the Sierra in Merados in 1891 the winters snow had been unusual so that much snow was left throughout the summer in which fell the falls over snow. After much search no unusual condition in the atmos- phere of the time could be found to explain why this big snow fall. If we today can not ascertain the causes why should we not be ever the more cautious in regard to the fact. Meteorology alone will not explain these changes but in geology one should embrace all the types of conditions. David also pointed out the Douglas experiment was laid down over low altitude. He suggests a snow monsoon instead of the present rein monsoon. An aground then increase a decrease of heat during glacial climatic he thought it was the latter as in the River Cane. Of Australia all the reef cools vanish before the glacial conditions stir. He thought the main cause to be meteorology, not in altitude. Freck spoke along Davis' line and offers his remarks as in harmony with his views. Fairchild reputed that Chamberlin was not power as he was the greater authority on geology's climate interpretation.
