found to have a greater circumference
and to be capable of lifting a greater
weight than the right, while the left
hand pressure, as tested by the dyna-
mometer, was also greater than that
of the right; this superiority of the
left upper limb of the stoker is attrib-
uted to the effects of shovel stocking,
the left hand and arm being called on
for greater effort than the right.
Scientists in America, according to
Harper's Weekly, are turning their at
tention toward the practical possibil-
ties of phosphOrescence. The researches
of Prof McKissick, of the Auburn
(Ala) Polytechnic Institute; Prof. Hal
lock, of Columbia, and others, prove
that darkness is, after all, only a rela-
tive term; that most, if not all. common
substances store up sunlight during the
day and emit ii in the form of more or
less powerful rays during the night
Prof. McKissick has been able to dis
Germ the emission of rays from over
dozen Well-known chemicals which had
previously been exposed to sunlight
and from such common substances as
chalk, glucose and sugar; sugar of the
common brown variety was found to
yield the most light. Not only was
Prof. McKissick able to take photo
graphs by means of this light, but it's
quality was so similar to that of the
A-ray that it affected a sensitive plate
through an intervening thickness Of
two and a half inches of wood. Prof.
Hallock is of the opinion that some
practical use might be made of the
properties of phosphorescence, and
points to the way in which nature
lights the ocean depths, and to the
light Of the FREELY, as examples of
what can be done. He thinks that
much practical utility might be gained
from the universal use of luminous
paints which could be spread in dark
railways and on the walls and ceilings
of office buildings to help out the twi-
light In fact, it would seem that we
are near to the secret of phosphores-
cence. When such common substan-
ces as sugar, glucose and chalk are
found to absorb sunlight all day to
give it off in rays during the night, the
discovery OF some means for rendering
those rays visible does not seem like a
very far cry into the future.
For the St.Louis Fair the exhibit of
the Department of Biology will be pre-
pared under the direction of DR.. F. W.
True. Probably the most striking OBJ
ject will be a model of a whale. eighty
or ninety feet long, showing the APP
pearance of the greatest of all living
creatures. Large game from all parts
of the world will be shown, including
such animals as the rhinoceros, lion,
giraffe, Gland and various other ante
lopes; the moose, caribou, red deer,
samibur, and other large deer; together
with various small species, such as
wild sheep, goats, etc. 1t is expected
that these will be perfect examples of
their kind prepared in the best style
of modern taXiderny. An attractive
collection OF a thousand or more live
birds will be exhibited in a mammoth
bird cage" to be erected near the
government building This original
and pleasing plan inaugurated by DR.
True, cannot fail to delight the visit
ors to the fair. The cage is now be-
ing designed by the supervising archi-
tect of the Capitol. The birds will be
collected and furnished by DR.. Frank
Baker of the National Geological
Park and the exhibit will be under his
immediate auspices. The cage will be
nearly 200 feet long by 100 feet wide.
so that the birds can fly about at will.
1t will contain the most characteristic
birds of North America and the trop-
les, notable for their brilliant colors,
sweet songs or peculiar forms. Moth
ing similar to this on a large scale
has been attempted at any previous
exposition and it is expected that II
will prove a most popular feature, as
well as give an opportunity for ac-
quaintance with our most noteworthy
birds. The cage will be fitted with
trees and shrubs, pools and running
streams, where the perching birds can
find shelter and the aquatic bros
proper exercise.
