time so remote as to have been for

The discovery was early made that

when wood pipe has failed, It has
most often been due to imperfect wa

have given trouble or failed to prove
durable, but on the other hand. no
pipe OF any design or material has
invariably proved satisfactory with
h result that engineers have been
constantly searching for some water
conduit more satisfactory thar any
material heretofore on the market.
Improved Processes
Impelled by this demand for I'm
proved materials and construction
for water pipe, has come an evolu-
Mon in the manufacture OF the mod
sfn wood pipe. which fs now bring
ing It more prominently to the At
tention OF communities interested In
water works construction than ever
before. Through a study Of the i'm
PROJECTIONS and defects OF wood pipe
construction in years gone by. I'm
provements dn the industry have been
effected BY engineers and wood pipe
manufacturers until the wood pipe OF
today is as far advanced as a water
carrier over the wood pipe OF q de-
cade ago as is the 1929 automobile
as a passenger carrier an improve
ment over its prototype OF the
nineties.
One Of these outstanding improve
ments and one which IL itself has
caused wood pipe to take a place IN
the class Of permanent construction
10 the use of wood preservative In
treating the slaves. As above stated.
wood saturated with water will not
decay, but It has been found that in
actual practice conditions seldom
produce constant and complete satur-
alton Of the wood. How has this
drawback been overcome!
Creosote Adopted
The manufacturers have taken note
Of the results obtained in Europe and
this country In preserving wood
throueh the impregnation of creosote
oil. They have learned that in Eng
