ARTIFICIAL RAIN
Received Wednesday, 12.5 a.m. • SYDNEY, Feb. 11. On four occasions over differont parts of New South Wales rain has been pro duced reeently by dropping granulated dry ice through the top of towering cumulus clouds, said the chief of the division of radio physics of the Council for Scienti/ic and Industrial Research, Dr. E. G. Bowen. Some 200 to 300 pounds of dry ice has been dropped 011 each occasion. Rain has been observed failing from the bottoni of the "clouds first by radar and then visually. The rain did not begin failing immediately but usually 15 to 20 minutes later. ' ' Final details require a lot of e.xperimentai work which may run into several nionths and even years. It is too early to prophesv what practica! use can be. made of§the discoverv, " he said. ' ' We may succeed in sonnT parts of Australia in produeing rain over a limited area at the expense of other areas. A few hundred x>ounds of dry fice costs only £20, but it may produce anything from 10 to 1U0 tons of rain."
