story office bldg and an office for
Govt Inspectors. Work on gravel
trestle is nearing completion. On
Splllway channel floor near end
OF gravel trestle, concrete footines
are placed for concrete mixers. A
belt conveyor will carry AGGREGATES
from the base of stock piles to bins
over the mixers. Heavy, wood
frame cemeut storage bins are
being built on same level BERN on
which aggregate piles are located.
Cement will be pumped from bins
to mixers. Laying and ballastine
of tracKage for construction purpos-
IS is being performed rapidly. A
switching locomotive is on hand.
from the new transformer bank
near job office several electric DOW
er lines are being erected to serve
plant and lightning needs.
Govt dredges during 1st half of
June put over 100000 Gu. yds of
I'LL in dam, which exceeds amount
placed in last half of May. A to-
tai of 7,775,000 GU. yds. have been
pumped into dam to date. Dredee

Madison has finished her booster
slip 4 is now digging in river chan
mel. Dredges Jefferson & Missouri
nave been pumping thru extreme
ly long pipelines. While lengths
OF lines vary from day to day due
to discharge points selected on fill.
both dredges have had 10000 feet
lines.
The 80O-foot channel thru dam
is now fairly well defined. To pro-
tect channel slopes, blanket lay
ers of gravel are being placed. Sand
bags are used q sides of wooden
spin Us.
AT upstream portals of tunnels
Mason & Walsh are building an
other concrete mixing plant. Also
a bulk cement silo. Bulkheads
are built under r. r. trestIe to d.
vide piles of aggregate. Inside the
pilot tunnels IS. 900 lbs of struc-
tural steel beams were placed in
Nos. |, 2, & 3 in connection with
the shaft foundations. Excavation
continued in No. 4 tunnel epa
atory to placing of steel.
AT control shafts, the enlarge
nent Of No. | main shaft is down
LOO feet; No. 3 is down 1903 feet.
Nos. 2 & 4 emergency shafts are
Down IS and 122 feet respectively.

# cement grout is pumped between
he steel liner sheets & the rough
hale excavation. The mix used
or this grout is about 1 part sand
o ~ parts cement.
AT the lower portals, excavation
ontinued for the south retaining
all. Five base sections, 4 mid
ectionS & | top section of retain
lg wall requiring 200 Gu. yds. of
oncrete were poured during the
eek. Excavation in open-cut
ortlon of Tunnels has been COM
a total of $4,000 Gu. yards
ave been removed. Likewise, to
:ructural steel bracing has all
cen placed in these 4 cuts. Steel
cams whose weight totaIed
$4,000 lbs. we're used for this
In connection with this
me work, 6 inyert blocks and 9
CHI monoliths were poured requir-
6 5000 Gu. yds.of concrete.
Material delivered by the Govern
cut to the Mason & Walsh Co.
lring the week were as follows:
100 tons sand; 1900 Gu. yds. fine
avei; 5000 Gu. yds. coarse gravel;
100 bblS. bulk cement: 1000 bags
cement and $4,000 gal. of blum
Gus sealing solution.
A system of narrow-gauge
ackS is being installed on the con-
etc floor channel at the lower
rtalS. These tracks will be used
haul muck resulting from the
of the pilot tunnels.
