WATER-DIVINING is one of the superstitions that have justified themselves and developed into sciences. The man with the' hazel twig which gives such clear indication of the presence of subterranean water is known throughout the countryside. Serious business firms do not now disdain to call in the services of the professional diviners, of whom Mr. Tompkins is one. Listeners who remember his previous talk from London some time ago will be glad to hear more of his interesting lore this evening.
