In my opening letterJI spoke OF thu
incandescent light as perfect for the pur
pose OF interior illumination: A simple
i filament ofslight, glowing in vacuo,dt II

I Watching in my minds eye the pro
gress OF the electric light, the ever
recurring contretemps to which investi
gators were subjected as viewed in the
! light of the present day are simply anus
ing. Breaks in wire insulation, difficulty
! in adjusting the battery power to the
needed force, inability to preserve the
correct adjustment OF carbon points, pro-
| voking intervals of total darkness alter
mating with short periods of brilliant
light, difficulty ever recurring, all-per-
vading, seemed to be the heritage of the
seeker after light. es ioc H. ssga5
/ Now, the induction of electric currents
and, the collection and storage of the
force are matters Of ease and certainty.
It's value as an illuminant in relation to
other standard lights is ascertained, its
Volume can be measured, and the force
itself can be, accumulated in portable
storage batteries, and transported from
place to place with very small percent
age of loss; ), dwellings may be lighted
from basement to attic by simply con-
Meeting the wires with. portable &C.
cumulator, turning switch, or pushing
a button, and the operation is complete.
Every light may be under seperate con-
troll, and the volume of light in any lamp
may be increased or diminished with as
much facility as if gas were the illumina-
ting agent. The device which renders all
this possible is the dynamo machine.
The foundation principle of the dynamo
was discovered by Farady as early as the
year 1881, and forty-six years later is the
date of Brush's first patent for the most
popular dynamo at present known to us.
VI In the early days of electrical expert
mental research, the electric fluid or
force was generated by the ordinary Vol |
taic battery, consisting of two plates OF !
zinc and copper partially plunged in q |
bath of calculated water, wire being !
connected with each plate, and the union /
Of the two wires forming circuit. Butt |
was evident from the beginning that in
order to obtain a sufficient volume of
electric energy or force for the purpose of
Illumination some other means must be
devised for its production, more constant
n result than ordinary chemical action,
md at greatly lessened cost in order to
make it commercially available. 1 have
stated that Prof. Farady laid the founda-
ion on which all dynamos are con-
tructed, and his dicovery simply was,
hat when permanent magnet is placed !.
n close proximity to coil of copper
wire, and either the magnet or the coil is
made to reyolve at high velocity a cur
ent Of electricity is induced and follow
ng up this important result machines i
7ere constructed called dynamos, for the
urpose of generating the electric energy.
he electric energy so induced is collected
y various devices, and is either con-
ucted into immediate service, or is i
lrned into the storage battery and laid Z.
p for future use. The Brush. dynamo
hen in operation is a4sight well worth t
icing by any person interested in me-
hanical or scientific matters. The heavy
astings and bright metal work, the light
flashing, dancing-the steady
cadence of the machine, pro-
aiming to the educated ear the perfec-
on OF mechanical adjustment, are apt to
ave mental impression Of enhancing
1canniness. Such is the, dynamo or =
,nerator. l have said that the electric 4
lid may either be conducted to the o.
mps direct or be carried to storage b
Ittery, and there kept for future use. A e
Try cursory examination of the subject r
sufficient to show that incandescent
,htlng direct from the dynamo has SER &C
US disadvantages, such as irregularity II
pressure or total cessation OF light, ty
lenever either from accident or neces-
y the dynamo was at rest, and as in =
ndescence is the light of our homes and
aces of business and assembly, the
ance OF being left in darkness without :.
sslblllty OF avoidance would be fatal to IN
claims as practical illumination.
In this dilemma the iaccumulator or Il
rage battery comes into playa box

d in an calculated bath. When the FL
