1t has been calculated by Prof.
Rogers. OF Washington, that the dynam-
ic power Of a single pound Of good
steam coal is equivalent to mans
work for one day; three ton, for twenty
years, and one square mile of a seam OF
coal only four feet thick will represent
the labor of a million men for twenty
years.
"A now candle has been brought out
which extinguishes itself in an hour.
This 1t does by means of q tiny ex NJ

The scientific authorities in Europe
seem to have decided that horse-aesh

"A plan has been contrived for gen.
Grating steam for motive power at the
smelters, through the use of Stag, the
latter being dumped into large, shallow
vessels, which are afterward run under
boilers. and the heat used in general
ing steam. In some experimental tests
of this new method it was found
capable of maintaining as much as
seventy-five pounds pressure on
vertical boiler for seven days, thus in
suring great economy.
In lecture on Foods" recently

with thos. furnished by milk, namely,
86 per cent. water, 8 per cent. fuel
per cent. flesh. formers, and or per
cent. mineral, we might almost look
upon the banana as condensed milk.
According to Professor Sergeant,
the strongest wood in the United States

Arkansas region, and the weakest the
