THE caoar. 29 off to the river to see its luck. Yes, and how lucky! But one small · fish adorns the hundred hooks! But to be a successful fisher you must try, try again, and so they did.

Then comes the feast, f and off for home we go. C K Thus have been spent a few days on the banks of the Mississippi. (To be continued.) - GEOLOGIC TIME. la 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. ·_ First—The 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 it——the earth of course being molten C . at the time.——George Darwin. C r (0). Mixed Physical and Astronomical—Taking into consideration E tidal friction, earth cooling, and also sun cooling and contraction.- f , V Tait and others. Second--Geological 1 (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.
