In truth, a fly is the most impertinent and indelicate thing in creation,--the very type and moral of human spirits with whom one occasionally meets, and who, perhaps, after an existence troublesome and vexatious to all with whom they come in contact, have been doomed to reappear in this congenial shape. Here is one intent upon alighting on my nose. In a room, now,--in a human habitation,--I could find in my conscience to put him to death; but here we have intruded upon his own domain, which he holds in common with all other children of earth and air; and we have no right to slay him on his own ground. Now we look about us more minutely, and observe that the acorn-cups of last year are strewn plentifully on the bank and on the path. There is always pleasure in examining an acorn-cup,--perhaps associated with fairy banquets, where they were said to compose the table-service. Here, too, are those balls which grow as excrescences on the leaves of the oak, and which young kittens love so well to play with, rolling them over the carpet. We see mosses, likewise, growing on the banks, in as great variety as the trees of the wood. And how strange is the gradual process with which we detect objects that are right before the eyes! Here now are whortleberries, ripe and black, growing actually within reach of my hand, yet unseen till this moment. Were we to sit here all day,--a week, a month, and doubtless a lifetime,--objects would thus still be presenting themselves as new, though there would seem to be no reason why we should not have detected them all at the first moment.
