in Thoreau’s Journal:

Yesterday when the blossoms of the Golden Willow began to fall—the blossoms of the apple began to open….It is a splendid day—so clear & bright & fresh—the warmth of the air & the bright tender verdure putting forth on all sides make an impression of luxuriance & genialness—so perfectly fresh & uncankered. A sweet scent fills the air from the expanding leafets or some other source—  The earth is all fragrant as one flower & bobolinks tinkle in the air. Nature is perfectly genial to man.
