Drooping fountains, overflowing vases, shells (as the giant Chama), cisterns, sarcophagi, dripping rocks, and rockworks, are easily formed, requiring only the reservoir to be as high as the orifice whence the dip or descent proceeds. This description of fountains, with a surrounding basin, is peculiarly adapted for the growth of aquatic plants. Both classes of waterworks successfully combine.
