This toirestrial surface was overflowed by water for a very long time inhabited by Nniadites and Cythere. This, it will be observed, implies subsidence of a terrestrial surfivce and its long submergence; and I may remark, once for all, that the appearances of the whole section imply continuous subsidence, only occasionally interrupted by elevatory movements. The bituminous limestone which marks this submer- gence is again succeeded by coal, again submerged under water inhabited by mollusks, Cythere, etc. The succeeding group marks the filling of the quiet waters tenanted by Naiadites with thick deposits of clay and sand, and in one little bed, about three inches in thickness, filled with the shells of the little lund-snails known as Pupa vetusta and Conulus prisons, it shows eviilcace of neighbouring woods or swamps, from which some gentle stream must have drifted these little shells over the muddy bottom. Subdivision IX. is a fine series of underelays and coals, alternating with mussel-beds. It contains seven distinct soil-surfaces, the highest* supporting an erect tree, which appears as a ribbed sandstone cast, five feet six inches high, nine inches in diameter at the top, and fifteen at the base, where the roots began to separate. This tree, being harder than the enclosing beds, at the time of one of my visits stood out boldly at the base of the cliff, nearly three-fourths of its diameter and the bases of three of its four main roots being exposed. Five of the underelays support coals, and in three instances bituminous lime- stones have been converted into soils, none of which, however, support coals. The last of these
