yOH, De altogether manu- WIN az 4'elAN
rock.
Freeman division, No. 6, is about
twenty-one miles long, covering the
route from Red Rock summit TO the
Indian Wells siphon, and is aitogether
cut and cover work of easy character
Much Tunneling Done
Jawbone division, No. z, is 21.9 miles
long. Construction work was begun III
September, 1908. The work so far, ASIDE
from the preparatory work of ROAD
building, power line construction and
laying of pipe lines, has been mainly
confined to tunnels, of which there Is
an aggregate of 1850 feet in the dlylso
ion. At the present writing about S5OO
feet of tunneling has been completed,
and it is expected that all the tunnels
with the exception of Nos. 80, 80, 3D.
40, AZ and 40, will be completed in the
next fiscal year. Concreting will be
started as the driving of the shorter
tunnels is finished, and the progress
should be such as to accomplish the
completion of the lining, with the ex-
oeption Of the tunnels named, within
the year.
An electrical shovel is now on the
ground and will begin work by Janu-
airy 1 in section of the division, to
the cut and cover portion. There are
38 900 feet of this work, and a rate of
ably be expected. This would complete
about 10000 feet of this work by the
end Of the fiscal year.
Mojave division, No. 7, is % miles
long. Work has been begun at a
point where the aqueduct intersects
the Southern Pacific railway, about
four miles north of Mojave. About 1000
feet of conduit has been completed so
far, and the rate of progress should be
maintained at about 1000 feet a month
for each shovel.
Completion in Two Years
The Austin excavator is being erected
about ten miles south of this point,
which, it is expected, will be ready for
operation about December 10. This
will make three gangs at work on the
Mojave division, and will render posi-
BILE an aggregate of 5000 feet a month.
At this rate 1t will require only about
two years to complete the division, so
that it will not be necessary to increase
the force.
Antelope division No. extends from
the northern end of the Antelope val
ley Cottonwood siphon to the Fair
mont reservoir, a distance of 267 miles.
Work has already been begun on the
southerly end of this division, which
consists of eleven miles lying southerly
from the Antelope valley siphon.
Elizabeth division No. 10, of which
Elizabeth Lake tunnel is the most
prominent feature, is being driven with
undated vigor the progress at the
present time being at the rate of about
800 feet a month. 1t is expected, how
ever, that this will be somewhat in
creased by the additional two headings
reached by a shaft located 5000 feet
from the north portal. Fourteen hun
bred and forty-six feet of tunnel have
been driven from the north end. and
about '2900 feet from the south end.
The proposed Fairmont reservoir IS
| in this division. Work of stripping
for the dam is already begun, and the
building of the dam itself will be start
ed early in the year. provided a suf-
ficient amount of water for sluicing
operations can be accumulated.
Saugus division No. II is, topograph-
ically, very rough division, covering
a distance of 14.4 miles, from a point
| in the San Francisquito canyon to
the south portal of the Newhall tun-
mel. The working camps have been
established in this division, as well
as main headquarters at Saugus juno
ton on the Southern Pacific railroad.
1t is intended to prosecute work Wig
orously on this division during the COM
ing yeaA
There are thirty tunnels in the di-
vision, aggregating 7.64 miles, mostly
through a soft formation. All these
tunnels are comparatively short with
the exception of tunnel No. To-, which
! is 9100 feet long. The rate of progress
| should average at least six feet per
day at each heading, so that the short
tunnels will be ready for concreting
quite early in the year. Should funds
permit. work in this division could be
expedited so that all the tunnels but
No. 1O3 could be completed and lined
| in year and half.
The following is summary of the
work which, it is expected, will be
done during the coming fiscal year on
| the whole aqueduct, together with an
approximate estimate of its cost.
| The estimate of construction for the
fiscal year ending November 30, 1909,
gives So. 65S lineal feet of tunnel ex-
cavated and lined; S6140 lineal feet Of
| tunnel excavated, and 1882 feet or
conduit excavated and lined.
The estimate of money required for
such work is as follows:
