fish adorns the hundred hooks! But to be a successful fisher you
must try, try again, and so they did. Hooks were rebaited and re- V -
set. The day was spent in procuring fresh bait, wandering along
the bank or taking a boat ride. Then the hooks are tried again and .

gr? Theories as to the age of the earth. in so far as they are based
upon facts at all, naturally fall under two heads :
p _ 1. Physical and astronomical.
li 2. Geological.
_ FirstThe physical and astronomical theories:
. (zz). The purely physical,based upon data relating to the rate at
which the earth is cooling off`, and thence to the time that has l
elapsed since it was in a molten state."Sir William Thompson.
l (b). Astronomical--Based upon data relating to the rate at which
tidal friction retards the rotation ot the earth, and thencs totime
. since the moon sepnatccl from itthe earth of course being molten C .
at the time.George Darwin. C
r (0). Mixed Physical and AstronomicalTaking into consideration E
tidal friction, earth cooling, and also sun cooling and contraction.- f
, V Tait and others.
(zz). Calculations based upon estimatxd total thickness of rock sed-
iments, and rate at which such sediments accumulate to-day along
shores and in secluded ocean basins.Haugl1ton, Wallace, Williams
l and others.
(Z2). Method (a) modified by the introduction of time ratios based
upon the relative thickness of rocks formed in the different geologi-
. cal ages.\\'alcott, Dana, Williams. Q
(c). Calculations based the rate of erosion since the ret1eat of the
