OGDEN, Aug. 2S.-rhis morning
email party OF me- Lett Ogden over the
Southern Pacific for California alter
stay OF four weeks IN the vicinity Of
Ogden. Few people here X ow them
or know what they have been doing
the last month, rhey were, however,
distinguished men ia the!t Hoe
and their work during their
stay Will add much to scien-
tine data. The party consisted o.
Professors Msr6s. Wiag, and ao'kin
OF Leland Stanford univetsity, and
they nave besn at Ogden to maze
tests at the PJwot company's plant to
ASCERTAIN particularly the loss OF power
by friction OF the waters Of difierept

Therefore very valuable.
Tue OgdeD plant conslsts Of a long
pipe that carries water from the
bottom oil the dam that is to create the
great reservoir down TO the power
house whefe by use Of machines the
eLefpy OF the water Is transformed By
mGohInse Into electrical a energy.
The pipe which IL usually
eight miles long 10 constructed
o. wood bound with steel, nnu IL six
feet in diameter. Ii 10 laid as nearly Gs

The pipe makes curve after the

wheel that 10 placed just above IL. Tue
surface Of the wheel IL formed into
buckets somewhat li6e the o0gs on

to receive the GREATEST amount OF
energy from tho water as 1t apurls
from the six Dtzsles b,lOw. These
nczzles are rectangular holes about
three iqusIe inohes to each In the
curved steel pipe. Tho water PUSHES
from these and Its force against the
buckets drives tho wheel at tremsnd.

The work OF the California profes-
sors has been to determine the loss OF
power by friction when the water 10

tho pipe. There were two series OF
experiments, one on the wooden pipe
and the other on the iron PIPE, which

put In at different points and the
water turned on this relieved the pres
