It is. CASTING IN TEMPORARY REHEATING FURNACE roughly estimated that the value of the casting was$300, and to have procured a new one would have takenat least twenty-five days. The time actually requiredto cut the casting was three days. The welding tookone and one-half days more, and transportation to andfrom the plant consumed one week. VIEW SHOWING FINISHED WELD AND SECTION THAT WASREMOVED Minor Economies on Small Roads Strictly speaking there are no minor economies inelectric railroading, in view of the small units intowhich income is subdivided. Among the lesser methodsof saving money on the line, in the shop and carhouse,however, are many which are the result of experience,and they all count in the net earnings. Thus one com-pany operating about six cars normally, and twenty-oneon pleasant Sundays and holidays, totaling seventeendays yearly as a maximum, generates its own electricpower in a 350-kw unit in the former case, and buysextra power from an adjoining system when the peakscome.
