for a month and q 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 98
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 at that time, and was perhaps
more than should have been allowed.
Still there was a safety margin Of
% feet, which Vandeventer 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.
The broad sheet of water ran back
into the valley for many miles. In
fact, the dam had transformed the
country into a beautiful lake. Some
times it rained in the mountains when
it did not rain down in the valley
and there was a constant, if very
small, rise in the level. Vandeventer
personally carefully gagged 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 good en-.

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 il
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.

hard without warning and with nc
premonition on the part of anybody.

with their days work the little group
soon broke up and each man went to
his quarters.
Vandeventer, however, could DOT
sleep. The rain kept up steadily all
night. The resident engineer finally
got up and dressed himself, and pre-

his quarters and went out to inspect
the dam. He carried a lantern. Of
course, for it was pitch dark AMI, II

He was surprised when he got to the
dam to see on the other side another
lantern. Closing the slide Of his OWE
lantern to prevent observation, and be.
ing on familiar ground, he went
straight toward the other side. The
noise Of the rain subdued any soune
that he made, and he was able to come
quite close to the other light without
being noticed.
