Comparing results in August,1902, with those of August, 1904: Raw water havingbeen used during the former, and treated water duringthe latter period. a. Number of trains given up on the road on accountof leaking boilers during August, 1902, was 27, whilethe number given up for the same cause in August, 1904,was two. b. Number of trains that had to reduce the loading,by setting off cars, on account of boilers leaking, during. Fig. 1. August, 1902, was 13—while for August, 1904, noneneeded to do this. c. Number of through trains, during August, 1902,with delays of one hour or more, that had locomotiveschanged at McKees Rocks on account of boiler leaking,was 31; while the corresponding number for August,1904, was only three. Similar comparisons can be made from results alreadyattained which show enormous advantages in favor ofusing purified water, in the increased life of flues, andof fireboxes, etc., and in the reduction of boiler-makerswages—in the increased service obtained from the loco-motives and the reduction of fuel necessary on accountof the removal of scale. By use of the plant here described—locomotives re-quiring a change of water, have their fires cleaned inusual way and are sent to roundhouse preferably withfires banked and steam pressure at about 100 to 125 cocks have been placed in the left side of the November, 1904.
