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. _ 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.
