Every year a considerable number of people, including geological students, go to the Jlocraki beach to see the spherical boulders, which resemble cannon balls (save Hie “Southland Times”). The balls vary in diameter from six feet to nine inches. Their colour is bluish grey, and. they are presumed to have been washed, by the action of the sea out of the adjacent beds of amorphous blue clay, ot which the overhanging cliffs are comprised. The balls are- composed of the same material as the ctay-beds, with the difference that they are intersected, with veins of carbonate of lime, radiating from the nucleus to all parts of .tho exterior. Under a natural process induced by chemical affinity, the. formation and augmentation of these veins of carbonate of lime appear to have been the means of constructing the balls.
