As One carried beyond his depth for the first time into the waters of ocean, and struggling shorewards, touches but now and then the yellow sands, with every heaving wave again to be set afloat, feels a delight when he plants his foot solidly on the sands, and wades through shallower water to the shore, so do we after our almost footless path through the wide waste of water of the first age, hail with delight our firmer footing on the spreading shores of this next great geological period.
