Sir Oliver Lodge, referring to the fact, that 'wireless messages' travelled further in the night time and belter ihijii between sunrise and sunset, pointed'out that high up the atmosphere was of too low a pressure, while below it was too high. Between the'two must lie a good conducting layer of air. This 'provided a steady constant means of travel at night, when the disturbing influence of sunlight was not present. Mr Balsillie, 'tlie Commonwealth wireless expert, stated that he had sent messages to a. distance of twp thousand miles at against 450 miles in the day-time. If the wave-length was increased, the range would be greatly extended in the daytime, but not at night.
