heart of an old tree, in this way, by some opening near the roots, and burns away the inside, leaving merely a gray outer shell. 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. If the flames are once fairly kindled in dry weather, they will spread in all directions as the wind varies, burning sometimes for weeks together, until they have swept over miles of woodland, withering the verdure, destroying the wood already cut, and greatly injuring many trees which they do not consume. Several years since, in the month of June, there was quite an extensive fire on the eastern range of hills; it lasted for ten days or a fortnight, spreading several miles in different directions. It was the first important fire of the kind we had ever seen, and of course we watched its progress with much interest; but the spectacle was a very different one from what we had supposed. It was much less terrible than the conflagration of buildings in a town; there was less of power and fierce grandeur, and more of treacherous beauty about the flames as they ran hither and thither along the mountain-side. The first night after it broke out we looked on with admiration; one might have thought it a general illumination of the forest, as the flames spread in long winding lines, gaining upon the dark wood every moment, up and down, and across the hill, collecting here and there with greater brilliancy about some tall old tree, which they hung with fire like a giant lustre. But the next day the sight was a sad one indeed:
