But hark! there is the whistle of the locomotive,--the long shriek, heard above all other harshness; for the space of a mile cannot mollify it into harmony. It tells a story of busy men, citizens from the hot street, who have come to spend a day in a country village,--men of business,--in short, of all unquietness; and no wonder that it gives such a startling scream, since it brings the noisy world into the midst of our slumberous peace. As our thoughts repose again after this interruption, we find ourselves gazing up at the leaves, and comparing their different aspects,--the beautiful diversity of green, as the sun is diffused through them as a medium, or reflected from their glossy surface. We see, too, here and there, dead, leafless branches, which we had no more been aware of before than if they had assumed this old and dry decay since we sat down upon the bank. Look at our feet; and here, likewise, are objects as good as new. There are two little round, white fungi, which probably sprung from the ground in the course of last night,--curious productions, of the mushroom tribe, and which by and by will be those small things with smoke in them which children call puff-balls. Is there nothing else? Yes; here is a whole colony of little ant-hills,--a real village of them. They are round hillocks, formed of minute particles of gravel, with an entrance in the centre, and through some of them blades of grass or small shrubs have sprouted up, producing an effect not unlike trees that overshadow a homestead. Here is a type of domestic industry,--perhaps, too, something of municipal institutions,--perhaps likewise--who knows?--the very model of a community, which Fourierites and others are stumbling in pursuit of. Possibly the student of such philosophies should go to the ant, and find that Nature has given him his lesson there. Meantime, like a malevolent genius, I drop a few grains of sand into the entrance of one of these dwellings, and thus quite obliterate it. And behold, here comes one of the inhabitants, who has been abroad upon some public or private business, or perhaps to enjoy a fantastic walk, and cannot any longer find his own door. What surprise, what hurry, what confusion of mind are expressed in all his movements! How inexplicable to him must be the agency that has effected this mischief! The incident will probably be long remembered in the annals of the ant-colony, and be talked of in the winter days, when they are making merry over their hoarded provisions. But now it is time to move. The sun has shifted his position, and has found a vacant space through the branches, by means of which he levels his rays full upon my head. Yet now, as I arise, a cloud has come across him, and makes everything gently sombre in an instant. Many clouds, voluminous and heavy, are scattered about the sky, like the shattered ruins of a dreamer's Utopia; but I will not send my thoughts thitherward now, nor take one of them into my present observations.
