mean this It may have been directed little toward
or little from the observer in which case 1t would DO
longer There vas faint srsA% 9sint running tbat

this direction there were two streamers ndGatng
good instance OF how people will disagree observed
myself Colorado and had right by my size an as
as the eclipse over said to him: " Now, mat
should be mainly at right angles. to what i.
usually u.s. the main streamers running OUT tows. ra
sh Tsamer said ho STe you thinking of
Not at all The main streamers ran east and west NOT
north and south at all didn't see any running norm
this directon did not SEQ the streamers running IA
ina luminosity ot aid out and west but
there other bright and sharply defined streaners
in the Hh this sp bright
enough to be seen by the eye Inc ssreaners 1eto
the direction Of the others and be entangled with
them, almost like basket-work.

to make any photographs OF the corona wa, was
with an exposure OF something like fifty or sixty Sec
ond the clock Of the telescope 0eng ae Pr nba
graph did not show the corona at any one moment p.
showed It for the whole duration OF the ecpsea sort OF
summing up OF all the appearance of the corona during
the whole ecpse so the next time they tried to get
photograph with shorter exposure 49,,
Now we will pass the subject OF the moon, which
makes tho eclipse; I don't need to tel you
u.s. travelling around the earth once month and
month is 81 days hours IL seconds and 545 1,00Oth
of n second oug What mean by telling you just how
many thousandhs OF secsnd long Is 10 to insist that
know something certainly about hundreths OF sec
ond and perhaps thousandths You may ask me how
nd that out accurately It s done by comparing
ecllpses of old times with modern eciges 20 back to
Il was going TO say before the hood-but not
quite 50 long ago as that but 1000 years years
Before tho Christian era, and find on the bricks
OF Babylon and Nneyeh records OF the old ecllpses
We compare those with modern ecpses and as we know
nearly those dates, find by comparing those
remote dates very close connection. 20 when gave
the month n accurately / did, / did not say much
than know. The month that mentioned was
what Ia known the sderal month and not the solar
month. The Ia $4,000 miles away and II Is 2l63
miles IN diameter. In some respects Ia globe very
from the earth 1t Ia only about cneortyninh OF the
earhs bulk and has about onefOurteenth part OF the
earhs surface and by comparing the tides that IL pro-
duces with those which the produces We arc able TO
compare its weight with that OF the EARTH IL a more
difficult TO ind the OF the moon compared Win inc
earth than 10 s TO lud the mass OF the planet Mars
compared with the earth We have to take
cOurse that Is very like going from New-iOrk TO
Jersey City By OF Albany We have to compare the
moons with the and the suns mass Win the
EARTH and compare them with each other II Ia only
IL about three-hfths that OF the earth. Through
and through IL ia about as heavy as
the rock that makes the surface or the earth When we
examine It with the telescope We find It's surface s
broken up and instead OF examining with the telescope
we may take photographs. New-lork, think on the
whole, maintains the prominence in lunar photography
The largest photograph made, nearly four feet In
diameter, made by Prof. Henry Draper In 1860 OF
1867.
