The little old squat farm houses, with their dormar windows, will be supplanted by elegant villas, and neat cottages and stately castles, and the hundreds and thousands of monuments erected in memory of the dead of a former generation, and now slanting to the horizon, and many of them dilapidated and disjointed, will be eagerly sought out by some old Mortality, and their nearly obliterated insignia restored and redeemed from oblivion.
