Ihave a case before me upon which I wouldbe pleased to have your opinion. A loco-motive boiler, which is seventeen yearsold and has been in constant service, wasconstructed to carry 135 pounds workingpressure. The firebox was renewed sevenyears ago. the boiler continuing to carrysame pressure; 15-16 crown stays, 4^ x4/2-inch centers. About twenty monthsago the engine was fired up in roundhousewith low water crown sheet, and flue sheetand side sheets were heated to a cherryred down as low as the eighth row offlues. The boiler was filled up with coldwater at once, not waiting for sheets tocool. The firebox had no work done on itin consequence of this heating, except todrive up heads of stays, so they would notleak. The crown stays have given con-siderable trouble from leaking ever since. Eight months ago the engine boiler wasgiven a hydraulic test of 180 pounds andworking pressure raised to 160 FLOUDS 0.\ ENGLISH (1) Do you think this boiler was safewith the increased pressure of 160 pounds,an increase of 25 pounds? (2) Was the test of 180 pounds hy-draulic pressure sufficient? (3) What effect would this heating andsudden cooling of sheets and stays haveon them as to their strength and durabil-ity? to add to the embarrassment of beingshort of power they have to contendfor a period of six or eight weeks withthe disadvantage of leaky flues. There isapparently no cause for the flues to con-tribute to the embarrassment, as the fire-men exercise the most exacting care in theperformance of their part without accom-plishing the desired result. January, 1901. LOCOMOTIVE ENGINEERING 13 The writer has observed for the pastthree or four years that the flues give themost annoyance during the fall rain-storms. Those conditions may be attrib-uted to the chemical substance leachedf
