“ In Burra there is no landing, but to the Men of Hirta only, in regard of the difficulty thereof; there being but about a foot broad of Landing-place, and that only to be attempted when the Boat rises. For their ordinary way is, when they come near the Rock, they turn the Boat and set the side to the Shore, two men, one at each end of the Boat, with two long Poles keeping it off, that the Waves dash it not so violently against the Rock, when it rises; at which time only the Fellow, who is to land, makes his attempt. If he miss his Landing-place he falls into the Sea ”
