is who has the last chance always has the

will rise the highest in summer and fall
the lowest in winter is a joy forever "
N The truth is that an absolutely accurate

20 cu.acy of this instrument depends en-
lie tirely on the care given in its manufact-
!. ure. The evenness of the bore and the
- size of the bulb are what determine the
n, accuracy of any thermometer
NJ If the tube of thermometer contains
=. air the mercury frequently divides Itself
re- into two or three slender threads, each
IL separated from the other, and thus the
a instrument is rendered useless until the
of threads are made to unite. The best way
