Thoreau writes in his journal:
As further confirmation of the fact that vegetation is a kind of crystallization. I observe that upon the edge of the melting frost on the windows, Jack is playing singular freaks,—now bundling together his needle-shaped leaves so as to resemble fields waving with grain, or shocks of wheat rising here and there from the stubble. On one side the vegetation of the torrid zone is presented you,—high-towering palms, and widespread banyans, such as we see in pictures of Oriental scenery; on the other are arctic pines, stiff-frozen, with branches downcast, like the arms of tender men in frosty weather. In some instances the panes are covered with little feathery flocks, where the particles radiate from a common centre, the number of radii varying from three to seven or eight. The crystalline particles are partial to the creases and flaws in the glass, and, when these extend from sash to sash, form complete hedgerows, or miniature watercourses, where dense masses of crystal foliage “high over-arched imbower.”
