GEODETIC SURVEY

months, arrived in Williams on Tuesday of last week, moving from Mcclellan, their last stop. The party occupies two outfit cars. leased from the railroad company, which were fitted up at San Bernardino as comfortable and commodious quar ters for the men. The party carries it's own cook and a complete mess equipment. and the men live well at all times.
 The party is engaged in extend ing the precise levels eastward from Goffs, California. which will eventually extend to Fl Reno, Oklahoma, a distance of over one thousand miles. The line is link in the vast network of geodetic lines which cover the entire country. At Goffa it is connected with the coast and geodetic surveys Southern Pacific connection, running from the transcontinental line to tide water at San Diego; at El Reno it joins system of leveling carried from the Gulf of Mexico to Canada along the Ninety Eighth Meridian. Geodesy, of which precise level ing is branch, is practically precise surveying of the highest at tainable accuracy. In country as large as the United States, where many surveys are made and where boundary lines of states and coun- ties follow the arcs of latitude and longitude, it is essential that all the diverse surveys should be united by a common "control," or datum to which all such work can be re- ferred. This is done by the Coast and Geodetic Survey, and it has covered the entire country with lines of precised levels and network of triangulation. This is known as the "Unit States standard datum" and the work of the geological sur veys, the land office, state, county and city surveys, are referred to it as final.
 Two years ago, in connection with their map surveys in various parts of Arizona, the geological survey ran line of precise levels from the Coast and geodetic surveys line in California eastward over the South ern Pacific railroad to Maricopa; north to Ash Fork, and eastward over the Santa Fe beyond Flag staff. At Ash Fork the two sur veys have met. and the difference in elevation obtained in a circuit oi over one thousand miles is only slightly more than one foot.
 The party consists of the follow ing members: Henry w. Maynard of Washington. D. O., in charge; L. J. Van Orshoven of Los Angeles Norman E. Lynch of Washington, D. G.; Geo. w. Barnard of Los Angeles; H. o. Holloway of Sheri. dan. Wyoming; J. P. Culpepper ol Los Angeles; s. G. Neal of Los Angeles.
 On Thursday of last week the party was temporarily suspended the members leaving for the Grand Canyon, where this week was spent in the inspection of the worlds greatest wonder. The few days rest from work was greatly enjoyed by all.
 Before leaving for the Canyon MT. Maynard gave the represen- tative of THE NEWS a pass to the cars, occupied by the party. The quarters were thoroughly inspected and in the order every article was found is worthy of comment. The costly instruments looked excellent to the newspaper man although he does not know thing about their usefulness.
 Last week MT. Holloway of the party sustained painful although not serious injury while the party was working near Mcclellan. The velocipede car on which he wat riding suddenly left the track bringing his right foot in contact with the badly worn rail. A piece of rustv iauued stea1 ovar tbra.
