ue of Canadian Foundry-man. From this it will be seen that Canada isfavored with abundant water power and asthis is only one of our many falls and noteven our greatest it will be seen that elec-tricity is to play a prominent part in Can-adas development. While this is our great-est one at present developed the St. Lawrenceis offering something which is said to be offar greater magnitude. The water afterleaving the Niagara river has yet to fall256 feet before getting to the Atlantic.This coupled with the water from theOttawa and other rivers is said to be morepowerful than the Niagara. It must not be supposed that electricitydepends on water power, as steam or gas isequally as efficient but where fuel is hard toget and water power is plenty the water is tobe preferred. Whatever power is used thedynamo or generator as it is sometimes calledgenerates the electricity. In the illustration, Fig. 1, will be seen thefundamental principles of a generator. The motor, as we have already seen, is

Here it falls 158 feet and has a widthof approximately two thousand feet. Need-less to say its white color has disappeared bythis time. The water is so deep that it re-tains its green color for some distance below similar to this but runs in the opposite direc-tion when connected to the generator.The generator may be stationed in the engineroom of the plant or it may be at NiagaraFalls or anywhere else, and if we want touse the power to drive the foundry blower 20 C A N A DIAN FOUNDRYMA N Volume XII we place the motor wherever we wish tohave the blower located, and connect it tothe generator by means of wires. Two wiresare always required, as electricity will onlytravel where there is a circuit. If the circuitis broken the electricity ceases to travel.It will be seen from this that one wire mayremain connected
