Note 15 — THE MOUNTAIN VILLA—LAGO DI COMO.

There are two kinds of winter avalanches; the one, sheets of frozen snow sliding on the surface of others. The swiftness of these, as the clavendier of the Convent of St. Bernard told me, he could compare to nothing but that of a cannon ball of equal size. The other is a rolling mass of snow, accumulating in its descent. This, grazing the bare hill-side, tears up its surface like dust, bringing away soil, rock, and vegetation, as a grazing ball tears flesh; and leaving its withered path distinct on the green hill-side, as if the mountain had been branded with red-hot iron. They generally keep to the same paths; but when the snow accumulates, and sends one down the wrong way, it has been known to cut down a pine forest, as a scythe mows grass. The tale of its work is well told by the seared and branded marks on the hill summits and sides.
