It was warm by the pool and utterly still. The sun, flushed and tired with his daily work, seemed to rest a moment on the rim of the dunes, for a breathing spell before diving under. The smooth water reflected, almost perfectly, the flaming face of the sun. The leaves of the beech tree which hung over the pond took advantage of the stillness to look at themselves attentively, in the mirror-like water. The solitary heron, standing on one foot between the broad leaves of a water-lily, forgot that he had come out to catch frogs, and, deep in thought, was gazing along his nose.

Then came Johannes to the grass plot, to see the cloud-grotto. Plump! plump! sprang the frogs from the bank. The mirror was all rippled, the image of the sun was broken up into broad bands, and the beech leaves rustled angrily, for they had not yet viewed themselves long enough.

Fastened to the bare roots of a beech tree lay a little old boat. Johannes had been strictly forbidden to get into it; but, oh, how strong the temptation was this evening! The clouds had already taken the semblance of a wondrous portal, behind which the sun would soon sink to rest. Glittering ranks of clouds ranged themselves at the sides, like a golden-armored life-guard. The face of the water reflected the glow, and red rays darted through the reeds like arrows.

Slowly, Johannes loosened the boat-rope from the roots. He would drift there, in the midst of the splendor. Presto had already sprung into the boat, and before his master intended it the reeds moved apart, and away they both drifted toward the evening sun.

Johannes lay in the bow, and gazed into the depths of the light-grotto. Wings! thought he. Wings now, and away I would fly!

The sun had disappeared, but the clouds were all aglow. In the east the sky was deep blue. A row of willows stood along the bank, their small, pale leaves thrust motionlessly out into the still air. They looked like exquisite, pale-green lace against the sombre background.

Hark! What was that? It darted and whizzed like a gust of wind cutting a sharp furrow in the face of the water. It came from the dunes—from the grotto in the clouds!

When Johannes looked round, a big, blue dragon-fly sat on the edge of the boat. He had never seen one so large. It rested there, but its wings kept quivering in a wide circle. It seemed to Johannes that the tips of its wings made a luminous ring.

That must be a fire dragon-fly, he thought—a rare thing.

The ring grew larger and larger, and the wings whirled so fast that Johannes could see nothing but a haze. And little by little, from out this haze, he saw the shining of two dark eyes; and a light, frail form in a garment of delicate blue sat in the place of the dragon-fly. A wreath of white wind-flowers rested upon the fair hair, and at the shoulders were gauzy wings which shimmered in a thousand hues, like a soap bubble.
