Before entering into the detiils ofboiler design it is advisable to givesome consideration to the generalprinciples which pertain to the sub-ject. The object to be attained is theconversion of water into steam nt arapid rate, since the total weight vlboiler and water which can be carriedis very limited compared with thehorse power to be developed. Thi?object, namely, to obtain the greatesthorse power from the least possibleweight of boiler and water has I)eenthe principal reason why locomotivetoiler designers have hitherto led theway in the adoption of higher pres-sures, until recent years when otherbranches of engineering, such as tor-pedo boat builders, etc., kave found ii.

Now, with a bright light backof the red letters in the section he andhis fireman will always have the nextmeeting point staring them in the face,and it is not likely that they would for-get. When No. 7 is held up for ordersagain, engineer would take section fromcage and leave it with operator to bereplaced with one for next meetingpoint. Each section could be stampedwith the name of issuing office, and re-turned to the proper places by localtrains every day, thus insuring a suffi-cient supply for each station. E. C. .\ Furnace.
