! serVatorv, the Lowell observatory
Indiana university and an indie
pendent British observer are at En-
/ senada, Lower California, for thu
total eclipse of the sun next Mon
dav. Several thousand dollars
worth of material has been taker
, by boat and by the coast road from
/ the border, and the most of this
has been placed in position.
The Indiana university party, il
chargo of Prof. w. A. Cogshall
head of the astronomy department
there, has constructed 55-foo
pine tower in grove a mile south
west of Ensenada, where they have
mounted 63-foot camera with
nine-inch lens. Prof. Cogshel i
planning to utilize this instrument
to obtain seven photographs of the
corona of the sun during the periot
of totality.
He also has mounted a large re
flector. with which the image OF
the sun is photographed by the use
of a mirror.
Mucn Equipment ldkeN
The Lowell observatory party
headed by r. G. Slipher of Flag
staff. Ariz., will devote its atten
ton to a spectroscopic study of the
sun s corona. The Lick observa
tory has taken in several tons ot
equipment to make general obser
vations. Their headquarters are
nearly 10 miles south of Ensenada
Humphrey Hargraves, a British
astronomer, has placed instrument:
near the Lowell and Indian par
ties. He is using equipment whicl
he used recently in Australia dur
ing 81 total eclipse there, where at
tempts were made to prove or dis
prove the Einstein theory. Mr.. Har
grave is working independently.
Ensenada citizens are preparing
for great numbers of visitors wher
the eclipse will be an added attrac
ton to the picturesque Mexican
town. Gov. Lugo of the northern
district of Baja California will ar
rive at Ensenada Thursday, accord
ing to word received yesterday anC
will stay until after the eclipse. HI
will be accompanied by staff o.
officials and the 4U-piece stat
band. Through United States Con
sui Hope at Ensenada the astrono
mers have made application to th'
navy department to send an Ameri
can destroyer there to carry th'
Photographic plates exposed during
the eclipse to San Diego on Mon
day night. In this way they hops
to avoid the rough road to tn
border.
New Station Established
A new eclipse, station has beel
established at Point Iona. J. T
Oult and II. F. Johnston of tn
Carnegie institute of Washington
are setting up the. instruments witt
which they will study the effect o
! the eclipse on the earth s magnet
field. Their station is on Poin
Iona just beyond the old Span
ish light. It is much easier to visi
than the Mount Wilson station a
the extreme end of the point. an
| those not INCLINED to travel tn
steep and rough road TO the end o
the point are satisfied with tn
less imposing installation.
The Carnegie observation static
will be in operation by Thursda
for the data sought by Ault an
Johnston is comparative and dc
mands a series of observations be
fore and after the eclinse to CON
mare with the data collected dun
ing totality. In addition to ot
serving the effect of the eclipse o
the earth S magnetic field, the Ca
negie expedition also will measur
the changes in the electrica
charges on the earth s surface. Tw
potential gradients are being il
stalled for this purpose, one PEI
fected to record its results phot'
graphically. These instruments wi
be handled by Mr.. Johnston.
The Carnegie expedition include
only Ault and Johnston, but b(
cause they need the assistance of
number of trained scientists I
make the proper visual readings G
their instruments, five members q
the faculty of the State college her
will help them.
In Final Stages
Work on the Mount Wilson Q,
petition 3 instruments is now j
its final stages, according to +. {
Pease, designer and constructor {
the instruments. A great canvc
screen is to be erected at the yves
side of the temporary observator
to protect the instruments from I'll
wind. The two Einstein Gamers
must still be covered to make thel
light tight. Platforms are to /
built for the scientists who are {
operate the instruments; and theI
are to be many drills. Every ev
ming those of the expedition WI
are already on the ground are NAL
ing tests with the stars and al
correcting any little discrepanciC
they discover.
