Messrs. Nancy Il Shaifer-Gents I 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 prin-
ciples, it is worse than useless passed 6uild-
IN the ctv, this morning cODersd Nth lightning
rods tohich are, an eUery ,odv calculated to tear
that building to pieces. The rods are toisted and
attempted 70 be insulated by fe,0 inches Of glass

| Your plan ofmaking lightning rodsi is certain
/ ~ by far the best have seen or read of. The
| large surface it affords for the fluid TO accumu

the sections Of the tube-the placing Of the lines
against the building, and the material "copper"
of which it is composed. being an infinitely bet

| which recommend Halls lightning rod above all
Others hitherto invented. No objection can be

| ney & Shailer-Gents In former days gave a
great deal of attention TO Lightning Rods as a
| means Of protection for buildings. HALLS Cop
| per Scroll Lightning Rod. now bsfOre me, is bet
| ter than the common iron just in proportion as
| copper is q 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 Sirteen 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 / would also value
this rod greatly above the iron by reason of its
| Misunderstanding therefor so much less liable to
get loose from its fsstenings than the heavy
IRON rods IN common use. G. ID. ELLIOTT,
