The arrangement of the tubes is such, that the flamesand hot gases of the furnace must take a tortuous courseto reach the flue. This arrangement allows the greatestamount of heat to be transmitted to the water. li^gft^^M^^^^te*^ 531 The circulation of tliis boiler is said to be so rapid that,when worked to its full capacity, the water will stand fromfour to seven inches higher at the front end of the drumthan at the rear end, as shown by glass gauges placed ateach end of the drum. Steam is taken from the rear end,assisting the circulation, and the water descending thecirculating tubes to the rear headers deposits in the muddrum much of its suspended impurities. The method of cleaning is satisfactory, and all togetherthe bciler is one of the best of its class. INTERURBAN CONNECTIONS. THE careful reader of the signs of the times and theS
