! and smaller animals have all been fol
lowed to their native heath and photo
graphed. The. eyes of the animals in
! his pictures often show the wild, star
tied look that comes to those who are
suddenly surprised.
Mrs. Gene Stratton-Porter is another
indefatigable worker with the camera
in the interest OF science. Her studies
of birds have made her famous, and
each picture has been secured at the
greatest personal inconvenience. When
she. goes TO photograph nest of eggs
or birds. she first gets acquainted with
the mother"bird, sometimes taking
weeks to do it, but finally holds the
little creature in her hand and handles
the eggs without fear of the family
! being broken up. To get a picture of
certain shy swamp bird, she drove n
! distance of fourteen miles every day
for week. wading through deep
marsh and carrying her heavy camera
obtained. She has secured excellent
pictures OF eagles and owls in their own
particular haunts, and spent many
weeks in neighborhood getting ac-
quainted with colony. of vultures.
The two greatest discoveries in this
art at the present day are color pho
| that the chemical action of colored light
has no power to produce hgments of
| the same color as the light itself, but
| the problem Of reproducing the colors
of objects was solved by the principles
of interference, discovery of New
tons that is exempli6ed in the colors
of soap bubbles and mother of pearl,
and which is an application of certain
theories In regard to different wave
lengths. The first pictures in this pro-
cess were brighter than the original OBJ
jects, but this is being corrected
through careful experiments. Prof.
Roentgen of Wurzburg gave to the
medical world that invaluable aid, the
X-ray machine. Since metal and bones
covers deformed joints, splintered
bones, bullets. or bits of shell. By its
means great suffering has been relieved.
The assertion that photography is a
means of life-saving seems queer, until
it is understood that by its use figures,
pictures and letters are now transferred
to watches and clocks, and the men who
once lost their eyesight, and often their
entire health, at the work are now
emancipated from it. Astronomy owes
great debt to this art, At various
places throughout the world there are
observatorics erected by governments Of
colleges where pictures of the heavens
are made each night, to be carefully
developed and forwarded TO headquar-
ters. There they are labeled and put
away with the care and precision of a
newspaper file When the next consign~
ment of plates comes in, these are taken
out, and comparison made to show
any change in the geography of the
heavens. Very often important discov
cries have been made by this means.
The first work was crude. The al
out that a solution could be made OF
silver in muriatlc acid, that it made a
white salt called chloride of silver,
Daguerre saw that if sheet of paper
be covered with this and exposed to
the sun, whatever reflection it had
caught would be fixed there, the darker
shadows showing light and the lighter
ones dark; Many other people seem
TO have thought of this. but none of
them were successful with the work.
AS early as 1894 factory was started
in Soho, London, for the purpose of
making pictures by the help of the
sun, but wise artist named Beechey
was instrumental in having it closed,
seeing that it meant death to the por-
trait painters, trade, and the world has
learned nothing of the methods that
were then used.
In a measure all the scientific world
has made some contribution to the per
fection OF the art of photography, The
discovery of iodine in 1872, OF hypo-
sulphate of soda in 1919, and the use
Of collodion In 1850 all made the art
of today possibility, So did the work
the middle eighteenth century, who first
constructed the double achromatic com
bination of lenses. Daguerre made his
pictures on copper. In 1889 Fox Talbot
of England found that he could print
the likeness on paper, and he patented
the process. In 1850 Scott Archer of
England found that by using film of
collodion the shapes could be fixed on
glass and pictures on paper printed
from this, thus the negative came into
use.
The man who came TO us long ago,
and with his big magic lantern showed
pictures of yellowstone park k, the Yo-
semitic valley, or illustrated Ten
has passed far inland to the remotest
log schoolhouses. The stereopticon man
whose lectures would otherwise lack
many listeners, will soon follow him, for
close on their heels come the moving
pictures. the most wonderful accom-
plishment OF modern photography.
Many attempts were made before this
invention was completed. Muybridge
used up half million plates at the
Sacramento race-track in 1879, getting
his famous series of horses III different
poses The author s edition of the work
he produced after this is valued at
$4,000. The biograph was patented in
America i'll 1895.
The making of moving pictures for
use in vaudeville performances affords
a livelihood for large number of peo-
pie. Most Of tho American made films
are acted in New York, When a film
1000 feet long is to be made no small
amount of ingenuity is required. To
secure the effect of smoke from a dis
charged pistol n handful of tslcum pow
der ie thrown. The interior Of a big
hall or theater with stage paraphernalia,
or the roof of sky scraper furnish
much of the scene, although the hills
