Yet they seemed to assume a sort of fantastic kindred with the objects
to which they adhered: thus, on the leaves of spruce-trees and on
delicate lichens they seemed like reduplications of the original growth,
and they made the broad, fiat leaves of the arbor-vitae fully twice as
wide as before. But this fringe was always on one side only, except
when gathered upon dangling fragments of spider's web, or bits of stray
thread: these they entirely encircled, probably because these objects
had twirled in the light wind while the crystals were forming. Singular
disguises were produced: a bit of ragged rope appeared a piece of
twisted lace-work; a knot-hole in a board was adorned with a deep
antechamber of snowy wreaths; and the frozen body of a hairy caterpillar
became its own well-plumed hearse. The most peculiar circumstance was
the fact that single flakes never showed any regular crystallization:
the magic was in the combination; the under sides of rails and boards
exhibited it as unequivocally as the upper sides, indicating that the
phenomenon was created in the lower atmosphere, and was more akin to
frost than snow; and yet the largest snow-banks were composed of nothing
else, and seemed like heaps of blanched iron-filings.
Interesting observations have been made on the relations between ice and
snow. The difference seems to lie only in the more or less compacted
arrangement of the frozen particles.
