The promotion of the rapidity and accuracy of levell- ing is one of the most important features of modern engin- eering. By means of a system of precise levelling, a net-work of lines establishing standard bench works, has been run throughout this country, and all constructive orerations are referenced from these benches. This work has been accomplished by the Coast and Geodetic Survey, together with the lines of levels taken by the Geological Survey. On account of the importance of this work, much at- tention has been paid to the improvement of instruments to be used. One of the most modern is the precise level re- cently adopted by the United States Coast and Geodetic Survey, and the determination of the capabilities of one of these instruments is the object of our research. The instrument used was the United States Coast and Geodetic Survey Frecise Level No. manufactured by Mann and Company of St Louis, Missouri, U. S.A. This level was in factory condition, never having been taken from the box until the beginning of this work. With the aforesaid object in view, a line was selected about ten miles long, extendinz from a bench work cut in THESIS stone window-sill of Piatt's power house in Lansing to a bench work on corner stone of foundation of Lake Shore depot at Dimondale, Michigan. The general direction of the line was southwesterly throush a slightly hilly country. The levelling party consisted of three men, their du- ties beins as follows:- (1) Instrument man; (2) Red man; and (3) Aman to take notes and keep the instrument shaded with an umbrella whenever the sun shone. The general atmospheric conditions were comparatively favorable for working. Before beginning the test, the instrument was adjusted until the error of closure was only $#m.m. for 100 feet. Permanent bench pare (I) north side of Piatt's power house, cross-notched on top of east end of stone sill of east window, The followins is a copy of notes taken wh:le running line. 93761 84.33 22.20 DIRECT LINE.
