Two improvements in the mechan-
ism of musical instruments are reported.
The first of these, an invention of Herr
Emil Olbricht, pianist, of Berlin, is q
scheme for raising the white keys of .
piano to the level of the black, or, ii
necessary, a little above them. The
other novelty is the Encouragement of
the holes of the bassoon, which is said
to make playing the instrument easier

Experiments to prove the virtues of
salt In keeping farm crops in healthy
and vigorous condition have been car
ried on extensively in some parts of
England, and the results lead to the
following conclusions: That dressing
Of 1,50o to 1900 pounds of salt per acre
will check the rust in cereals, the finger
and-toe in turnips, largely protect oats
against the grub and wire-worm;, check
the virulence Of potato disease. and
dissipate fungoid growths in pastures.
1t is also preventive against moss,
makes rough grass more palatable, and
sweetens the heritage generally.
"A paper goods manufacturer in
Dresden. Saxony, is sending to the
trade in this country sample tool
handles made Of paper. They are light,
and apparently strong and durable.
They closely resemble the ordinary
wooden handles, but are said to be more
durable than the latter, and have the
added advantage of never splitting
when driven into sockets, as the paper
will yield more than is possible with
wooden handles. The bore of one-six-
teenth inch may be Increased to three
fourths inch without injury to the
handle,
