on the coast of Mull. The mouth is fortified by vast fragments of stone, over which we made our way, neither very nimbly, nor very securely. The place, however, well repaid our trouble. The bottom, as far as the flood rushes in, was encumbered with large pebbles, but as we advanced was spread over with smooth sand. The breadth is about forty-five feet; the roof rises in an arch, almost regular, to a height which we could not measure; but I think it about thirty feet.
This part of our curiosity was nearly frustrated; for though we went to see a cave, and knew that caves are dark, we forgot to carry tapers, and did not discover our omission till we were awakened by our wants. Sir Allan then sent one of the boatmen into the country, who soon returned with one little candle. We were thus enabled to go forward, but could not venture far. Having passed inward from the sea to a great depth, we found on the right hand a narrow passage, perhaps not more than six feet wide, obstructed by great stones, over which we climbed, and came into a second cave, in breadth twenty-five feet. The air in this apartment was very warm, but not oppressive, nor loaded with vapours. Our light showed no tokens of a feculent or corrupted atmosphere. Here was a square stone, called, as we are told, Fingal's table.
If we had been provided with torches, we should have proceeded in our search, though we had already gone as far as any former adventurer, except some who are reported never to have returned; and measuring our way back, we found it more than a hundred and sixty yards, the eleventh part of a mile.
Our measures were not critically exact, having been made with a walking pole, such as it is convenient to carry in these rocky countries, of which I guessed the length by standing against it. In this there could be no great errour, nor do I much doubt but the Highlander, whom we employed, reported the number right. More nicety, however, is better, and no man should travel unprovided with instruments for taking heights and distances.
