From the report ofMr. Carrington, of a partial examination made by him of the rangewest of Dolphin Island, it consists of calcareous tufa and conglome-rate, overlying which was argillaceous limestone of variouscolours and texture, extending to the base of the short spurs of theridges; above this was found black, bluish, and gray limestone,very compact and fine-grained, veined with calc spar; above this,again, was an inferior or earthy limestone, overlaid by a brownish-gray fossiliferous limestone, capped by an argillaceous limestone,which extended to the summit of the range. The vegetation wasthe ever-recurring artemisia, bunch-grass, and a few scatteringdwarf cedars not more than ten feet high.

The summit is some seventy feetabove the level of the water, and the island consists mainly of con-glomerate in horizontal strata, and varying much in the size of thecemented stones.
