sixty feet in diameter. The atmosphere included
within this space is less surcharged with clec!ri
city than that which surrounds il. Hence The
fluid from a neighboring cloud must first fill
up this vacancy, and CT, ate an equilibrium with
the surrounding atmosphere, before 1t can pro-
coed further. Thus the severity OF the stroke Is
consumed and exhausted, and the BALANCE, II
any, is carried to the earth, without the slightest
danger of leaving the conductor. barn filled
with hay or grain is very liable TO be struck,
because the quantity of electricity that will nst-
ural,y accumulate and force its way through the
roof, will form n conductor frequently one hun.
died feet in height. Now if the electric stroke
comes in contact with the electricity thus gene
rated, it will be conducted at once to tine place
at which the latter has bean foImed. II
the contents of the barn were on the
ground, the danger would not be so great,
because the earth would absorb the greater por-
ton of the electricity, which it can not do when
insulated by the floor. The advantage Of hav-
ing one of my rods attached to barn under
such circumstances is, that il receives the elec-
tricity as it is generated. aud carries it to the
earth thus preventing it from forming itself into
a conductor, and putting to hazard the building
and the crops of a whole season, by inviting a
stroke from every passing cloud.

peat that have no travelling sgents. There are
but four persons in this State who are authorized
to act as my agents in selling and putting up
rods; their range of operations is limited to a
district not exceeding one hundred miles from
their place of residence, and they have certificates
Of aeency from me. The right to use the elec-
tro- magnet in the construction of lightning rods
belongs solely TO myself; and any person detect
ed in infringing on it will be punished to the
full extent of the law.
The subscriber having (as before stately put
up near six thousand rods, and never having
heard of loss by lightning in any building
10 which one OF his rods has been attached, feels
great confidence in urging their superiority to
any Others in use. He pledges himself to restore
TO any one the amount paid for the rod il loss is

value and efficacy of his rods is needed tn n is
found in the large number which haze been put

demand for them. For the satisfaction OF others,
