The next place of interest before which we brought-up was the island of Staffa.  We could see in the distance the islands of Coll and Tiree. The latter, only about a mile and a half in circumference, rises out of the ocean to the height of about one hundred and forty-four feet. Before landing we sailed along the eastern shore, examining the wonderful caves and the fine colonnades which form its sides.  One might suppose that it was rather a work of art than thrown up by Nature.  The yachts were hove-to, and we pulled off to examine the caves in the boats.  One is known as the Clam Shell Cave, another as the Herdsman's Cave, and a third is denominated the Great Colonnade and Causeway.  Then there comes the Boat Cave, and Mackinnon's Cave, and lastly, the most magnificent of all, Fingal's Cave.  Into this we at once rowed.  I scarcely know how to describe it.  On either side are lofty columns, mostly perpendicular, and remarkably regular, varying from two to four feet in diameter.  The height of this wonderful cavern is sixty-six feet near the entrance, but it decreases to twenty-two feet at the further end; it is two hundred and twenty-seven feet long, and forty-two wide. At one side is a causeway formed of the remains of broken columns, upon which people can walk to the very end.  We next pulled into what is called the Boat Cave, where columns are even more regular than in Fingal's Cave, but it is much smaller.  Our last visit was to Mackinnon's Cave; its sides are perfectly smooth, it is about fifty feet high, and forty-eight broad, the roof being almost flat.  We pulled on for two hundred and twenty-four feet, until we reached a beach of pebbles at the further end, when we appeared to be in a vast hall. Several places, where the tops of the columns crop up, have the appearance of a tesselated pavement.
