In Martinique, for instance, there are three separate peaks, or groups of peaks--the Mont Pelee, the Pitons du Carbet, and the Piton du Vauclain.

But all have that peculiar jagged outline which is noticed first at the Virgin Islands.
Flat 'vans' or hog-backed hills, and broad sweeps of moorland, so common in Scotland, are as rare as are steep walls of cliff, so common in the Alps.

Pyramid is piled on pyramid, the sides of each at a slope of about 45 degrees, till the whole range is a congeries of multitudinous peaks and peaklets, round the base of which spreads out, with a sudden sweep, the smooth lowland of volcanic ash and lava.

This extreme raggedness of outline is easily explained.

The mountains have never been, as in Scotland, planed smooth by ice.
