A marked feature of the geology of the West Indies is found in the extensive deposits of massive white limestone common to all this part of the world. This formation, though hard and compact, disintegrates freely; tall cliffs and broken rocks are honeycombed with openings and pit-marks, presenting a rough jagged surface, which is sometimes almost impassable. The Cockpit country where this formation is typical is situated in the west central part of Jamaica, and comprises an area some ten by fifteen miles in extent, and for the greater part one vast labyrinth of glades among rough cliffs, with here and there patches of smoother ground, and at other places, coming one after the other, a general collection of impassable sink-holes, called cockpits. The impression one gets in first visiting this region is that it is of little interest; just a path between a few not very high cliffs. There is such a sameness about it all that one is constantly expecting the next turn to lead out into the open country, or to a cultivated estate. After a few hours’ hard scrambling one realises that here in truth there is a wilderness of rocks. A large part of the Cockpit country has never been explored, nor is it probable that it ever will be, because the land is useless. One can cross the district from north to south, and east to west, and go all round it; sufficient to show that there is nothing to compensate for the effort, and that one part is quite similar to all the others. The elevations averaged from 1400 ft. to 1500 ft. In the glades I noted aneroid readings as low as 800 ft.; while on some of the ridges which cross this district N.E. and S.W., bending at times N. and S., I took readings as high as 2300 ft. These are the extremes, the average variation is about 200 ft.; but these elevations are abrupt and almost precipitous over nearly all the region. In 1898 there arose, owing to a not unfrequent source, disputes about land, some slight trouble amongst the Maroons of Charles Town, which was, however, effectually suppressed by the prompt action of the general commanding the forces. It, however, gave to the late Phil Robinson, who was in the island at the time, an opportunity to write an article for the “Contemporary Review,” entitled “A Dress Rehearsal of Rebellion among the Maroons at Annotto Bay, Jamaica.”
