The conclusions drawn by the test department from all of thevarious tests are as follows; 1. A front end arrangement has been developed for the Eclass, which, while self-cleaning, maintains the boiler capacity ormaximum evaporation fully equal to that with the standard frontend arrangement. 2. With friable coals where large quantities of cinders areformed, the boiler capacity will be increased on long runs, onaccount of the smoke-box being kept clear of cinders whichwould obstruct the draft. 3. The front end arrangement recommended for the E classof locomotives is that shown in Figure 4, to be used witli anexhaust nozzle of 5^4 hi. diameter. 4. The outside and inside stacks as now used on this classof locomotive appear to give better results than can be obtainedwith the form recommended by the Master Mechanics Commit-tee, and it is thought advisable to retain them. 5. The best results were obtained when the passage for thegases under the diaph
