We have often followed the remains of some friend, or parishioner, to the picturesque grounds of our own LAUREL HILL--we have _traced_ each winding walk among the groves and tombs of MOUNT VERNON, and gazed upon the various monuments, the sculptured tombs, the dark shrubbery, and encircling scenery of _Pere la Chaise_; but we have no where seen such combined beauties, and natural advantages for a rural cemetery, as in the grounds which we have here attempted to describe. And what will these grounds be some hundred years hence, when art shall have reared up in every vale, around the margin of every lake, and upon every hill-side a thousand marble monuments, and when a larger population shall be ensepulchred here, than the living mass of beings that now inhabit New York and Brooklyn? What multitudes and myriads will those two cities within the next hundred years send to be entombed here! How will the population of this subterranean city go on increasing, till all these acres are covered over with piles of human dust! And what a scene will be exhibited here, when the last trumpet sounds! What myriads will start up here at that call! "For all that are in their graves shall hear his voice and come forth!" And how solemn the truth which the Saviour subjoins,--"they that have done good unto the resurrection of life, and they that have done evil unto the resurrection of damnation!" I have lingered so long about the grounds of Green Wood Cemetery, that I can tell you nothing in my present letter about our excursion to Rhode Island. CHAPTER XIX. RHODE ISLAND.
