February, 1919 THE MARINE REVIEW : 21 _Suininauwuveaa || We were out of port | three days— the {Chiet Engineer was telling the story, “‘when I realized we were about a hundred knots further along on our course than we ought normally to be, wind, sea and draft considered. As I had been shipmates with the old girl going on four years, I thought I knew all her tricks—but here she was doing a mile an hour better : than I’d ever known her to do. It took me a long minute to figure out what had happened,—then I kicked 7 a myself for being unprepared when it occurred though I was responsible for it and knew beforehand it was coming. | ‘‘Just then the voice-tube whistle blew, and the Captain called in to ask if I had a date on the other side. ‘No’, said I. ‘Just getting injtrim to get away from the subs’. ‘More power to you’, said he, ‘but it’s a rev- elation to see this vessel exceeding her best previous performance, and I am curious to know the answer’. So I told him, ‘Diamond Soot Blowers’. “And it was Diamond Soot Blowers. We had put them on in port. You had only to step into the firehold to see the difference. The boilers were steam- ing easier than they had ever steamed before and the firemen and coal passers were having an easier time of it. It was good to see the pride they took in their new equipment. “‘Well sir, we finished that trip in eighteen hours less time than we had ever made it before, and burning 5% less fuel. Maybe, you think the Fleet Engineer and the Old Man didn’t sit up and take notice when the trip log reached them.” This engineer’s experience has been duplicated on hundreds of steam-ships. There is a Diamond Soot Blower for every type of marine boiler. | For full information write for Bulletin 122, “How Some Ship-Owners Have Increased Their Profits.” DIAMOND POWER SPECIALTY COMPANY Detroit, Michigan eet Be Ss pic PASO ee
