SCIENCE AND INDUSTRY.

1t is said that if the earth's atnos-
| phere extended to a height of 700 miles
the SUMS heat and rays could never
| penetrate it, and we would freeze to
| death while wrapped in darkness
| blacker than the blackest midnight.
The chief element in the compost
|. ton of n tear is water, but with
water is associated minute proportions
of salt, soda, phosphate of lime, phos-
| phate of soda and mucus, and when
seen under the microscope tear after
evaporation looks like a very small fish
bone, owing to the salines forming
themselves into heightened cross-lines
| in England the acreage and crop of
| hops is large. In the Worcester district
| it is so, 900 to So, 900 hundred weight.
There is a great difference in the hop
acre and the statute acre. Five statute
acres are equal to eight hop acres. In
many parts, great difficulty in harvest
ing and securing the crops has been ex.
perienced this year.
Ventura county, Cal, is the most
prolific bean-growing section in the
world. One ranch of 2, 200 acres has
produced 1 ,03O tons of Lima beans this
| year. 1t took 81, 900 sacks to hold the
crcp, and they will fill about 103 cars,
on an average of ten tons to the car.
This will make eight or nine solid trains
of beans. But this is only from one
ranch. The railroad company expects
to handle 1,50O carloads of beans on the
Ventura division this year.
Work has been already commenced
on the big mill at Fall River, Mass,
which is to supply the American Print
ing Company. The Hargraves Company
is preparing plans for its new $4,000
spindle mill, and the Kerr thread mill
is to be enlarged to twice its present
size. The Durfee and King Philip mill
will start work on its weaving sheds as
soon as the weather will permit. These
new concerns will add valuation OF
So, 500. 600 to the city and will give en-
ployment to 2, 500 persons.
in Germany wood with mirror
polish is coming into use for orna-
mental purposes in place of metal. The
wood is first submitted to bath of
caustic alkali for two or three days at a
temperature of about IT'S degrees Fahr-
enheit, then dipped into hydrosulphate
of calcium for twenty-four to twenty
nine hours, after which a concentrated
solution of sulphur is added After an
other dip in an acetate of lead solution,
at about ten degrees, shining metallic
surface is given by polishing, when dry,
with lead, tin or zinc.
The first railway built by George
Stephenson, opened in 1922, was eight
miles long, and was SO successful that
in the next year he was appointed engi-
neer of the railway recently authorized
to be constructed between Stockton and
Darlington, and IN 1925 of the Liverpool
and Manchester lines which was com.
menced in 1926. At this time the best
engineers held that the use of locomo
tives was practically impossible, and
that safety and speed could be attained
only by stationary engines placed al
short intervals along the line. ...
1t is not generally known that there
is medicine called nitro-glycerine
which is as powerful in stimulating the
organs as the explosive of the same
, name is in tearing rocks and trees Il
is used by doctors only when their pa
, tient is at the point of death to revive
the hearts action. 1t operates in thi!
manner: There is certain nerve
which, in healthy mans body, keep:
the heart from beating too fast-acts al
sort of brake-but when the body i
diseased and the heart movement slug
, gish, the nerve tends to stop the heart
I action. The nitro-glycerine paralyze
this nerve and disencumbers the heart

} --Geologists divide caves and cavern
!: into five distinct classes. First, tn
caverns in limestone rock excavated b,
T streams which find their way beneatl
\ the surface. Second, the channels ant
chambers followed out by the water
of hot springs on their way from th
: earth to the surface. Third, the Sc;
caves and grottos, which are forme'
| where the battering surges have worl
t away into the shore cliffs along the lin
J of some softer part of the rocks. Fourth
| the cavities curiously formed where
lava stream has solidifed upon the sur
face. Fifth and lastly, we have tn
} riffs formed in the rocks which hav
l been rent by the mountain-buildin
/ forces, where the walls on either sid
of the break have been pulled apar
. from each other, leaving very dee
and long, but usually narrow, fssure
In one or another of these groups ma
be placed all the known cavities whic
occur beneath the earth's surfac,
These, of course, may be subdivide
! into many sub-classes.--S Louis Rt
