1.-THE foregoing estimate of probable l
| cost is made according to our best judg- q
ment, using the results of our personal t
experience and all the data we have f
been able to collect of the cost of large e
works of similar character, but 1t should d
be clearly understood that the modif- L
cations of the line and grade of the 7
aqueduct proposed by the board have i
in some cases carried the new locations +
beyond the limits of the definitely
mapped topography on either side of
the located line.
"In the most difficult sections, how t
ever, our revised location has been in il
strumentally re-eXamined in detail and
checked. a
"In less important places where 1t e
was manifest that there was no mate S
rial changes of material within short h
distance of the original location, the es- "
| Inmates have been made on the original o
| lines, generally parallel with and not fl
far distant from the new line. a
I'm forming our judgment of the cost a
| of excavation. we have been guided in n
part by our own observations and in o
part by the notes of the classification
of materials made on the ground by the "
| field engineers. f
I'VE have assumed that the cement h
will be manufactured at a cement mill, o
to be erected by the city on property 81
already acquired, and that the cost of Il
the cement at the mill will be 81 per q
barrel, which is substantially the cost a
as determined by Edward Durkee, the s
cement expert in the employ of the o
city. s.
"The figures are based upon the as d
sumption that the work will be done b
on business basis, unaffected by poll f
tics, and with able and honest men in O
charge of all departments of the work. II
They are intended to include all money a
already expended, to safely cover the
contingencies and delays ordinarily met p
with in this class of work, and include II
an allowance for the extra cost OF the S
work on the eight-hour basis as com Il
pared with the ten-hour basis, on which Il
most of the large engineering works II
have been constructed, whose cost data h
are available. is
Time Required to Complete Project q

"In our opinion Ave years is the min n

can be completed so that water from p
the owens river can be delivered into p
the San Fernando valley.
"The controlling feature in determin- Il
ing the time is the long tunnel, the t
