"A fisherman of Tn on Springs, Ala.
has invented an attachment to tishins
hooks which is quite an improvemc +
About midway Of the staff of the hook
he has placed a straight projection,
which serves three purpos es-viz: First
it prevents q fish from swallowing the
hook; second. when a fish bites al the
hook if his mouth strikes the projection
he involuntary closes it and is thus
caught; third, it prevents bait from slim.
ping up the hook. The hook has been
tested by several expert local fishermen.
and all pronounce it a decided success.

A Maryland journal seasonablv re.
marks that the idea Of planting edible
nut-bearing trees where shade is DIES red.
instead OF those which are solely ora.
mental, is not new, but the suggestion
is one that will bear thinking about by
those who contemplate planting shade
or ornamental trees. Chestnut, walnut
hickorynut and butternut trees are ali
nearly as fine in appearance as horse
chestnut and maple, and, aside from
the u of revenue which will in time
accrue to their owners from the fruit
the timber OF such trees is always in de-
mand, and the tree itself may become
profitable sho I'D it become desirable all
any time to rcmove it.
"A genius of Sing Sing, N. Y, has
invented a dry battery which he expects
will revolutionize the working OF tho
telephone. 1t is a little oblons box.
four and q half inches by one and ~
half, and t%hrce-quarters of an inch deep.
and is attached to the instrument instead
OF the ordinary battery. BY its use it isl
possible to carry on a conversation with
a person thirty or forty miles away, and|
to hear and be heard distinctly. Ihe|
inventor claims that his dry isattery will
last as long as the instrument without
losing it's power. He has had one in
constant use for three weeks, doing
work that would have used up the or.
binary battery in ten minutes.-M vi
