When, however, a number of perpetual springs cluster together, or a rill, rivulet, or brook, runs through an estate in such a manner as easily to be improved or developed into an elegant expanse of water in any part of the grounds, we should not hesitate to take advantage of so fortunate a circumstance. Besides the additional beauty conferred upon the whole place by such an improvement, the proprietor may also derive an inducement from its utility; for the possession of a small lake, well stocked with carp, trout, pickerel, or any other of the excellent pond fish, which thrive and propagate extremely well in clear fresh water, is a real advantage which no one will undervalue.
