Clouds tend to form around storms

perature is high in front of storms and

storm.
The marsh lands back of Atlantic
CITY are to be filled in and reclaimed.
The dredgings of three hydraulic steam
dredging machines in the inlet are to be
forced through pipe mile and quar-
ter in length to the main land. The pipe
is to be supported by scows or pom
toons. The centrifugal pumps are to
have a capacity of ten cubic yards a
minute in stiff blue clay, and larger
capacity in lighter material from the
bottom of the inlet.
The interesting claim is made for
Arkansas of furnishing the finest whet-
stones of any to be found in the United
States for the sharpening of fne-edged

| BILE beds of the substance called novoca'
lite. or what is scientifically known as
an altered schist; this means a deposit
of a finty nature, usually com blned
with limestone. the rock thus produced
being changed in such a manner mole
cularly, by processes not altogether un'

Humboldt estimated that Asis
stands at an average height of !. .150 fee
above the level of the ocean: Soutl
America, 1,13O; North America, 750; Eu
rope 670 feet. The average height o
all the land above sea level-omittin!
Africa and Australia, which are mostl.
south of the equator-is about 800 feet
The landed surface of the nertherl
hemisphere is about 44,0O0,O 900 squar
miles: that of the southern hemispher
about $4,000, 600 to 10000, 900 squar
miles, leaving a difference of, say %,
900. 900 square miles of land of an aver
age height of 92O feet above the Sc
level.
An ingenious kind of stop motio
for cording engines is being introduced
In this arrangement the shaft of tn
upper calendar roller is prolonged be
yond it's bearing for a short distance an
q worm affixed to the end gearing int
a worm wheel mounted on a stud a
tached to a bracket on the framing tn
: wheel also having affixed to its face
| pin which engages with lever, the la
ter in turn acting upon one end {
: another lever. The other end of tn
: last named lever is bent in such a maj
ner as to pass under catch pivoted
: one side of the doffer lever, the latte
, being supported in working position b
: the catch.
