WILL EXHIBIT At PARIS
The Weather bureau to Send Ma
chinery to the Exhibition.
Professor Marvin Selected Today as
the Of.cinl Who In to Have Charge
Foreigners How the Service Is
Carried ON in the United states.

The Weather Bureau will send an ex-
hibit to the Paris Exposition. Prof. C. F.
Marvin, chief of the instrument division.
has been assigned by Chief Moore to at
tend to packing and shipping the exhibit
and to go with it to the exposition.
1t was not until within the past few
days that decision was reached to have
the Weather Bureau represented. The
space on the exposition grounds allotted
for the exhibit of the United States Gov
ernment is somewhat Limited and 1t was
feared the prognosticators would have to
remain at home. but Commissioner Cen
eral Peck was exceedingly anxious to
have the bureau represented, and he has
made arrangements for the erection Of a
building specially for the purpose.
Mr.. Peck recently declared that the
Weather Bureau should be represented at
the exposition il he himself had to pay
for the erection Of the building. As a re-
suit Of the uncertainty regarding the
building, the preparations for the exhibit
have rot progressed SO rapidly. but now
that the matter has been definitely decid-
ed, work toward packing and making the
necessary arrangements will be hurried.
The United States has the best
system Of weather representation Of any
country in the world. and there is no doubt
that the exhibit Of the bureau will eclipse
anything that other governments can offer.
Prof. Marvin has his plans as TO the nat
ure of the exhibit already defined. He
thinks that the value of the instruments to
be sent and the cost Of packing and exhib-
iting them will amount to about $4,000.
According to the pan already decided
upon, a thorough demonstration OF the sys-
tenn will be given. The Weather Bureau
building at the exposition will have among
other things a complete set of instruments,
such as are found at every weather station.
The workings OF the forecas;ing division
will be demonstrated, and to do this ficti-
tious reports will be made out from which
a prognostication will be made in the regu-
lar way. II has been decided to keep
American visitors at Paris informed as to
any unusual weather conditions which may
exist in this country during their absence
and to this end when conditions warrant 1t
one or two cablegrams will be sent from
headquarters here in Washington to the
station at the exposition.

of experience OF the employees of the instru-
ment division, which records the velocity

None Of the European governments has
anything like it. In order TO show a ma
chine which records rainfall artificial rain
will be produced. The thermograph which
registers the pressure of the atmosphere
will be shown. as well as all the instru-
ments in common use.
An apparatus employed at lake and coast
stations TO display storm signals will be
set up. as will collection of maps indicat-
ing special or peculiar climatic conditions
found in the United States large num-
ber of photographs will also be displayed.
The different types of kites used by the
bureau for scientific researches will be

air and the velocity OF the wind.
Prof. Marvin expects to be ready to
send portion of the exhibit in January
when the United States Steamship Prairie
Will sail on one of her trips to Paris. IN
less unforeseen circumstances arise the
exhibit will be ready at the opening of the
exposition. Three or four of the Weather
Bureau scientists will act as assistants 10
