Methinks that for about three weeks past the light under sides of the upper leaves of maples, swamp oak, etc., etc., have been permanently conspicuous, while in June to middle of July they were observable only when there was more wind than usual. As if, owing to the dry weather and heat, those leaves were permanently held up, like those of the hard-hack, etc., - various weeds and shrubs on dry land, - perhaps had risen in the night and had not vitality enough to fall again. Now, accordingly, I see the dark-green upper sides of the lower leaves alone, and various agreeable shades of green thence upward. Now is the season to observe these various shades, especially when the sun is low in the west.
