be known by mutual consent of the
lighting companies and city author
tiles through the country as lamp
taking $50 watts. The 10 ampere
A. C. lamp, when adjusted for 70 to
IS volts at the arc will consume from
515 to $50 watts so that you will see
that your lamps must then fulfill the
requirements of the 1000 nominal
candle power.
Trusting the above gives you the
information desired, and assuring you

sistance possible in this matter, ] am,

Philadelphia, Pa, May 81. 1910. Mr..
Washington. d. c.
Dear Sir:-In response to your in
quiry of the 26th inst. with reference
to the candle power rating of rs
ampere series enclosed type arc
lamps, beg to advise that the question
of candle power on arc lamps of var
ious wattage consumption has always
been a much discussed point amongst
Illuminating and central station engi-
neers, inasmuch as diffusion and the
angle of distribution have necessarily
to be taken into consideration as
we'll as the color of the light. How
ever, at recent conferences OF the
American Institute of American Elec-
trical Engineers and the National
Electric Light Association. it has been
decided and therefore established
for some years past that rs ampere
series A. c. arc system shall be rated
as a nominal 1000 candle power.
This is considered to hold for any
and all standard makes of arc lamps,
inasmuch as the stress of competi-
ton requires any and all to be of
nearly equal efficiency.
The standard taken for the candle
power rating has been SO ampere
open arc, which ever since its incep-
tion has been recognized as the 1000
candle power and as the energy con-
sumption of the rs ampere wood
system is identical. If not slightly
greater, than that of the SO ampere
open arc; you are therefore furnish
ing the same candle power at diff
ferent angle of distribution from the
arc, but with a better distribution
and general diffusion, l. e., less shad-
ows.
In the event of my not having COW
cred any point which you would care
to have me explain, womld no pioao
me.
Yours very truly,
The Adams-Bagnall Elec. Co. -

Thereupon F. r. Weller, in answer
to interrogatories propounded to him
answered as follows:
Questions by Mr.. Harlow:
Mr.. Harlow: You are the general
manager of the Alexandria Electric
Company?
Mr.. Weller: Yes, sir.
Question: How long have you been
connected with this company?
Answer: About year.
Question: How long have you
been connected with it in the capacity
of general manager?
Answer: For the same period of
time.
Question: Did you ever take up
with Mr. Kirby while he was with the
company the question of arc lamps?
Answer: That was the first ques-
ton we took up. In fact we took
up that question before we bought
the plant.
Question: Did you find out about
it from him?
Answer: Mr.. Kirby on number
of occasions assured me that the
lamps we're all right, and were Z u
ampere lamps. / have made num-
Der of inspection trips around the
city myself and ! found them salts
factory. Mr.. Kirby told me that all
the lamps had " ampere coils in
them. / might state here that / knew
about this question of candle power
lamps, and for that reason we took
particular care to see that the lamps
had been changed to ~ ampere
lamps We were satisfied of that
when we bought the plant.
Question: What system did you in
stall for the purchase of supplies?
Answer: ! have found that in
every plant that / had anything to do
with the greatest loss was in the
purchasing department. All the sup
plies are now bought on requisitiOn
from the Superintendent here in Al
exandria.
Question: When you bought the
plant were you assured by Mr.. Kirby
and by your own investigation that
there we're ~ ampere coils in all
the lamps2
Answer: Yes sir.
Question: Has Mr.. Kirby ever
drawn any requisition on you for
I Y ampere coils?
Answer: No sir, not TO my knowl-
edge; l knew there were some Y
ampere coils on hand; didn't recall
his ever drawing on me for any adj
coils.
Question: Did you ask MIR. Kirby
with regard to the question of coils
only when you first came here?
Answer: / have asked him re-
peatedly, and he always assured me
that the lamps were all right, and
he said that the dissatisfaction did
not amount to anything. AS long
as ne was in our employ he did not
intimate that the lamps were not up
10 the standard.
Question: Has the company ever
been notified that the lamps were not
up TO the standard?
Answer: Absolutely not; we have
never been notified that the service
was not satisfactory; the only notice
NO had UaS tho nofica ra cav in tho
