The most magnificent of all known caverns, is that called Fingal’s Cave, in the Isle of Staffa, on the western coast of Scotland. Its length is 370 feet; and the height at the entrance of the cave is 117 feet.

Thousands of majestic columns of basalts support a lofty roof, under which the sea rolls its waves, while the vastness of the entrance allows the light of day to penetrate the various recesses of the cave.

The mind, says Mr. Pennant, can hardly form an idea more magnificent than such a space, supported on each side by ranges of columns, and roofed by the bottom of those which have been broken off in order to form it, between the angles of which a yellow stalagmatic matter has exuded, which serves to define the angles precisely, and, at the same time, vary the color with a great deal of elegance. To render it still more agreeable, the whole is lighted from without, so that the farthest extremity is very plainly seen; and the air within, being agitated by the flux and reflux of the tides is perfectly wholesome, and free from the damp vapors with which caverns generally abound.
