SCIENCE.

Prof II, W, Parker, of Iowa College,
has discovered some fifty animal foot
prints in the yincinity of Denver.
\ new mineral named "rechellite. ."
10y G. Cisere and G.. Despret has been
obtained from Richellc near Wise, Bel
gium. II occurs in large masses, cream
yellow in color at first, but aiterward
changes to an ochre yellow.
Herr Krupp, of Essen, has taken ont a
patent for flat-headed artillery projoc-
tile. II tapers slightly at the butt, and
not only pieIees the plates more easily
than the pointed kind. which are apt TO
defect when striking ir,n at certain
angles, but it is calculated TO hit the iron
clads below the water line.
An in,ombustible paper has been
made by Mr. G. Meyer The basis ofthe
paper is amCanthus. An indellible and
incOmbustlble ink is used with this
paper. 4 Telegraph made with this paper
and ink, when placed between two lay
ers of melted glass resisted the action of
the heat perfectly.
The rise and fall of the old lakes is
pulling the old settlers. At Grand Ira
verse Bay the water slowly risis for
seven years, and then reccdes for the
same length Of time. The Saul Ste. Ma
ric Democrat says that the water in the
800" is lowering every day. At Ira
verse City the water is encroaching on
the west side Of the bay.
4 breeder of canary birds, short
time since, conceived the idea Of feeding
a yound bird with mixture of stepped
bread and finely pulverized cayenne
pepper, with the view of changing the
color of its plumage. 1t is asserted upon
good authority that, without injuring
the bird, the pigment Of the spice passed
into the blood and dyed its plumage a
very deep red.-Trov Times.
In paper read before the London
Society of Arts some interesting particu-
lars are given as to the savings affected
by science in various industries. Among
others, it is related that, whereas the in
side and outside-husks Of silk cocoons
used to be considered useless and thrown
away, they are now considered of great
value, and in the United States alone,
from 2000 TO 5000 bales Of waste silk"
are used up annually at value Of over
81 .0OO0OO
The scientific American mentions the
decline in the price of COPPER as likely
to lead to an increased demand for that
material in building. At p. esent the
material for copper roof costs only
about half as much more as tin, and as
the latter must be replaced and repaint-
ed about once in three years, and in fif-
teen or twenty years needs replacing al
together. the copper, which never needs
painting, and which is practically indie
structible, is much the cheaper material
in the end
Useful applications of electricity con-
tinue to multiply One Of the latest is
to use it for running a pump for raising
water. A machine invented in Vermont
has been tested at Middlebury during
the past Summer, with very satisfactory
results. 1t forced water from creek
through 700 feet of pipe up an elevation
ofeighty feet, delivering sixty gallons
per hour. The comparative cost of this
power over the Windmill has not been
determined, we believe, but il has the
advantage of being constant, and doubt
less will become, if 1t is now, cheap as
well as an effective source uf power
