Not illustrated. 1904 edition. Excerpt: ...the Atlantic on board the steamship Philadelphia, in February, 1902, viz.: that in long distance wireless telegraphy, a given transmitting arrangement is effective over a greater distance by night than by day. Practically this means that it is rather more difficult to send Hertzian waves long distances through that portion of the atmosphere facing the Sun than that portion turued away from it. The same thing may be expressed by saying that it requires a more powerful wave to traverse the Sunlit air. The effect is not detectable under a distance of several hundred miles, but in his transatlantic experiments in 1902, Marconi found that the waves sent out from a particular aerial and transmitter at Poldhu were detectable on the Atlantic at a distance of 2,100 miles by night, but only about 700 by day. Since that day, by modifications of the transmitting plant he has been able to greatly extend the daylight distance." Prepared By J. D. Thompson. Abbe, Cleveland.
