about S,oea,eoG a day.
Mr.. Murphy-Do you have in your COM
pany chemists TO examine the constituents
Of the oil that you use before IL IS used2
Mr.. McIlhenny-oh, yes.
Mr. MBTphy-You have that analyzed?
MT. McIIhenRy-Oh. yes; that Is cheni-
cally examined. We have large amount
invested here in tanks and pipe lines.
Mr. Sims-Changing to coal gas would
not disturb your pipe lines?
Mr. McIlhenny-There would be no use
for them afterward.
Mr.. Sims-I mean the mains throughout
the city?
Mr. McIlhenny-No. But these oil pipes
running from one works to the other.
Mr.. Sims-Would you not need oil in
making coal gas?
Mr. McIlhenny-No
Mr. Sims-coaI gas Of p candle power2
Mr. MeIlhenny-No: unless you are COM
PEELED 10 make y OF q candles
Mr.. Sinls-I said making p candle power
you would need oil?
Mr.. McIlhenny-Oh. yes; and that was
done here for a long tine.
Mr.. Sims-Then the pipes would be en-
tirely abandOned2
AIr. McIlhenny-It Is a very expensive
way OF doing it. and il is not satisfac-
tory way, because there is no way Of TX
ing the oil
Mr. SiEs-In making 22-candls power
water gas. or making 22-candle power
coal gas. as you would have 10 do, which
is the more expensive to manufacture?
Mr.. McIIhenny-I think the coal gas,
raised 10 that candle power. would cost
more than Il does 70 make water gas.
Mr.. Sims-Could il be furnished as
cheaply TO the consumer?
Mr.. McIIhenny-COal IS going up
Mr.. Sims-Could it not be furnished as
cheaply 10 the consumer-z2-candiep power
coal gas brought Up by OLE
MI McIlhenny-No; not quite. But IS
candle power coal gas could be furnished
cheaper. probably, but 2 could not De-
cause that would involve the purchasing
and handling Of a large quantity OF oil.
Mr. SiIns-A few moments ago a gentle
man, MI Love, stated that It took about
one gallon for a gallon and a half Of oil
per 1000 feet TO enrich coal gas. when Il
takes about six gallons TO enrich water
gas.
Mr. McIlhenny-Thet is correct
Mr.. Sims-So IL takes more oil with
water than il does with cOal2
Mr.. McIlhenny-Oh. yes. In the first
place. you commence coal gas with Is
candle gas, and with blue gas you have
no illuminatin whatever.
Mr.. Sims-You supply Il al with oil?
Mr.. Mcilhenny-We supply Il al with
oil
AIr. Slms-Then with coal gas the con-
sumption OF oil would be less. II I IN
derstand you. 10 make p candle power
per I.0o feet2
Mr.. McIIhenny-Yes- II would depend
On the character OF the coal. probably
between one and two gallons
MT. SiEas-But you would have 20 have
more coal per 100 feet than you now
have?
Mr.. McIlhenny-Oh. yes.
Mr.. Evan II. TuckeT-Mr. NcIlhenny,
understood you 10 say that the citizens
OF Washington were not satisfied with
the 16-csndle gas Did you mean by that
that they were not satisfied prior TO this
present act Of 1852
Mr. McIlhenny-Yes- no, not 1885
twenty-four years ago, when We made
nothing but coal gas.
Mr.. Tucker-The law prior 20 this pres
ent law provided for a ls-candIe power
gas. but you remember that that was
/ BY q different test from the test now
/ employed. The old test
/ Mr.. Taylor-Now. Mr.. Tucker. Il this /:
q statement
Mr.. Tucker-This IS a question. He
I knows all about this law.
/ Mr.. Taylor-Proceed with the Law
/ Mr.. Tucker-The Old test provided fol
3 the Bunsen photometer and a round fame
/ burner. an Argand burner with-I thinh
! & xss-twelve holes. have been told
and II was told before this COMMITTEES
/ ten or twelve years ago. that that tes'
/ produced a Is candle power the new
/ test that IS employed now. with the fai
flame burner. pro0uces a ? candle power
/ and that there was the same gas. only
+ by a different test Is that a fact?
there that much difference between
round fame gas and A fat flame gas?
Mr. McIlhenny-We get all our testing
I laws from England. There was an act o.
Parliament creating a board Of gas ref
| erees for Great Britain. and they have
I gone into Il very scientifically Able meT
/ have been a. the head Of Il, and they
/ have gone into It. The first tests were
used by burners that We called -'Argand'
/ burners that is. a burner with a chimney
/ over Il, so that il would induce thC
I oxygen 20 come in contact, twenty-foui
I holes TO the burner. and that ran aionE
/ for years and years as test OF candle
power Then the law was not changed
I but the recommendation was made By
/ the referees that they be allowed 70 Us:
a fat fame. because they felt IL was
more exact test Of the gas, and there
/ was no aid to il, there was no chimney
over It TO induce more oxygen 10 come
/ in contact with il. and to-day al ovel
I the world. Germany and France. and al
i over the civilized world. the fat fame
7 Is used, and il Is considered A bettel
{ test than the Argand burner. and we ar,
l using IL here. OF course. because Il {,
/ used all over the world. We did no
/ adopt IL, other people adopted It. and ",
/ followed suit.
Mr.. TUcker-The point I wanted Z,
! bring out is this: Were We getting IN,
| same candle power prior 20 1895 with th'
/ old round fame test as We are gettin.
to-day?
Mr. McIlhenny-Precfseiy the same.
Mr.. TuckeT-There was a great deal O
/ complaint az that time about the csndl,
power Of the gas. remember member
OF the House OF Representatives caIn'
/ before this committee and testified tha
/ the gas was unsatisfactory. Now, thosl
/ complaints ars not nearly so numerous
/ The question is, Why is that7 Wert
you furnishing s larger amount Of Goa
/ gas than you are at this time?
I Mr.. McIlhenny-I win tell you. Mr.
/ Tucker. what happened here that mad,
( that great outcry about the quality o.
/ the gas Coal gas in It's manufacture
! produces, IN cold weather, a substane,
called naphthaline, which eecumulates Il
/ the pines It looks ike snow when vo1
( see IT, It is a white, crystallized sub
! stance. and Il is the richest part Of tn,
/ gas. 1t IS a rich hydrocsrbOn, and II
! cold weather. when the pipes come il
/ contact with the cold, It fills up tn,
pipes. One winter here think there wa:
/ hardly pipe in Washington that was no
