YOUR success in life depends upon the careful thought with which you have planned your career. You cannot succeed unless you give at least is much careful thought to planning your journey through life as you would a fifty mile pleasure jaunt. If you are a young man without a profession or trade, the study of electricity offers you endless opportunity for a successful career. Every new sky-scraper, factory, power-plant, increases the demand for trained electricians. In this age of electric elevators, trolley cars, the third rail systems for subways and elevated roads, the ever present telephone and telegraph, the man who is efficient cannot help but be successful.

The electric light has driven out the lamp and the gas plant, ev*n in the most rural districts. The present day farm house is not complete without its telephone. The big railway sytems are substituting electricity for steam, even over long distances. The inter-urban trolley service is developing to such an extent that sleeping cars and diners are now a regular feature on many lines. A. fortune awaits the man who perfects a storage battery for automobiles which will run a car 100 to 150 miles without recharging. Under these circumstances, with such opportunities open before you, do you think that you can make any mistake by devoting a few hours a day to the study of electricity?
