September 15, 1894. The Mason-Hoover excavating machine used in Section H. The narrower width of the Main Channel in the Earth Section allowed for this machine to span the area to be excavated. It rode on rails on each side of the Main Channel and the extended arms on each end cantilevered over the spoil areas. A continuous belt from end-to-end of the structure was used to transport the excavated soil to the spoil area at either end. (MWRD photo, disc 7, image 27)
