That was Monday, and Smalltown moved with the monotony of the old hall clock’s pendulum until Sunday morning. Then the quiet blacksmith took his seat in church near the door and sat through the service. In due course the sermon of the past half-century, with variations, was preached, and ended with the usual peroration, “Brethren, is this not true?” With the asking of that question Smalltown was shaken to its foundations, for the blacksmith quickly shouted, “No!” and straightway retired. That minister had no faith in the skill of the blacksmith; the latter placed no confidence in the preacher’s logic. I do not defend the blacksmith, but, somehow, when I heard the story, I was otherwise than shocked. There is a bit of harshness in it, perhaps, but the remark must needs be made: Pin not too much faith upon defective memory; and it may be rightfully added, there is nothing but reasonableness in the suggestion that he who presumes to know all things is no safe authority upon any. The Night-Side of Nature. Not long since I checked the flow of a diminutive brook that barely trickled over a most tortuous course, and during midsummer was often a thing forgotten. By building a dam I raised a shallow pond about two hundred feet square, and nowhere more than eighteen inches deep, save at its outlet. Here are now growing beautiful water-lilies—pink, yellow, blue, and white—the stately lotus, and many a pretty aquatic plant from foreign lands. Of these I have nothing now to say, except incidentally, but a good deal concerning the remarkable zoölogical features of this artificial pond in the corner of an exposed upland field. I am quite sure that the most skillful hunter would have found no game had he scoured this and the adjoining fields, even with trained dogs; no trapper would have deigned to set a snare anywhere about the place, and the naturalist would have considered the outlook most unpromising. As in every farming district, here were acres of corn-fields, wheat-fields, truck-patch, and pasture, and nothing but grass or growing crops to relieve the monotony of the landscape. Every vestige of wildness has long since been improved off the face of this region, and grasshoppers, mice, and field-sparrows constitute the fauna. That is, apparently so; and how readily we underrate the merits of the so-called commonplace in nature! The truth is, every inch of these unsuggestive fields has ever been and is familiar ground to hosts of cunning creatures, or how else could the pond that was formed in a few days have become tenanted as it now is? The remarkable promptness with which every nook and corner was occupied by some water-loving animal almost the very day the pond was formed shows how much is overlooked if we familiarize ourselves only with the events of the day, and ignore, as young naturalists are all too apt to do, the night-side of nature.
