a town of Spain, in the province of Cata- lonia, with 2800 inhabitants. It occupies the summit of a hill near the banks of a small river, the Cardoneria, a branch of the Llobregat. It is remarkable for the famous mountain of rock salt in its vicinity. It forms a mountain mass in the head of a valley, and is covered by a thick bed of a red- dish brown clay, and apparently rests on a yellowish gray sandstone, that slightly effervesces with acids. It is rather, according to Dr Trall (Geolog. Trans.), a valley filled with salt than a mountain of that material as commonly stated. The salt is generally more or less translucent, but large masses of it are quite transparent; and pieces cut from it are worked by artists in Cardona, into images, crucifixes, and many articles of an ornamental kind.
