LIGHTNING RODS.—Scientific Professors appear to be agreed that it is very important that lightning rods, in order to be efficient protectors, should terminate in moist earth, or which is better, in a pool of water. It would be but little trouble to dig a small pit, and supply it occasionally with water, in which the rod might terminate; and if to this is added two or three pounds of sulphate of iron, (copperas) once a year, the efficacy of the conductor would be still more perfect.
