COMPARATIVE COST OF POWER. In connection with the accompanying tables show-ing the cost of electric power we publish, by permis-sion, from Manifold & Pooles Straight Line Engi-neering Diagrams, one of a new set of ten which hasrecently been added to this collection. This diagramgives a graphic representation of the comparative costof power from different prime movers and may be used as a basis for determining themost economical power source. As will be noted from the dia-gram comparison is made betweena distillate engine, a crude oil en-gine, a non-condensing steam en-gine, a condensing steam en-gine and an electric motor at vari-ous prices for fuel or costs do not include labor,water, maintenance, depreciationor interest, being for fuel figures are based on averageconditions for Pacific Coast prac-tice. Corresponding costs may befound along the same horizontalline. For instance we find thatthe power developed by a dist
