country the residents of the villages
and country places will enjoy the lllu-
mination. The beams of the search
lights on the Electric Tower may be
cast far up Lake Erie to give greeting
to the heavily laden boats that will en-
ter Buffalo's harbor, or they may be d.
rected out to East Aurora to bring Ell
bert Hubbard and his Roycroft shop
under searchlight inspection, their bril-
liancy carrying a message that will
compete with the famous message to
Garcia for public recognition.
While these searchlights will be
pleasant to lock upon and watch, they
will also carry with them education and
knowledge to all who seek to learn. In
all the papers of the locality within d
radius of rs or 100 miles the Morse and
Meyer alphabets may be published in
order that the public may become ia
miliar with them, and then there will
be much pleasure in taking or receiving
the announcements which may be made
by the searchlight flashes. In the army
both the Meyer and the Morse alpha
bets are used, while the navy confines
itself to the Meyer entirely. The Meyer
code is usually carried out by means of
a flag moved to and fro, right and left,
starting from the center. 1t is evident
that a beam of light cast by a search
light can be utilized in the same man
ner, a combination of movements
making letters. 1t is known that the
commanding officer Of the Fourth bril-
gade, national guard, state of New
the opportunity presented by the Pan
American searchlights for conducting
signal operations, and the officers may
avail themselves of these facilities to
obtain practice in the transmission of
signals and messages, while at the
same time they may gain much expe-
rience and information as to the dis
tances such signals can be transmitted.
A valuable feature of the searchlights
in connection with the Exposition will
be that they can be used to illuminate
details of sculpture in and about the
grounds, while their rays may be con
centrated at any spot desired in the
grounds during unusua and special oc-
casions.
The projectors to be used on the
Electric Tower of the Pan-American
grounds as well as the one to be in
stalled on the Observation Tower at
Niagara Falls will be of the General
Electric company make. They will be
of the latest design and will combine
all the very latest Improvements. In
general appearance they will be com
pact and graceful, but built to with
stand more than ordinary hard usage.
Their simplicity of construction, eff
cheney of operation and durability of
service will be very pronounced. They
will be fitted with the Margin ground
glass silver plated mirrors, which type
of mirror has two spherical surfaces of
different radii, and the reflection and
refraction of the glass will cause the
rays of light to be projected in parallel
beams when the arc is in focus. The
lamps of a searchlight are designed to
throw the greatest possible amount of
1inb+ ON tho 1,aHaator md Soraon ch1rt-
tiers are provided to prevent the direct
rays from leaving the protector, so
that all the rays of light are reflected
and sent out parallel. The 80 inch pro-
%jectors consume so amperes of current
with from 40 to SO volts at the arc. The
searchlights to be used in the display
in question will be hand operated. so
the bea moi light a be trained verti-
cslly or horizontally by the operator,
who will stand close beside the pro-
jector and move the barrel in any di-
rection ne may desire. In the case of
electrically controlled projectors the
apparatus may be operated at a dis
lance. This is accomplished by having
electric motors mounted in The base OF
the protector, one motor operating a
train of gears controlling the vertical
movement and the other motor operat-
ing another train of gears controlling
the horizontal movement of the pro-
jector. The movement of the beam OF
light corresponds TO the movement of
the handle of the controller, and bo b
horizontal and vertical movement can
be obtained at the same time. When
the handle OF the controller is released.
it is brought back by a powerful spring
to the neutral position. 1t is worthy of
note that all projectors are very accu-
rately balanced and that when it is de-
sired to have a beam of light covering
a wide area a front or divergent door
made up of strips Of glass ground piano
convex, each strip being a lens, with
the convex side outward, is placed in
position, which DIVORCES the beam. but
does not increase its height.
There is no doubt that visitors to the
Pan-American Exposition will gain a
