New Applications Of Moving Pictures"
10 the title Of an article in the June num-
Der OF the Spanish edition Of the Bulle-
tin Of the Pan-American Union. Of which
the following is the English version:
The value Of the moving picture in
science and education has been recog-
nized for several years. but not until last
year did the United States Government
begin to use It extensively in connec-
work Since then. however. the bureaus
of several Of the executive departments
have had their operators at work. with
ehe result that many thousands Of feet
Of dlm have been exposed and a COM
psebsusive exhibit of governmental ac-
tt~1ties shown in motion pictures is now
available. In the April number Of Amer-
oan Forestry published In WASHINGTON.
D. c. an interesting article by J. C..
Blanchard. statstician OF the United
States Reclamation Service, describes an
extensive tour Of some of the Western
States, undertaken last summer for the
purpose Of collecting photographs and
moving pictures Of the various enterprises
IN which the Government Is engaged In
that section.
Tho trip covered about 1900 miles Of
reclamation territory and included sub

About 10000 feet Of hlm were exposed
and 800 negatives Of still pictures were
taken. Among the subjects photographed

the Rio Grande Canyon. near the Tex
as-New Mexico boundary; an ostrich
farm. where 1000 full-grown birds were
driven directly toward the motion-pic- |

activities are shown by the films made
under the direction of the Bureau of
Mines. the Geological Survey, the Life
Saving Service. and other bureaus of
the Department of the Interior. All of
these moving pictures and photographs
are to be shown at the Panama-Pacific
Exposition. and later before popular au-
licences throughout the country.
In science one of the most recent uses
to which the motion picture has been
put. according to an article in the Sci
entific American (New York;. is in pho
tographing by means Of the Roentgen, or
H-ray. the motion of various organs of
the human body. The older form of ap-
paratus for making X-ray photographs
made use Of a continuous discharge
vacuum tube, and a more or less pro-
onged exposure of the PHOTOGRAPHIC
plate. This method sufficed for diagnos-
ng fractures Of bones, or for revealing
he presence of foreign substances. etc,
