Protection from Lightning.
Professor Henry, of the Weather Bureau, at Washington, in a bulletin just issued, entitled “Cheap protection from lightning,” says that more attention should be given to the question than is now devoted to it. He lays especial amphasis on this point, in view of the fact that 700 to 800 people are killed, twice as many injured, and an immense amount of property destroyed by lightning every year Professor Henry shows how lightning rods that are “inexpensive yet ef fective” may be put up by anybody. The following is bis list of necessary materials: Enough galvanized iron telegraph wire to serve for the rod a pound of galvanized iron staples to hold the wire in place, a few connecting tees, and a pound of aluminum paint. While iron is not so good a conductor as copper,” says the professor, “it is less likely to cause dangerous side flashes, and it also dissipates the energy of the lightning fla-h more effectively than does the copper.”
