SCALPA, an island, in the parish of Strath (Isle of Skye), county of Inverness; containing 90 inhabitants. This is an island of the Hebrides, lying in the sound between the Isle of Skye and the main land; it is a high, bluff, and rocky island, about five miles in length and from two to three in breadth. The shores are low, and formed of a blackish-coloured argillaceous sandstone. In the highest part of the isle is a petrified rock of moss, in which are varieties of shells; and in many of the higher grounds are found great quantities of shells, several feet beneath the surface. The channel called the sound of Scalpa, separating the island from Strath, is about three-quarters of a mile broad.
