... I have found in midwinter, in this high latitude of 78 deg.
50', the surface so nearly moist as to be friable to the touch; and upon
the ice-floes, commencing with a surface-temperature of-30 deg., I found
at two feet deep a temperature of-8 deg., at four feet + 2 deg., and at eight
feet + 26 deg.. ... The glacier which we became so familiar with afterwards
at Etah yields an uninterrupted stream throughout the year." And he
afterwards shows that even the varying texture and quality of the snow
deposited during the earlier and later portions of the Arctic winter
have their special adaptations to the welfare of the vegetation they
protect.
The process of crystallization seems a microcosm of the universe.
Radiata, mollusca, feathers, flowers, ferns, mosses, palms, pines,
grain-fields, leaves of cedar, chestnut, elm, acanthus: these and
multitudes of other objects are figured on your frosty window; on
sixteen different panes I have counted sixteen patterns strikingly
distinct, and it appeared like a show-case for the globe. What can seem
remoter relatives than the star, the starfish, the star-flower, and the
starry snow-flake which clings this moment to your sleeve?--yet some
philosophers hold that one day their law of existence will be found
precisely the same. The connection with the primeval star, especially,
seems far and fanciful enough, but there are yet unexplored affinities
between light and crystallization: some crystals have a tendency to grow
toward the light, and others develop electricity and give out flashes of
light during their formation.
