One would not expect the bark to be left in such cases, but the wood at the heart seems more inflammable than the outer growth. Whatever be the cause, such shafts are not uncommon about our hills, gray without, charred within.

There is, indeed, much charred wood in our forests; fires which sweep over the hills are of frequent occurrence here, and at times they do much mischief.
