Atypical arrangement is shown in the illustration. The headers are made of steel throughout, are located en-tirely outside of the hot gas path, and in the majority of the material and it thus presents a smooth external surface, offersminimum resistance to the flow of the gases and avoids seri-ous collections of soot that would interfere with the efficiencyand uniform operation of the superheater. This construe- September, 1919 RAILWAY MECHANICAL ENGINEER 555 lion also brings the steam into intimate contact with the gas-touched heating surface, and gives a low resistance to thellow of heat from the gases to the steam. The form of the unit is such as to permit free expansionand contraction of all parts. The tubes are bent on speciallydesigned machines that do not weaken them or reduce thesteam areas, .\mple provision is made to prevent the pipesfrom warjjing. In cases w
