GLACIER ICE.
Glacier ice is not like the solid blue ice on the surface of the water, but consists of granules joined together by an intricate network of capillary water, filled fissures. In exposed sections and upon the surface of the ice can be observed “veined” or “banded” structure veins of a denser blue color alternating with those of a lighter shade containing air bubbles. The cause of this peculiar structure has been the subject of much theorizing among investigators, but hitherto the greatest authorities consider that the explanation of the phenomenon is yet wanting.—Goldthwaite’s Geographical Magazine.
