"A fall of about thirty feet between
Lake Superior and Lake Huron ut Sault
Ste. Maria gives probably one of the
greatest water powers in the world. Itis
to be utilized on the Canadian side by
race and on the American side by
canal GOO feet wide, and giving 23G, 900
horse power.
it has been concluded that whatever
preservative is to be applied, the timber
for piles, subjected to the action of sea-
worm, should first be charred, so as to
kill any germs near the surface, open
the pores of the wood for the antiscptic
and destroy the nutritive matter upon
which the worms live. Scientific

AT a recent meeting of the Ioolog-
ical society, of London, Mr.. Boulenger
exhibited young specimens and eggs of
a South African siluroid fish (Galeich-

from the mouth of the male parent,
which carries in this extraordinary
manner the eggs laid by the female.
The treasury department estimates
that 500, 900, 900 pounds of sugar will be
produced in the United States this year
and that $40, 900, 600 will be required to
pay the bounty. Ninety-three per cent.
of the yield is from sugar cane, per
cent from the beet, about l. = per cent.
from the maple and the rest from
sorghum.
The watermelon business in south
western Georgia has been overdone, and
many growers will change their crops.
The man who bought the first carload
of melons in Fort Valley, the past season
paid $50 for them, and he thought he
was going to make small fortune on
the transaction. When the melons
were shipped the parties to whom they
were consigned surprised him by draw
ing on him for SIS. He was out just
that much on the speculation.
"A curious and interesting calcula-
tion has been made by Professor Rogers,
of Washington, D. c., on the dynamic
power of coal According to the pro-
fessor single pound of good steam
coal has within it dynamic power
equivalent to the work of one man foI
one day. Three tons of the same Goa
represent a mans labor for period Of
twenty years, and one square mile of {
seam of COAL having depth of foul
feet only, represent as much work az
1000, 900 men can perform in twenty
years.
The average weight of the brain o
man bears a definite relation to the
climate in which he lives, a heavier

The rapidity with which steel rail
have continued to replace those of iro
in the railways of this country is re
markable. In 1880 there were dow
1 33, $50 miles of steel rails, out of 115, GA
, miles of road reported upon, or 80. 1 pc
cent. In 1885 the steel rails had il
? creased to 5,724 miles, or 62.9 pc
t cent, and at the end of 1890 accordin
. to Poor's Manual the steel rail milag
t had reached 167,6 miles, or SO.4 pc
5 cent. of the whole milage reported, il

l increase seems to have averaged NOR
Y than 5 per cent each year, ana at tha
