generally admitted now to be the result of a curious and extremely
minute vegetable growth, which spreads not only over its surface, but
penetrates into it sometimes to a depth of several feet. The earlier
navigators who discovered it, and first told the astonished world that
the substance which they had been accustomed to associate with the idea
of the purest and most radiant whiteness had been seen by them lying
_red_ upon the ground, attributed the phenomenon to innumerable
multitudes of minute creatures belonging to the order _Radiata_; but the
discovery of red snow among the central Alps of Europe, and in the
Pyrenees, and on the mountains of Norway, where _marine_ animalcula
could not exist, effectually overturned this idea. The colouring matter
has now been ascertained to result from plants belonging to the order
called _Algae_, which have a remarkable degree of vitality, and possess
the power, to an amazing extent, of growing and spreading with rapidity
even over such an ungenial soil as the Arctic snow.

While Singleton was examining the red snow, and vainly endeavouring to
ascertain the nature of the minute specks of matter by which it was
coloured, Fred continued to gaze with a look of increasing earnestness
towards the tall column, around which a bank of fog was spreading, and
partially concealing it from view. At length he attracted the attention
of his companion towards it.

"I say, I'm half inclined to believe that yon is no work of nature, but
a monument set up to attract the attention of ships. Don't you think
so?"

Singleton regarded the object in question for some time. "I don't think
so, Fred; it is larger than you suppose, for the fog-bank deceives us.
But let us go and see; it cannot be far off."
