12. one dynamo (Edison, No. 6, current 200 amperes, 115 volts), showed a horse-power of 174. The various indicator-cards show 1146. 6 as the total plant horse-power: that developed by the boilers, 1268; loss by radiation and condensation, 121. 4. Considering the distance and the multiplic- ity of pipes, this is not excessive, and is due to careful steam covering and other appliances for preventing radiation. The horse-power lost by radiation could 78 LEAD-SMELTING. possibly be placed at $1300 a... year; exclusive of labor and including only the net coal loss. Attention has often been directed to the impor- tance of a union of all the exhaust steam about in- dustrial plants by the use of a central condenser. It would be well to make frequent tests of all boilers for efficiency. In the use of both modern water-tube and old-fashion tubular boilers a series of tests demonstrated that the latter, when properly made and set, was 27 per cent, more efficient. TOOLS AND IMPLEMENTS. Provide each furnace with a large anvil.
