down the other, twisting the wire round
and round like wooden thread and close
up to what will be the underslde of the
coin. Pass the end of this double wire
through the hole in the wet skin. lay the
disc box across two stools, benches or
tables. and to the hanging wire fasten a
weight of twenty-five to thirty pounds.
The object of this is to stretch the skin, so
that wnen the board is put against the wall
the disc shall be cOncave. But do not take
off the weight till the skin is perfectly dry
then its strained position will become fixed.
A hole must now be cut through the wall
in whatever part Of the house is most con-
Venient for the purpose. The hole should
be round and about three inches in diane
ter. The box is next placed against the
wall ana the wire attached to the button or
| punctured copper inserted through the hole
where it is ready to be attached to the main
wire. The board should be fixed to the
| wall with staples, screws or long nails, but
the thing is not difficult. OF course when
| the bulged out skin of the disc is pulled out
! wards, later on by the strain OF the con-
Meeting wire, it must not touch the wall,
but the point should be directly opposite
the hole.
We are now ready to begin the work OF
wire stretching and the next step is to pre-
! pare as many insulators as shall be needed
! along the route of the wire. IL it must take
a crooked course passing house corners,
trees, telegraph poles or any other oossruc-
ton it will be necessary to ay 1t by guys
so as to keep its path clear. The lnsulators
are not made Of glass as might be supposed,
! but are constructed of any clos Ny twisted
or braided cord silver lake cord, or rope,
3-i6-inch in diameter being est. The in
sulator cord ought to he 4 or inches lo7g,
and this must be made into loop, the ends
to be secured by fine copper wire wound
tightly around the ends of the cord so that
the insulator may not come apart.
Now take the end Of the coil Of wire which
should be lying on the ground below and
slip it through as many OF the insulating
loops as may be needed for the whole way
and NAV add it is mucl better to string
too many than too few insulatOrs on your
line. for YOU can easily sulp of all tat are
! unnecessary when your telephone connec-
tion is conpete. While it ie necessary that
the line should be firmly held in its place &c
that the WIRE NAV not toGch any other BODY
it must be kept in mind that TOO many lnsu'
lating loops hanging from the wire de1dens
it somewhat by checking tne Vlo' a.iol
which is the medium by which che sound is
sent thrilling along. 1t is NOT yet deter
mined by science whether electricity ha'
ANYTHING TO DO with the transmission OF
sound along such line as this, Dus oeIlevt
that it has.
The direction that the wire is to tak'
sbould be carefully determined before YOU
peqin to string it. If it has to run through
nerhborhood where there are many
houses /: is best to guy it to any trees that
are available, or it might now ana again DS

not to use the regular telegraph pole al

vour neighbor to fasten your line to SOM

select the highest tree and fasten IL wen up
for there il will be out of the way OF ms

be necessary when stringing.
A word about guying: The guy Is

part Of the loop shall press tightly agalns
