Notes
March Seventh
Clinging to the cliffs and rocks in the forests, the dark green leathery leaves of the polypody fern are nearly as fresh and green as when first snowed under. Hunt among the clusters until you find a fertile frond, then examine the back of it and see how closely together the spores are placed.
March Eighth
We will awaken some morning to find that during the night the song sparrows have arrived from the South; not all of them, to be sure, but just a few that are anxious to push North and begin nesting. All winter their merry song has been hushed, but now it gushes forth, not to stop again until the molting season in August.
March Ninth
A porcupine should never be called a hedgehog. The hedgehog, an insectivorous animal, inhabiting Europe, is not found in the Western Hemisphere. It rolls itself into a ball when attacked, and the spines, which do not come out, are shorter, duller, and less formidable than those of the porcupine.
