<i>Title:</i> And fall. Washington, D.C., April 9. Weather Bureau observers stationed along the principal rivers of the United States soon will be able to follow the rise and fall of nearby river merely by picking up a telephone and dialing a given number. Preliminary trials for the last few months here show that a new automatic sound river gauge effectively and economically supplies the facts weathermen need in forecasting floods and supplying other information on river conditions for many interests. More weather bureau stations will install the new gages as fast as possible. (1)A river gauge on the Potomac River in the Capitol, where formerly a U.S. Weather Bureau Scientist had to go to this gauge box to take a reading on the river's height, all he has to do now is to pick up his telephone, dial the number of Potomac River, listen for a gong, then a buzz and at last another buzz, and then he will know whether the river is rising or falling, 4/9/38
