The Gucs.ior of the durability of lie lamp Is u
fundamental one in incandescent lighting, ana IN
tis resDect Mr. Edison cla;l5 to have achieved re-
snits f,r beyond all others. The company claims
nm average life of GOO hours If the normal lnteh-
sity of sixteen candles is not exceeded the Edison
lamp should in ordinary domestic use last from one
to two years III the present state OF the arr OF manu-
facture The number of lamps TO he maintained
per horse power is another important lecture

sitiOn after IA thorough test of all the lncanueS-
cent lamps present, gave a verdict III faVOrOl thVsc

The manufacture of ths dynamo machines and
engines ior working tho same is controlled Dy "a
company having works at No lO4 Goerck-st', Sew-
York aud the energy with which this part OF the
enterprise is conducted may be appreciated when II
is stated that within three weeks alter
the shops were rented the first Edison
steam DYNAMO, capable of supplying over
GiVt1 -canllp lights.
Until recently 800 skilled mechanics were en-
plOycd, but the business has so increased that ?oO
additional men have been taken thus increasing
the payroll to 500 Still more men are needed, but
il has been found difficult task TO select competent
men for the work Not less than l,ooo uleh n!Se
been specially trained at these works since the
start, special and careful training being OF aD-
soue necessity. Since the tlmr OF testing tne IsI
steam dynamo, eight Others oi Sill larger size l,foo
lights have been completed, and work on Twelve
others Of ne same size commenced. ana during the
last twelve months $50 dynamo machines Oh lesser
capacity, varying from TO 250 lights So put chiev
for go full lights each aggregating 1o,OoO ghts III
all, have been turned out. r
There is another enterprise conducted OUTSIDE OF
the Edison Light Company, but stu under me
auspices of Mr. Edison, namely, the manu- acture OF
the underground conductors and their accessories.
The iron ubes junction boxes, conductors, etc. are
made by outside concerns, but the functions Oh ne
Electric Tube Company" are u insert tne mains III
the tubes hll the latter with the insulating COM
pound, test each length rs completed, ana, Ilhdliy
with the aid of its corps OF trained men, 10 lay the
III the streets ana make lnc proper uouSc Ool
nccuons. This company was formed In june 1851,
and started ITS business at No. 10 WaSnugtoh-st.,
where it is at present continued. From the com
mencemeut of the work up TO the present time, Ie
company has made l45, 500 feet of street mains ana
feeders, of which 97.2l0 have been sold and de,
lIyered. The greatest number OF WOrhmcn en- gloyeu
at any time by the tube company was lOJ. III now
employs tfty-One, and has a capacity lor turning
out 900 ieet of street mains per day at the present
time, and "A prospective capacity OF tnrnlng OUT
. 800 feet per day, with the necessary boxes JOINTS

The last branch of the Edison light system is the
manufac urc of the lamps, which Is controlled also
by separate company, The EdlsOn Lamp Com
pany' which commenced operations on November
II, 1880 On the Isl OF April. loS2, the factory
was removed to East Newark, IN order to secure
larger and more convenient buildings Al TINS
manufactOTy 100 hands are now employed ne
tools and power in the mandatory are ade-

THE FULLER ELECTRICAL COMPANY.
Mr. j. Il. Fuller, of Brooklyn, n. Y, was one of
the first in this country to undertake the perfection
of dynamo-electric generators and early turned his
attention TO the development of electricity for pur-
poses of electric plating and the operations OF tele
,,raphic circuits During the last two years of his
life he devoted himself cnicly to perfecting ap-
pliances for u complete system OF electric lighting,
and organized the company which bears his name,
in connection with several capitalists in Oc-
tOber, 1873. The work Of Mr.. Fuller was continued
by his assistant, Mr.. James }. Wood, who has per-
fected the apparatus and extended the inventions
to degree of usefulness, winch probably Mr. Fuller
himself never considered possible. This company
confines its operations 10 the light and manu-
factures electric generators OF various dimensions,
from one light TO thirty, all on one uniform plan
These machines are 50 constructed as TO supply the
greatest atalnabc electric force in proportion 20 the
material employed. This cOmpany's lamps are OF
three kinls-singlc, duplex and focusing. The
single lamp consists Of a hollow suspendiug tube
a cylinder containing the apparatus for regulating
the movement of the positive carbon pencils, the
frame betw. en- the sile bars of which the car
bong points are placed, and the bottom
plate. which contains the negative carbon
holders. The caTbOns burn from seven 70 eight
hours The duplex IL n modification of the single
lamp having two sets of carbons changing the eiec-
ire current automatically ron one 10 the oInel
when required. These lamps are convenient wher
a light is required all night and can be used slngly

running these ghts is sail To be threc-quarters Of
a horse power for iIht of 1000 candle power, fOI
generations Of ten light capacity anl upward, and
