Tombstone epitaph., 1917-07-15

earth dam may seem a temporary ex-
pedient, although most Of the great ir-
rigation dams Of the world are Of that
character; and everybody knows that
If the water should rise high enough to
overflow an earth dam II would not last
longer than 1t takes to describe its
utter giving way. A food would sweep
II out Of the way at once.
The device whereby possible foods
are controlled and such dangers avert
ed. consists of broad channel at one
side OF the dam, and at such a dis
lance below its crest that II, through

the height of the water is increased
until 1t promises to overflow the dam,
this opening will carry of the surplus
harmlessly. An earth dam without a
spillway would presage almost certain
destruction to all who lived in the val
ley below it.
In the case Of the Picket Wire dam.
the spillway had to be cut and. in part,
blasted out Of the mountain side-that
is, through the spur of the mesa. which
reached down from its high wall
towards the narrows. There had been
a series Of blunders and mishaps,
which included the explosion Of q ship.
ment Of dynamite on the railroad. with
very disastrous consequences to accom-
panying rock crushers and mixers, and
other machinery. The spillway had not
been completed. Its opening should
have been about twelve feet below the
level Of the dam. Vandeventer was not
responsible. of course. The chief engi-
neer had fumed and protested. but had
been directed by headquarters to 60
ahead with the other work and tackle
the spillway later. There was, indeed
little reason to hold up the building OF
that particular dam because of the
noncompletion Of the spillway.
That was a country, so the most de
voted inhabitants freely admitted, in
which it was always safe to bet that
II would not rain, no matter how
threatening might be the appearance
Of the sky; for in ninety-nine times out
of hundred the negative would win
the bet. Said inhabitants did not say
the hundredth time might compensate
for all the other failures. The weather
was like the little girl with the pro.

was no doubt in anybody's mind as to
the fact. Sometimes the fountains OF
the great deep, which, in Holy Scrip.
ture at least, extended overhead, would

Outside the rainy season cloudbursts

beneath carefully tabulated reports OF

Sen the right season for the building
of the dam, but when its crest began
to rise above the designed level Of the
spillway the delay in opening the chan
mel gave cause for some alarm. 1t is
not the probable or certain that Is
feared. An old version that, Of "omne
ignotum pro magnificent Is only the
unknown of which men are afraid, OF
only the unknown to be feared! Still
there was nothing Vandeventer could
do but obey orders and go ahead. The
danger, after all, was trifling. Another
consequence Of the waiting was that
in his inability to work on the spill
way, he had more hands TO devote &c
the dam and 1t rose the quicker.
The shape Of the country behind II
was such that when the Picket Wire
flowed with sufficient volume to fill it
a long lake going back through the val

hills for some miles would result. Ir
