THE weather forecast for London and the Channel was "light airs, fine generally, milder." Further down the fascinating column Hackness read that "the conditions over Europe generally favoured a continuance of the large anti-cyclonic area, the barometer steadily rising over Western Europe, sea smooth, readings being unusually high for this time of the year." Martin Hackness, B.Sc., London, thoughtfully read all this and more. The study of the meteorological reports was part of his religion almost. In the laboratory at the back of his sitting-room were all kinds of weird-looking instruments for measuring sunshine and wind pressure, the weight of atmosphere and the like. Hackness trusted before long to be able to foretell a London fog with absolute accuracy, which, when you come to think of it, would be an exceedingly useful matter. In his queer way Hackness described himself as a fog specialist. He hoped some day to prove himself a fog-disperser, which is another word for a great public benefactor.
