There were many ques-tions that did not apply to American loco-motives, but questions might be formedthat would take cognizance of the di-versity of our motive power, the onlyrational explanation for the diversitybeing many men, many minds. If radical difference in practice madeno difference in the expense of operation,onlookers and those financially interestedmight be contented to regard the prefer-ences of different men with some indif-ference; but it is nearly always in di-versity of design that there is evidi ni iof good and bad, and the choosing of thebad implies that increased expense has. THE LOCOMOTIVE SUPERHEATER COMPANYS DEVICE APPLIED TO A ROTARY SNOW PLOW ENGINE. also reduces the fuel and water consump-tion, so that the danger of running out offuel and water at some point where anadditional supply cannot readily be ob-tained is considerably lessened. In a re-cent example of the application of super-heaters to a rotary snow plow on a West-ern road, the operating results obtainedshowed very plainly the advantages overa plow using saturated steam. The snow plow service on this railroadis probably more severe than anywhereelse in the country, outside of Alaska. Itis necessary to use plows throughout ninemonths of the year, beginning about themiddle of September, and in order tokeep the road open in the face of thenumerous heavy snow storms, the plowsmust be operated at maximum capacityfor considerable periods of time.
