometimes varies in the 

 same species. Those trees which have grown slow, seem to have 

 the largest amount of ash. 



Results of the Analysis of the ash of several Forest and 

 Fruit Trees, which have been obtained by methods described 



IN THE foregoing SECTIONS.
