If we come close to the edge where the rushes are growing, and look down through the clear water, we shall see some uncouth and clumsy black bugs crawling upon the bottom of the pond. They have six legs, and are covered with a coat of armor laid plate over plate. It looks hard and horny; and the insect himself has a dull, heavy way with him, and might be called very stupid were it not for his eagerness in catching and eating every little fly and mosquito that comes within his reach. His eyes grow fierce and almost bright; and he seizes with open mouth, and devours all day long, if he can find any thing suited to his taste. I am afraid you will think he is not very interesting, and will not care to make his acquaintance. But, let me tell you, something very wonderful is about to happen to him; and if you stay and watch patiently, you will see what I saw once, and have never forgotten. Here he is crawling in mud under the water this May morning: out over the pond shoot the flat water-boatmen, and the water-spiders dance and skip as if the pond were a floor of glass; while here and there skims a blue dragon-fly, with his fine, firm wings that look like the thinnest gauze, but are really wondrously strong for all their delicate appearance. The dull, black bug sees all these bright, agile insects; and, for the first time in his life, he feels discontented with his own low place in the mud. A longing creeps through him that is quite different from the customary longing for mosquitoes and flies. "I will creep up the stem of this rush," he thinks; "and perhaps, when I reach the surface of the water, I can dart like the little flat boatmen, or, better than all, shoot through the air like the blue-winged dragon-fly." But, as he crawls toilsomely up the slippery stem, the feeling that he has no wings like the dragon-fly makes him discouraged and almost despairing. At last, however, with much labor he has reached the surface, has crept out of the water, and, clinging to the green stem, feels the spring air and sunshine all about him. Now let him take passage with the boatmen, or ask some of the little spiders to dance. Why doesn't he begin to enjoy himself? Alas! see his sad disappointment. After all this toil, after passing some splendid chances of good breakfasts on the way up, and spending all his strength on this one exploit, he finds the fresh air suffocating him, and a most strange and terrible feeling coming over him, as his coat-of-mail, which until now was always kept wet, shrinks, and seems even cracking off while the warm air dries it. "Oh," thinks the poor bug, "I must die! It was folly in me to crawl up here. The mud and the water were good enough for my brothers, and good enough for me too, had I only known it; and now I am too weak, and feel too strangely, to attempt going down again the way I came up."
