Cure0neP Patient
Of A Fever

- AKING the temperature of the biggest man-made
thing earth and reducing fever in the steel
and concrete monsters the hardest job Of it's kind
ever undertaken by engineers. The patient is the
Grand Couce dam on the Columbia river in the state of
Washington.
While unaided by the patients usual protrding tongue
and grooming Ah-h" the Bureau OF Reclamation United
states Department Of the Interior has Just announced
temperature readings reports that fever
has abated sufficiently TO allow the uRmagiRaby power
fIl patient to go to work.
Described by the Eighth Wonder Of the
World" this mighty contains enough cemcnN TO
I'm train 900 miles long and enough sand and gravelNo
load freight train extending from coast to coasrains
with the caboose thousand miles into either ocean The
base 40 acres dwarfng such ambitious
dertakings Is Shasta and Boulder
Temperature in concrete result from the expansion
during the hardening process and from
traction the concrete cools The cooling of mass of
huge Grand Coulee would take ordinarily
a hundred years During the cooling period, the dam
would continue to contract and crack
Temperatures high as 1872 degrees Fahrenheit were
recorded Coulees early life. The engineering
the opinion that their gigantic patient
must ultimately have its temperature lowered TO the mean
annual temperature TO which it was exposed
IN order to eliminate its, and their headaches
Cracks in a structure like Grand Coulee make proper
distribution impossible and water leakage pre-
SCENTS annoying and costly maintenance problem Be
sides hundred years long time TO wait in go-gettng
America determined that by laving the giants
brow and cooling lis nsdes the temperature could be
brought normal eliminating at least % years of
harmful # not dangerous, contraction
Cooling operations and the taking OF temperatures were
December 1886 and continued up 10 early last
wear Two types resistance thermometers used
thousand hundred and seventy-three of one
kind were inserted tho big fellow locations which
would give representative temperatures and the second
type placed IN the ends Of cooling coils in shafts
These thermometers hooked UP with big terminal
board doctors the job day and night could
read the temperatures parts the patients towering
and sprawIrg body terms of degrees Fahrenheit
II wasn't enough just have the patients temperature
Means of reducing the fcycrsh condition must be devised
While doctors sweat baths and q"nnc To bring
down temperatures the engineering WtHcos kne" the
peculiar autipathy of their patient such measures So
they worked iron, the inside out mstr" OF from the
outside
Tn, water in Grand CouIcc Reservoir has a mean
annual temperature Of 40 degrees Fahrenheit but the
temperature the water flowing into the reservoir varied
during year from 30 to 60 degrees with lowest cmpcra-
