in Thoreau’s Journal:

Lupines, their pods and seeds. First, the profusion of color, spikes of flowers rising above and prevailing over the leaves; then the variety in different clumps, rose? purple, blue, and white; then the handsome palmate leaf, made to hold dews.

June 11, 1851:  No one to my knowledge, has observed the minute differences in the seasons. Hardly two nights are alike. The rocks do not feel warm to-night, for the air is warmest; nor does the sand particularly. A book of the seasons, each page of which should be written out-of-doors, or in its own locality wherever it may be.
