When the three had finished with it, the aquarium really looked rather nice, and, if you stooped down and looked sideways through the glass, like a real aquarium.

Kathleen took some clinkers from the back of the rockery—“where they won’t show,” she said—and Mavis induced these to stand up like an arch in the middle of the glassy square. Tufts of long grass, rather sparingly arranged, looked not unlike waterweed. Bernard begged from the cook some of the fine silver sand which she uses to scrub the kitchen tables and dressers with, and Mavis cut the thread of the Australian shell necklace that Uncle Robert sent her last Christmas, so that there should be real, shimmery, silvery shells on the sand. (This was rather self-sacrificing of her, because she knew she would have to put them all back again on their string, and you know what a bother shells are to thread.) They shone delightfully through the glass. But the great triumph was the sea anemones—pink and red and yellow—clinging to the rocky arch just as though they were growing there.

“Oh, lovely, lovely,” Kathleen cried, as Mavis fixed the last delicate flesh-tinted crown. “Come and look, France.”

“Not yet,” said Mavis, in a great hurry, and she tied the thread of the necklace round a tin goldfish (out of the box with the duck and the boat and the mackerel and the lobster and the magnet that makes them all move about—you know) and hung it from the middle of the arch. It looked just as though it were swimming—you hardly noticed the thread at all.

Now, France,” she called. And Francis came slowly with his thumb in The Water Babies. It was nearly dark by now, but Mavis had lighted the four dollhouse candles in the gilt candlesticks and set them on the table around the aquarium.

“Look through the side,” she said; “isn’t it ripping?”

“Why,” said Francis slowly, “you’ve got water in it—and real anemones! Where on earth...?”

“Not real,” said Mavis. “I wish they were; they’re only dahlias. But it does look pretty, doesn’t it?”

“It’s like Fairyland,” said Kathleen, and Bernard added, “I am glad you bought it.”

“It just shows what it will be like when we do get the sea creatures,” said Mavis. “Oh, Francis, you do like it, don’t you?”
