Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . tioned and disposed as to reduce thelength and volume of the smoke box to,or nearly to, the minimum, and to makethe front a selt-cleaning one, the uselesscinder hopper being therefore dispensedwith. The fallacy of the claim made bythe advocates of the extension front thatit acts as a spark retainer has been sogenerally recognized, and the dwindlingdown of its proportions in recent ap-proved practice is so marked, that a dis-cussion here of its unmechanical theoryand practical objections would needless-ly consume space. The Lake Shore de-sign evidences that all the netting areathat is necessary can be located in asmoke box whose front is only 28 the center of the exhaust pipe, andit will be readily seen that it could bemade even shorter if desired. The Muhlfeld design is also a self-cleaning front, and, except as to the sub-stantially horizontal plate which cuts offthe upper portion of the smoke box from. FIG. 8. probably be neither useful nor interest-ing, even if space permitted, to presentmany examples, and the two followinginstances, both of quite recent practice,which have been selected as being fairlyrepresentative, and worked out on soundtheory and correct application, will suf-fice to enable an intelligent conclusionto be arrived at as to the principles 01construction which seem best fitted toanswer the present conditions of rail-road service. The first of these, illustrated in Fig. 7,is the design of Mr. J. E. Muhlfeld, re-cently of the Intercolonial Railway, ofCanada, on which road it is stated tohave been applied with excellent resultsto 25 engines. While it was doubtlessoriginal with Mr. Muhlfeld, its meritwill not be at all diminished by the factthat it is essentially a reproduction of aplan proposed by Zerah Colburn in an article published by Colburn inthat year, after correctly slating that thevolume of the smoke box should be re- subs
