Laying out for boiler makers and sheet metal workers; a practical treatise on the layout of boilers, stacks, tanks, pipes, elbows, and miscellaneous sheet metal work . alve,and thus prevent it from seating in the same place everytime. This check should be located along the center line placing these things on so that they will look right with theother parts of the locomotive. Thus we have completed, in the limited space allotted, thegeneral lay-out of the various sections of the locomotiveboiler. Before bringing this series to a close, however, thisone thing should be remembered, that no matter how wellthings may be described or illustrated for the direction oflaying out a locomotive boiler, there is still that large ele-ment of judgment, depending upon experience, which wil!outweigh everything else. It is this personal contact with theactual work of laying out which brings to one that knowledgewhich enables him to meet these various difficulties of error,of inaccuracy, of defective material, and a hundred and oneother things which go together to make a good, substantial,and commercially successful locomotive boiler. i^o4 LAYING OUT FOR BOILER MAKERS. A FLUE AND RETURN TUBULAR MARINE BOILER, II FEET 6 INCHES DIAMETER BY 26 FEET 4 INCHES?

Of the innumer-able classes and types of boilers for the generation of steamfor use in marine installations, none has attained the degreeof all-around efficiency and excellency as now represented bya modern and well-designed boiler of the Scotch type. Thisstatement applies to a greater or less extent to boilers for sta-tionary uses, although, for reasons of expense principally, t
