NATURAL PHENOMENA GIVEN LATEST SETTING AT UNION

Professor McAdie Compares Cambridge Rainfall With Noah's Flood--Daly and Whipple Also Speak

The symposium given at the Union last night under the auspices of the Gamma Alpha Fraternity, the Scientific Society of the University, presented many amazing and interesting facts to the large audience attending.

Professor A. G. McAdie '85 emphasized the importance and possibilities of rain. The annual rainfall in Cambridge is forty inches. In comparing this with Noah's flood, he said, we should allow these forty inches to come all in one day and then multiply by one hundred. The resulting flood would cover Memorial Hall.

The heaviest twenty-four-hour rain in the United States occurred in Taylor, Texas where there fell in one day a total of twenty-four inches which is a little less than Cambridge gets in one year.

Professor R. A. Daly '93 in speaking of the "Ocean" showed startling figures dealing with the pressure it exerts upon itself. "If the ocean were not compressible," he says, "sea level would be 200 feet higher than it is now. It is to this fact, than the ocean can sit upon itself, so to speak, that we owe our present safety."

Professor G. C. Whipple described very clearly the methods that are at present used in conveying water to Boston, Los Angeles, and New York.
