"A much oughtdesideratum namely,
a really practicabl method of water
proofng leather and raw hides, is
claimed to have been praeticed by an
| Austro- Hungarian chemist, with much
success, his method being to impreg-
nate the material with a gelatine solu-
ton. combined with some mineral salt
to coagulate the gelatine in the pores,
ALI sounds, whether high or low,
loud or soft travel at precisely the same
rate, l. e., about LOO feet second.
Were this not so the different notes OF
music would reach the ear at different
times. and the result would be confu-
sion instead of melody. If the sun
gave forth sounds loud enough to reach
the earth, such sounds, instead of reach
| ing us in the space of about eight min
utes as light does, would only arrive
after a period of nearly fourteen years
An interesting incident showing at
how great distance conversation
can be carried on is related by Llent.
Foster, of the third Parry Arctic expedl'
ton, in which he says that he conversed
with man across the harbor OF Port
Bowers, a mile and quarter away,
and it has also been distinctly asserted
on rood authority that at Gibralter the
human voice has been distinctly heard
at distance of ten miles.

pork product, including pork, bacon,
hams and lard, from the United States
for the wear 1890 were 1,221, 900 pounds.
The total consumption of pork product,
exclusive of lard, in the United States
during 1890 is estimated at 1858, 0OO, oOC
pounds. which would make an annual
consumption per capita of over fifty
eight pounds. The domestic co4sump
ton of lard is about $40, 900, 900 pounds
or about S & per capita ia ='
