it's annual product will be equal in |

-Leuwenhock has computed that !
TO- 900 threads of the web of full-grown !
spider are not larger than single hair
of mans beard. He calculates that
when young spiders begin to spin, 400
of their threads are not larger than one
from a full-sized insect If this be "a
fact, q, 600, 900 webs of young spider
are not as large as single hair from a
mans face.
Lord Salisbury, in recent lecture
before the Chemical society of London,
made the following unique classified
ton of the three chief sciences: "Astron-
omy" said his lordship, lis, in II great
measure, the science of things as they
probably are; geology is the science of
things as they probably were; chemis'
try is the science of things as they are
at present"
Most of the picking of hops on the
Pacific slope is done by Indians, who
come from all over the adjacent terri
| tory and many even from Alaska. Old
mariners are astounded by the daring
of the Siwashes in coming so many hun
dreds of miles down the dangerous
coast in their frail birch bark canoes.
The Indians bring their families and all
their belongings with them.
"A great steel railroad bridge is to
be erected over the Columbia river at
Vancouver, Wash. 1t is to be G, 900 feet
long and double declked, with roadways
on top for teams. The draw pier will
give an opening of 200 feet for vessels
to pass. In order to get foundation
for the pneumatic piers it will be neces-
sary, on account of the sandy soil, to go
down eighty feet below low water
The most extensive salt mine is in
Wieliezka, near Cracow, Austro-Hun-
gary. For six hundred years it has
been constantly worked, and from it
55, 900 tons of salt are annually taken.
The mass of salt in it is estimated to be
five hundred miles long, twenty miles
broad, and 200 feet in depth. Its col
lective galleries are fully thirty miles
in length, and its lower level contains
streets and houses, making it a COM
plete underground village.-Indianapo

1t is announced that we are to have
an American smoleless powder Prof.
, Charles e. Monroe, government chemist
, at the naval torpedo station at New
, port, has invented powder that is prac.
, tically without smoke and that has been
, found to work admirably in tests with
the new three and six FOUNDER rapid
fire guns. Careful attention is to be
paid to developing and perfecting this
compound, and it is confidently asserted
that it will be equally available for
small arms-N. Y. Press.
!, M. Vignon's new method of analyD
sis applicable to industrial waters
= which have to undergo chemical puri
fcation, leads him to some interesting
conclusions as published in the Moui
teur Scientifque. Among the state
ments thus made is the valuable one
that, in order to determine the element:
of publication, or the anti-incrustatior
agents, it is sufficient to determine the
free or the half-com bined carbonic acid
and to determine the quantity of solu
:. BILE salts of calcium and magnesium
into carbonates which are chemically
a neutral.
"A man lives in Turkaiin, in the
province of Livonia, who can cure the
;, worst cases of hydrophobia. His medi
y cine for the disease consists of bugs O.
\ the size of FREELY, which he gather!
in the month of May in sandy places
" He keeps them in clean bottles until
they become perfectly dry and shriv
elled to the size of the small com
mon fly. Only one desc of two sucf
: bugs k7eaded in bread is sufficient tt
: cure the worst case of hydrophobia
. When the patient takes the dose hi
y temperature begins to rise. In abou
