The theory and practice of jute spinning; being a complete description of the machines used in the preparation and spinning of jute yarns .. . r cams. The furnace bars moving at the sametime, the coals are carried at the speed required into the furnace. Agreat many stokers of different construction are now at work, eachhaving their own so-called special advantages. An illustration of astoker by T. & T. Vicars is given. When working with furnace stok-ing apparatus it does not tend to economy to force the consumption ofcoal, as it leads to unnecessary waste of fuel, but you can consumefrom 21/22 tons of coal in a working week of 56 hours without over-driving the apparatus, and if a fair quality of Scotch coal is used thewaste will not be more than 4/5%. This stoker has been a long timebefore the public. The illustration is given here to show the principle THE BOILERS AND ENGINES. upon which the machine works. It is not necessary to commenthere upon its comparative merits with other furnace apparatus atpresent in use. VICARS NEW & IMPROVED PATENT MECHANICAL STOKER AND SELF-CLINKERING SMOKELESS or THE BOILERS AND ENGINES. The boilers should be cleaned internally, if the water is of a fairquality, three times a year, and the flues once a year, and the brick-work examined carefully after the annual cleaning is done. Theeconomiser should be blown through once a day, and the soot-chamber and side flues cleaned out three times a year. If thewater is of a fair quality, the pipes will not require to be cleanedinternally more than once in ten years. To get the full benefit of the advantages of the economiser, theboilers should be continually taking water. If the feed valves arenot kept open continuously, many of the advantages of the econo-miser are lost. Care should also be taken to notice that the pressureupon feed water should not be more than 10 lbs. per square inchabove the pressure to be carried into the boilers. If more pressureis used, it causes
