NASHVILLE, TENN, July 5. 1869. Messrs.
Nancy j Shaifer-Gents l have carefully ex-
amiued into the merits Of the Lightning Con-
ductor which you propose TO introduce 10 THIS
community. lhe material Is the very best, and
the construction and mode of putting up, in ac-
cordsnce with the views of the most disiio-
guishsd electricians who have, In recent years,
devoted time anu attention 10 thlS iuPOIlAht
practical subject.
Ii ali contracts made by you are faithfully
executed, land of this all who know you Will be
perfectly sure any one who uses the Copper
Scroll Lightning Rod may feel quite secure
even amid the roar Of the terrlhc thunder
storms SO frequent and so fatal in our region OF
country. Wishing you every success, yours
truly, ). BERhlEN LlNDSLEl.

Mssr. S Nancy Sb sdS sny believe
that much of the popular want of faith
in the protection of Lightning Rods Is
TO be traced 10 an imperfect construc-
tion of the rods themselves. Unless one be
made strictly in accordance with scientific prin-
ciples ii is worse than useless. IpdsseG a buitd-

Your plan OF liking lightning rods is certain
Iy by far the best have seen or read of. The
large surface it affords for the 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 il is composed, being an infinitely bet
ter conductor than iron. are the chief points
which recommend Halls lightning rod above all
others hitherto invented No objection can be
fairly brought against H. and ats protection TO q
building IS calculated to oufLiUe the existence o'
any ordinary building ITSELF Very truly yours.

NASHVILLE, Tenn, July 5. 1S69-Messrs. Ma
uey & Shaifer-Gents: In former days gave a
great deal of attention 90 Lightning Rods as 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
copper is better conductor than iron. and al
so in proportion to the greater surface which
it offers.
Taking into account the greater surface and
the superior conducting power of copper, One
of Halls Rods is equal in conducting power to
about iSirteeR 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 is
the one approved by Science and proven by ex-
perience TO be the safest. l would also value
this rod greatly above the iron by reason Of its
hghtness-being therefor so much less liable to
get loose from its fastenings than the heavy
iron rods liz common use. c. ID. ELLIOTT,
