On June 25, Herbert C. Hoover and General Pershing were honored by Oxford University with the degree of Doctor of Civil Law. The ceremony was held in the Sheldonian Theater. It was the culminating feature of the annual L Ecnaenia, or commemoration exercises. Both General Pershing and Mr. Hoover were greeted-heartily when the group filed into the theater, the great audience rising as the distinguished visitors entered and proceeded to their .places on the rostrum. Others upon whom. the degree was conferred were Baron Makino, head of the Japanese Peace Conference delegation; Marshal Joffre of France, Vice Admiral Sir David Beatty, Field Marshal Sir Douglas Haig, Major Gen. Sir Henry Hughes Wilson, Chief of the British Imperial Staff, and' Vice 'Admiral' Sir Rosslyn Wemyss, First Sea Lord. Former Premier Orlando, of Italy, and Premier Ignace Paderewski, of Poland, received the degree by proxy.

THE second award of the Saunders Gold Medal for "distinguished achievement in mining," of which the first was awarded last year to the late D. W. Brunton, has been made to Herbert Hoover. The main events of Mr. Hoover's life are so familiar to all through the numerous journal articles about him and his work, and the interesting biography written by Vernon Kellogg, that no attempt will be made here to touch on anything other than his achievements as a professional mining engineer, for which the award was made. He graduated in mining from Leland Stanford, Jr., University in 1895, but had served as an assistant to Dr. Branner on the Arkansas Geological Survey in 1893 and had also worked two sum-mers as an assistant to H. W. Turner and Waldemar Lind-gren on U. S. Geological Sur-vey work in the Sierra Nevada around Lake Tahoe, and on the American River. Immediately after graduation he got "a job" underground at Grass Valley, and soon rose to be night shift-boss. He then secured employment with the late Louis Janin and made such a good record as office and field assistant that he was soon placed in charge of a small mine at Carlisle, N. M. In 1897, Mr. Janin recom-mended him to Bewick, More-ing & Co., who were looking for an examining engineer for their staff in Australia. Two years were spent in hard work there which was done so creditably that his princi-pals held him and his judg-ment in the highest regard, and he came to the head of their local organization. Among the properties which he acquired for them was the Sons of Gwalia.

THE John Fritz Medal Board of Award, at its regu¬lar annual meeting Oct. 19, awarded its gold medal to Herbert Clark Hoover. Thus ended a process of selection begun a few years ago. The award was tentatively made a year ago by the Board, which is composed of sixteen recent past-presidents of the four national societies of Civil, Mining and Metallurgical, Mechanical, and Electrical Engineers, having together a membership of nearly 60,000. The sixteen members of the Board are: American Society of Civil Engineers : C. E. Grunsky, Robert Ridgway, George S. Davison and John F. Stevens ; American Institute of Mining and Metallurgical Engineers: William Kelly, J. V. W. Reynders, Samuel A. Taylor and E. DeGolyer; American Society of Mechanical Engineers: Fred R. Low, D. S. Jacobus, Dexter S. Kimball and Charles M. Schwab; American Institute of Electrical Engineers: Farley Osgood, M. I. Pupin, C. C. Chesney and Bancroft Gherardi.

INTRODUCTION Located on the Colorado River on the Nevada-Arizona border about 56 km (35 miles) southeast of Las Vegas, Nevada, Hoover Dam is a gravity arch dam 221 m (726') high for electric power generation and water supply. The head waters of the dam form a large reservoir, Lake Mead. The dam is equipped with two emergency spillways, one in the Nevada abutment and one in the Arizona abutment. Both spillways which are concrete lined and 15.25 m (50') in diameter, were intended for use only if Lake Mead is full and incoming flow of the Colorado River exceeds the discharge capacity of the turbines and regular bypass conduits. In the spring of 1984, a combination of rain and unusually rapid snow melt required the opening of the spillways for only the second time in the 50 year history of the dam. As in the previous use in 1942, the massive discharge of water through the tunnels resulted in severe damage to the concrete Linings of both tunnels. This damage is the result of cavitation which occurs as the discharge water flows at very high velocities over minor irregularities in the concrete lining. The U.S. Bureau of Reclamation has long been aware of the cavitation effect which occurs during these high volume discharges and has been studying solutions. One solution to the problem is to induce air bubbles into the flowing water to eliminate the vacuum associated with cavitation. This solution had been implemented at Yellowtail, Flaming Gorge, Blue Mesa, and Glen Canyon dams by constructing an aeration slot in the inclined portion of their spillway tunnels. Since the spillways of Hoover Dam were already in need of repair, the BUREC decided to construct similar facilities in each of the two 15.25 m (50') diameter spillways coincidental with the other repairs required.
