Stationary steam engines, simple and compound; especially as adapted to light and power plants . ng of journals, but whichshould also be so simple in plan, so inexpensive in construc-tion, and so easy of repair, that the cost of maintenance,that great tax upon the proprietor of the average steam en-gine, should be reduced to the lowest possible figure. In these engines, the possibilities in the direction of in-creasing speeds, are sought to be made the most of. Theirmarket is not only to be found in the domain of the electricalgeneration of light, and electrical transmission of power,but in older fields of work as well. The loss of power inthe jack-shafts, or first motion shafts, of mills andworkshops driven by the low-speed engines is an item ofno inconsiderable amount in many cases. The tendencyis now observable toward the adoption of the high-speedengine, even where not quite as economical in the use ofsteam, in direct connection with the main line of shafting,through the intermediary of a single belt or pair of gears,or even by directly attaching the crank-shaft of the engine. ELECTRIC LIGHTING PLANTS. iig to the main line by a coupling. Many flouring mills andseveral rolling mills to the personal knowledge of theauthor, have been operated in this way for some years, andthe system will probably become rapidly more this country, the use of gearing for such connections haslong been almost entirely superseded by the introduction ofbelting. The smaller first cost, the diminished noise, thelessened danger which accompanies their failure, and otherobvious advantages, have been found to far more thancounterbalance the cost of maintenance of the belt. Bythus connecting directly to the main line, also, the cost ofbelting is greatly reduced. As the speed of shafting israrely less than 150, and seldom more than 250, revolutionsper minute, it is not difficult or objectionable to establishthis method of connection. The same advantages are thenderived that are expe
