Pumping- Rig at Sub-Station No. 4. The transformers may be moved forward out oftheir cells, but ordinarily the opening between the celland the operating room is closed by a counterweightedsliding door. Sub-station No. 3 is at Tres Vias and energizes,not only a section of the main line, but the branch intoOroville as well. This station is similar to No. 2 inall respects, except that the transformers are 300 each, and there are two 400 kw. motor-generator sets. Sub-station No. 4 is again similar to 2 and3 and is equipped with one motor-generator set. Thisstation is located near Gridley. At all the sub-stations, it is necessary to havewater for the various purposes of domestic supply,irrigation and as a means for cooling transformers,although some of the transformers are oil-immersedbut air-cooled. Water is near the surface of the groundat almost any point, but it is necessary to pump tank elevated to give the proper head for all pur-poses is supp
