DROUGHT FORECASTS
TELLING WEATHER BY TREES. Dr. Julian Huxley has been telling the Royal Geographical Society what is meant by a dendrochronologist. He is one who investigates the climate of the past by measuring the rings of the trees; he can tell how the climate has varied by measuring the change in the thickness of the rings. Each year the tree forms a ring, clearly discernable. The wetter the year the thicker the ring. Most interesting results have been obtained by this method, especially in the Arizona Desert. The method is being adopted in the Tennessee Valley in the United States to ascertain the maximum drought to be expected, and thus to find out whether the reservoirs will always supply enough water for the power that is required.
