Prof Sartori, Of Treyiso, }. claims to
have discovered a process by which TIA
ly,will save S100, 900, 600 year in the
matter; of silk-worms. II, Thesiking or
defed at his own expense a movable
house for Reproducing the worms on
this process It--is-.yery xdifficult to

ID .--Complaintssi are made all over the
West that wire fences attract lightning,
which often results in the killing Of
stock. The stock. imagine. that the fence
afferds protection from the storm and
accordingly huddle: close tlpatoait. One
instance is given where siXtE-fye head
of sheep were killed IN. Nebraska at a
single stroke, sand another where ten

Since the introduction OF dynamo
electric machines good many valuable
watches have been almost completely
ruined iby having theirworks magnet
lied. Mr.. Maxim, the electrician, has.
however, invented a machines now at
the sParis Exhibition, which in a few
minutes completely sdemagnetizes' a
watch, leaving it as free in its move

M. de Bisschop has won a prize OF
LOCO francs, or $500, for small motor
suitable to useain families, ~ His engine
is worked by gas, and the operation
costs, at the prices current In Paris, two
cents. an hours for machines doing
work of ,36-17 foot7poundslper second,
five cents an hour for machines per
forming at the rate>of 1906 foot-pounds
|. per, second. Thessmaller machines are
sold for 500; the larger ones for $3.50.
The high price of toughened- glass
and the scare about its explosion in the
form of Fchimneys, tumblers; etc.,: has
hindered its progress Now.iM Mr. Sic
mems proposes to adaptit to lamp-posts,
water: mains, ,.etc. He claims that it is
stronger than iron castings, inperisha-
BILE and incorrodible, The cost per
pound is double that of iron, but the
specific gravity so smuch' less$ that the
average of goods will come ione-thusI
cheaper. -
The new metal of which it is pro
posed to construct pipes in which to lay
telegraph wires under is ade-
scribed as very light-only about one
sixth then weight Of iron-and,, being
composed almost entirely of pure gearA
bon, is indestructible, whether in the air /:
or under ground; it does not rust or
change by exposure, and is not affected
by heat or frost. The most important
characteristic claimed for it, however,
in connection with underground wires,
is, its being a perfect insulator.i a The
pipes of the metal need not, it is stated,
be buried very deep in the ground, as
they may be of semi-elastic character,
adjusting themselves to the. slight up
heaval and depression of the ground
through the action OF frost. "a
