LYON MANUFACTURING cos
LIGHTNING CONDUCTORS,
OTIS PATENT.
THE ONLY SURE PROTECTION.

From. Hon. HoRAcE MANN, L. L. D., President
Of .4ntioch College.
l would respectfully recommend to the public
the use of ..Ots's Patent Lightning Conductors, :"
for the following reasons:
lst The rod is large and SQUARE, and
square rod, by presenting more surface, becomes
better conductor of electricity than an equal
weight,o the same metal IN round form.
2nd. 1t is continuous rod. Every point oil
junction between the links of chain rod presents
a break, and every break is obstruction to the
free passage of electricity. The lightning has to
get off from one link to the next at the ex-
pense of some delay and circuitousness; and,
whenever such delay and circuitousness occur,
the question is always presented to It, whether it
will 60 to the next link, or go somewhere else.-
Tits better that this question should never De
raised. The longer the links the less danger of
divergence it is true; but where there is any link
there is some danger.
3rd Otis's method introduces glass insulator
between the rod and the house or other body to
be protected. The old method of fastening the
rod to the house or other body to be protected
by iron staple is direct invitation. or rather
a direct command to the lightning to come in; and
when 1t does come in we all know what liberties
it takes. Instead of thus welcoming and order
ing the lightning to enter, and setting conductor
there to show it the way in, Otss rod has lateral
points projecting outwards, and these points make
it more natural and easy for the lightning to 60
from the house than towards it. If the rod be
overcharged. these points take part of the bur-
den and direct it away from, not into the house.
Electricity, indeed, is valuable. is indispensable,
IN all our dwellings, but not in the form Of bolts.
4th. Otis's rod is iron, and IRON is far less fu-
sible than copper. Copper meIts at 1896 deg.
Fsrenheit, wrought iron at 2786, and cast iron al
3479 deg.
For the above reasons, if my recommendation
be OF any avail, should feel as though were
doing something to save the life and property oil
my fellow men. Horace MANN.
