A New Telephone.
According to the claims of an English
Inventor, he has produced a talking
apparatus which will entirely super
cede anything yet produced by Bell or
Edison. His machine talks right out.

through it will not have to be contin-
ually shouting: whats that? I don't
hear you. Stand a little farther from
the telephone, please. That's BETTER"
and other like Interruptions to the easy
low OF conversation. The new talking
apparatus says all it has to say in a
tone loud enough for all in the room
to hear, and without the aid of an ear
receiver. All the recipient of a mes
sage will have to do will be to sit at his
desk and listen, while he holds in his
hand q transmitter into which he
speaks his replies to the person at tho
other end of the wire who is conversing
with him.
The invention is not so much an i'm

bring it's resistance down to the lowest
possible point. Under the plan adopted
the Induction coil has been discarded
all together, and the transmitter and
receiver are directly connected in cir

separate lines, having Il common return

Why Oil Stills the Waves. u
A great deal has been written about
the influence of oil on waves at sea.
and of the practical useful action Of
oil in many cases there is abundant
testimony, but little has been heard Of
the reason for tho results obtained.

nhnts made in shallow water. broken
& water on the coast where the wind and
tide conflicted, that little or no adv:l11-
