The iron wood is one of the instances in which I have found 

 the per cent of ash of the heart wood to exceed that of the sap 

 wood. The tree, however, from which the wood was taken for 

 the experiment, is a young, vigorous tree, about eight inches in 

 diameter. The seasoned wood from which the ash was procured 

 in the last analysis, was a small tree, though about one hundred 

 years old.
