NASHVILLE, Tenn, July 5. 1869. - Messrs

amined into the merits of the Lightning Con
ductOr which you propose TO introduce TO this
community. The material is the very best. and
the construction and mode of putting up, in ac-
cOrdance with the views of the most distiu-

devoted time and attention to this important
practical subject.
If all contracts made by you are faithfully
executed, (and of this all who know you will be
perfectly sure any one who uses the Copper

Messrs Maneg x Shailer-Gents. | believe
that much of the popular want of faith
in the protection Of lightning Rods Is
to be traced to an imperfect construc-
ton of the rods themselves. Unless one be
made strictly in accordance with scientific pTin-
ciples it is worse than useless. passed a build

Your plan ofmaking lightning rods is certain
ly by far the best have seen OF read Of. The
large surface it affords for She fluid to accumu-
late on-the security of the method Of uniting
the sections of the tube-the placing Of the lines
against the building, and the material "copper"
of which 1t IS composed. being an INFINITELY bet

which recommend Halls lightning rod above all
others hitherto invented, No objection can be

NASHVILLE. TRNN., July 5. 1S69-Messrs. Ma
ney X Shaiter-Gents: In former days | gave n
great deal of attention to Lightning Rods rs a
means of protection for buildings. Halls Cop
per Scroll Lightning Rod. now before me, is bet
ter than the common iron Just IN proportion as
CONFER is n better conductor than iron, and al
so in proportion to the greater surface which
it offers.
pf
of Halls Rods is equal in conducting power to
about S.rtecR of the iron rods commonly used
in this country. The Point in this rod is per-
feet, and the manner of putting up the rod il
the one approved by Science and proven by eX-
perence to be the safest. | would also value
this rod greatlv, above the iron by reason Of its
lightness-being therefor so much less liable to
get loose from its fastenings than the heavy
iron rods in common use. G. ID. ELLIOTT.
