It has recently been suggested that many of the dry valleys which are found in limestone districts owe their formation to subterranean solution, and not to surface-erosion; in other words, that they are the work of subterranean watercourses which, by dissolving the rock substance, have caused subsidence of the surfaces overlying the lines of such watercourses.
