However, exactly the same effect takes place in’ downspouts and water pipes; though, of course until the was invented, no one knew it. To set the minds of the red JepGe at rest, we asked Charles P. Steinmetz, who has made a special stud y of lightning and has produced artificial lightning on a small seale, to make a ment regarding the lightning hazard rid Dr. Stein. ‘that such installations will attract trical disturbances, or constitute menace, provided reasonable care and precautions are taken when the installation is made, It is to be assumed that the radio installation is made by some one acquainted with clec- trical matters as well as the theory If this is so, and pains are taken safeguard is provided in my opinion, be radio. to see that every for, there would not, any greater danger than from a_tele- 1 electric light: installation. autions referred to by Dr. Steinmetz can be summed uy follows: Keep the outside part of the aerial at least five inches away from the house; and at the point of entry, provide an approved lightning arrester connected to a good ground. — If this is done, and light- ning should strike the house, the occu- pants can comfort themselves with the reflection that the house would have been uck even if there had been no radio allation. THE contour of the country has a strong influence on the distance of reception. This was shown recently by an interesting test made with a receiver mounted on a Lackawanna Railroad train en route from New York to Buffalo. The results obtained were good when the train was running through open country; phone or The ¥ very good bodies of water; poor in’ mountainous districts; and very poor in the midst of rests. Curiously enough, however, no ial reduction of signals was noticed when the train was in deep cuts. Consequently, radio listeners located in the open plains or beside the or the Great Lakes have a great advantage over those in cities or mountainous regions. ‘They have, as it were, reserved seats at the radio entertainment.
