NOVEMBER TO SEE
THREE SPECTACULAR.
MET:EOR|C SWARMS.
LATTER HALF OF THIS MONTH
WILL BE CROWDED WITH
BEAUTIFUL SHOWERS IN SKIES
o, ARE PARTS OF COMETS.

Meteors generally appear in great
err numbers in the fall than at any
other time of year and the latter
half of November is u particularly
favorably time TO watch for meteoriC
displays
Three periodic swarms of meteors
are scheduled to appear yearly in
November These are the Taurds
named In each Instance for the con
stellation in which the radiant point
is located. This is the point from
members OF the swarm appear to
radiate and 1t shows the general di.
rection In space from which the met.
eors are coming
The Taurids are likely to apnear
any time during November, but their
greatest display Is scheduled for No
yembcr II.
The Leonids appear any time be.
tween November and 20, but are
seen In greatest numbers on Novem.
Der Ia and 10 They follow in the
orbit OF Temples Comet of 1866,
which has period OF SO years.
The Andromedes appear between
November 20 and 30, but their great.
est DISPLAY occurs between November
20 and %. 1t is believed that the
Andromedes are the remains OF Bic
las Lost Comet and for the reason
they are often called Bielids. They
appear In exceptionally great mum
bers every thirteen years. Remark
able displays of Bielids took place in
1872 1885 and 1898
When swarm of meteors is quite
evenly distributed around its orbit
the displays are equally great every
year and occur at the time of the
earth's path intersects the path of the
swarm. When the meteors are
punched" at certain points in the
orbit as is the case with the Leonids
and Andromedes. exceptionally great
displays occur in certain years
Dense showers of Leonids occurred
in 1888 and 1866 and to a less degree
between 1898 and 1901.
The Leonids appear in the early
morning hours before sunrise and SC
the earth meets them head on" As
result, they are remarkable for
their rapid flights as well as for their
long. vivid trails and intense blue or
greenish light
n Some in Early Evening.
The Andromedes or Belids, on the
other hand, appear in the early eve
ming hours and so have to overtake
the earth in its orbit Consequently
they have a slow motion relative tc
the earth. They are reddish in color
with short trails that soon dissap.
pear.
The Taurids come midway between
the Leonids and Bielids. being visible
around midnight.
- On any clear evening when tn
moon Is absent one may usually see |
two or three meteors in the course
OF an evening, but if a dozen or 81
should be seen in a single hour onr
may be assured the earth is passinf |
thru swarm Of considerable densi |
ty. Since the field of view of a sin |
gle observer is necessarily limited |
he sees only small portion of tn |
total number that enters the earthy |
Meteors or shooting stars travelini
In swarms are believed to be in ev
cry instance the result of the disin
tegration Of comets That is, they
are mere cometary dust They are
distinct in origin and nature
from the fireballs or meteorites that
strike the earth's surface and whose
advent is usually heralded with 81
flash of light and deafen
ing explosion. Only in one or two
instances has a meteorite appeared
with a swarm of meteors
The Rose Diamond.
One often hears Of rose diamond
The stone Is not different in kind
from any other diamond the name

A rose diamond is one that has fiat
