LENGTH OI The DAYS.
Difference Between the Star Day
. and the Sun Day.
1T IS GREATEST IN WINTER.

II IS GREATEST IN WINTER.
Why the Difference Occurs ard How
II May Be Observed Oddly Enough
the Shortest Day In the Year Is
Really the Longest Day Ia Time.
How long, after all, is day2 The
biographies say that 1t is the time re-
quired for the earth to turn once on
Its axis, that it measures twenty-four
hours by the clock and that q fraction
more than 1855 of them are to be found
in a year.
b It is a good plan when one, reads
anything in a book to test it when he
can for himself. We want to see just
how long 1t takes the earth to turn
over once. Let us take any one Of
the fixed stars that chances to be in
line with some convenient point and,
watch In hand, notice the precise mo-.
ment at which the star touches, let us
say a particular tree, branch or stee-
pie on the. horizon line. Tf on the next
evening we stand at precisely the same
spfo'tt ana slgnI tne same star again u
iine Win the same NE, point as before,
Enen we snaii Know tnat the eaEtn mas
turned on its axis just once;
Curiously enough, however, we shall
discover, If this is done carefully, that,
