"If you w:intto know whit the m st intcif stui ill (ho ic cut electrical inve.i-lions inve.i-lions is tlu must interesting l naval men, that is," said a naval el'icer the ot.ier o'av, "you will find it in i tie dynamo dyna-mo governor. The ordinary run i f people peo-ple did not tliinh alvMit this point, of course, but when Edison's works down town in New York burned cut because the load on the dynamos was suddenly lightened ai.d the whole power of the machines was tinned loose on the lamps that remained, theie was not a naval officer but st pped to think what would happen on a watship should such an accident ac-cident occur there. Under the ordinary method of controlling cctrical systems the ei.g.neer has to stand by to manipulate manipu-late what is called a lesistence box whenever the load at the dynamo is suddenly increased or diminished by adding to, oi cutting i ff the number of lamp. It this box is attended to instant ly m.itteis arc ali rght- but in a warship war-ship in time of battle it might very easily easi-ly happen that an unlucky shot from the enemy would not only cut off all but a lew of the lamps, Ui also kill the engineer, engin-eer, whose dutv it was to handle the resistance re-sistance box. Or the lamps might be cut oil . inl the engineer be too badly frightened to do the iij;!ii thing. In a moment the remaining limps on the ship would be desirojed, ami the dynamo dyna-mo as well. The magazine would be in utitr d.ukucss, nud iatal confusion Wuiild prevail. The one tiling for which naval men have looked was a governor for tin dynamo.

"There is another feature of this governor gov-ernor that makes it valuable to a warship war-ship whose coal space is limited. When tue lampj are cat off the power of the dynamo and the consequent consumption consump-tion ol coal ate not wasted in forcing the I current through a resistance box. The ! reduction in ths power used is almost in proportion to the load lemoved or the the number of lamps cut off. If soolamps, lor instance, require 50 horse power, the power requited when 450 lamps were cut oft' would be, say, 7 horse power, which means a saving ot the coal requited requit-ed for the 43 horse powerdispensed with. "The invention is not of the sort to attract notoriety outside of people interested inter-ested in electrical plants, but to naval vessels it is a matter of enough importance impor-tance to remove the only objection against dynamos on shipboard."
