The thistle at the antipodes seems to

feet, and this root, even when cut into
small pieces, retains vitality, each piece
producing new plant.

A mortar which it is claimed will stand
in all sorts of weather is made of one
bushel of unslacked lime and three bush

pouLd of alum mixed with one pint of
linseed oil. The alum will counterfeit the
action OF frost on the mortar.

According to Schubater, the majority
of plants produce larger and heavier
and this according to him, is due to the
long duration of tho days of summer, and
to the long exl osure to the sun. Beans
| carried from Chrls'isnia to Dronthein
have furnished in the latter locality seeds
that have gained sixty per cent. IN weight.
Thyme from Lyons, plants at Drontheir,
have gained stventy-ohe per cent. in
weight. Ou the contrary, the seeds of
northern plants, developed in more tenn
perate climates, lost insweight.
Electric heat indicators, consisting of
thermometers incased and protected by
| iron tubes, provided with piatiz um wires
and connected to a system of electric
bells and indicators on deck, are the
latest invention FOR preventing spontane-
Gus combustion among ship c4rgots.
Should any undue heat arise in any part
of the cargo, the mercury in the Their

the platinum wire, and give aa instan-

| exists.
Experimental firing with the new
British military riff at ranges beyond
| 1000 yards has given the following re
| suits: The targets were small field for
| titications ten yards long. The firing of
| yolleys by about thirty men, was almost
wholly from direction, sighting being
| impossible, owing to the hezy weather;
| yet at 1000 yards out of $40 shots there
were 159 hits; from 367 shots at 24OO
| yards there were So hits; ard from
269 shots at $50 yards there were 104 hits.
Penetration at the extreme ranges had
| been thought doubtful, but some bullets
at $500 yards struck an iron target and
were broken TO pieces.
As q possible theory of the origin of
the Mississippi, Messrs. Robert Bates and
John A. keyep suggest that its erosion
was accom- piished by means of a mighty
cataract which begins far down the river
near its original mouth, and by gradual
retrocession dug out the valley-like
gorge VIII CHI is SO marked q feature IN
the upper part of Its course, and left he
high bluff walls on either hand. This
view makes St. Anthony's Falls the ever
decrea ing and receding remnants of the
once most stupendOus cataract the world
ever, saw, having perpendicular de-
scent of perhaps 600 feet. The time re-
quired to cut the entire chanpel is placed
at 100000 years.
