The boiler design is the result of a very careful study ofboiler proportions and construction, every care being takento insure ample steam generating capacity, combined witheasy steaming qualities. The smallest details of construc-tion were given close attention with ease of maintenance iuview. The capacity of the boiler in relation to the cylinderrequirements is per cent, based on Coles ratios. The 631 632 RAILWAY MECHANICAL ENGINEER Vol. 93, No. 11 ^^.
