Thoreau writes in his journal:
The branches and taller greasses were covered with a wonderful ice-foliage, answering leaf for leaf to their summer dress. The centre, diverging, and even more minute fibres were perfectly distinct and the edges regularly indented.
These leaves were on the side of the twig or stubble opposite to the sun (when it was not bent toward the east), meeting it for the most part at right angles, and there were others standing out at all possible angles upon these, and upon one another.
It struck me that these ghost leaves and the green ones whose forms they assume were the creatures of the same law. It could not be in obedience to two several laws that the vegetable juices swelled gradually into the perfect leaf on the one hand, and the crystalline particles trooped to their standard in the same admirable order on the other.
The river, viewed from the bank above, appeared of a yellowish-green color, but on a nearer approach this phenomenon vanished; and yet the landscape was covered with snow.
