the work that had been accomplished
In the six months of labor. To be sure
the delay in the completion of the
spillway disQuieted him little.
The dam had reached the spillway
level a fortnight before, and had now
passed it. Indeed, on the fifth of Jan
uary the dam builders were within
five feet of the top; that is, the crest
of the dam was 100 feet above the
level of the valley. They had planned
to run the spillway around the east
ern end of the dam. The rock drills
and dynamite which had been ordered
by putting as many as possible to
work on the spillway Vandeventer had
succeeded in opening it for it's entire
width to an average depth of about
seven feet below the intended top of
the dam; that is, it was now about
two feet deeper than the actual crest
of the dam, but it still lacked five feet
of its designed depth.
The rainy season, an inspection of
the records had Rnown, was not due
for month ana a half yet. That
would give him ample time to COM
plete the dam and the Spillway. This
year, however, there had been some
very unusual rains during the fall and
the water back of the dam was now 9S
feet deep, which made it % feet below
the level to which the dam had risen
and 20 feet below the spillway. This
was much more water than anyone
had dreamed would be in the reser-
Voir ut that time, and was perhaps
more than should have been allowed.
Still there was safety margin of
% feet, which Vandevepter was sure
would be ample. The financial promo
ters of the project were very anxious
to have the reservoir full when the
irrigating season opened, and the en-
gineer's judgment had been influenced
by their eagerness to get it working

into the valley for many miles. In
fact, the dam had transformed the
country into beautiful lake. Some
times it rained in the mountains when

and there was a constant, if very
small, rise in the level. Vandeventer
personally carefully gauged the water
every day. Naturally he had noted
that it rose gradually, but as the dam
rose prOpOrtionately more rapidly, he
was not uneasy. Yet, as q good en-
gineer, he was watchful aid largely
because of the unfinished spillway he
urged the men to the very Limit.
The weatherwise from the town
who sometimes rode up to inspect the
work, assured Vandeventer that it
could not possibly rain before March,
and the mere fact that so much water
had fallen rendered it more imprOb-
able that any more would come down.
But at three on the afternoon of Jan
uary sixth it suddenly began to rain
hard without warning and with no
premonition on the part of anybody.
1t was not one of those terrible down
pours known as clOudbursts- but it
was an excessively hard, steady rain.
The heavens over the range were
black with clouds and so far IS any,
one at the dam could see, it was rain
ing from the crest of the mountains
down. There were some anxious dis
cussiOns in the dining room of the res
ident engineer and his American as
SiStantS.

open the undersluice gate about half

close the sluice once more.
