Mons. Emile Provost, French electrician,
who has been in this country time with view OF
introducing application OF electricity as motive
power, extended invitation to few gentlemen on
Saturday to witness the performance OF his machine
Unfortunately previous to the hour named very heavy
current of electricity from the battery through
the main magnet, which had the effect TO either over
heat or the smaller magnets. SO that tho machine
would not operate properly. 1t has been running during
the past forty days and nights at cost of ten cents each
