1T is said that il the earth's atmos-
phere extended to a height of 700 miles
the suns heat and rays could never
penetrate it, and we would freeze to
death while wrapped in darkness

The chief element in the compost
ton of 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 CROSSINGS
in England the acreage and crop OF
hops is large. In the Worcester district
il is so, 600 to IS, 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-
pcrienced this year.
Ventura county, Cal, is the most
| prolific bean-growing section in the
world One ranch of 1900 acres has
produced 1880 tons of Lima beans this
year. 1t took 81. 900 sacks to hold the
crop, 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 800 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

is preparing plans for its new $4,000

size. The Durfee and King Philip mill
will start work on its weaving sheds rs
soon as the weather will permit. These
new concerns will add a valuation of

| 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 at
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 1t
is used by doctors only when their pa
tient is at the point of death to revive
the hearts action. 1t operates in this
manner: There is a certain nerve
which, in healthy mans body, keeps
the heart from beating too fast-acts as
a sort of brake-but when the body is
diseased and the heart movement slug
gish. the nerve tends to stop the hearts
action. The nitro-glycerine paralyzes
this nerve and disencumbers the heart

--Geologists divide caves and caverns
into five distinct classes First, the
caverns in limestone rock excavated by
streams which find their way beneath
the surface. Second, the channels and
chambers followed out by the waters
of hot springs on their way from the
earth to the surface Third. the sea
caves and grottos, which are formed
where the battering surges have worn
away into the shore cliffs along the line
of some softer part of the rocks Fourth,
the cavities curiously formed where a
lava stream has solicited upon the sur
face. Fifth and lastly, we have the
riffs formed in the rocks which have
been rent by the mountain-building
forces, where the walls on either eide
of the break have been pulled apart
from each other, leaving a very deep
and long, but usually narrow, assure.
In one or another of these groups may
be placed all the known cavities which
occur beneath the earth's surface.
These, of course, may be subdivided
into many sub-classes-St Louis Re.
