RAILWAY AND LOCOMOTIVE ENGINEERING. 339 Feed-Water Heating in Egypt Some very important work in thematter of feed-water heating in loco-motive practice has been done on theEgyptian State Railways by Mr. F. , the chief mechanical en-gineer of the Egyptian roads. The re-sults of his extensive experiments andtests have been published in a series ofarticles in London Engineering, fromwhich we make a few extracts.

Wemay here say that the eminent workerin this field is a grandson of the famousRichard Trevithick who, in 1803, builtthe first locomotive to run on rails. Dealing with the matter of feed-waterheating, we are told: That feed-waterheating has been brought within therange of practical application is provedby the fact that workable systems, alloffering more or less economy, havebeen devised both here and a smaller economy is only pos-sible with some than with others, sev-eral systems have passed well into thepractical stage. On the Egyptian StateRailways experimental work, extendingover some ten years, has enabled Mr. Trevithick, M. Inst. , the chiefmechanical engineer, to produce anefficient feed-water heating system, and,carrying the work a stage
