Now that the American com-mittee is taking up its work again actixely, with meet-ings of the research sub-committee held on the last Fri-day of each month, it is appropriate to review the wholeprogram of researchon prevention of elec-.

Those who wereconcerned with theoperation of electricrailways in the nine-ties and the earlyyears of the presentcentury will recall theincredulity and sur-prise attending thefirst evidences of stray-current electrolysis, and how this surprise was fol-lowed by dismay as increasing numbers of pipes vi^ereunearthed showing the ravages of unconfined was a phenomenon entirely new and unforeseen to therailway engineers as well as the pipe and cable-owningcompanies, and one for which no effective remedy wasknown. In those early days the return circuit was notgiven the attention that it now receives, partly becausethe importance of the electrolysis problem w^as not ap-preciated, partly because of the primitive state of
