This locomotive wasturned out of the shop March 24, 1907,and made 890 miles in freight service Air Heating Apparatus. Editor: I should like to point out to youthat one of the points raised by E. Wiley in the General Corres-pondence columns of your May issue,namely, the heating of the air for com-bustion before it it admitted to thefire, is now being tested in Englandon the London, Brighton and South1 oast Railway. The arrangement isthe patent of a Mr. Hammond and con-sists of two large casings on eitherside of the upper part of the smokebox containing a number of tubes opento the atmosphere at the leading end. The interior of the smoke box itselfis divided into two chambers, an upperand lower. The exhausts takes placein the top one and the gases of com-bustion are drawn through among theair tubes, heating their contents, whichare constantly displaced by the motionof the engine forcing them back to be-low the firebars, where they are ad-mitted to the HEAVY 4-6-2 ON THE LAKE SHORE. before being placed on her regularrun, between Jackson and Chicago, inpassenger service. April 2, 1907, theengine was placed in passenger ser-vice, hauling trains Nos. 23 and 36,each train consisting of about 425 tonsexclusive of the locomotive. On May 2, 1908, locomotive was ta-ken into the shop, after having made147,451 miles; 145,561 of which were inpassenger service. This gives an aver- I cannot say yet how the device isworking, but I think that this notemay interest some of your readers, asthe subject has now been raised. The locomotive fitted, is an i8j<x26in. cylinder, 6 ft. 6 in. wheel, four-coupled in front, type similar to thatillustrated in Sinclairs Development ofthe Locomotive Engine. T. H. M. Slocombe.
