On the top of the tower were some projecting growths, that kept up the similitude of broken battlements.
Making a dark green background were the lower stems of the reeds that rustled above the water, and in the open space between the water-weeds and the margin of the pond rose the three spiral stalks of a large flowering nymphœa, two of them throwing out their flat glossy leaves, and the third a beautiful pale blue lily, that lay like a gleaming star upon the surface of a crystal mirror. Besides the alge that I have described, there were others at the bottom of the pool, with their lobulated and dentated leaves, rivalling ferns in the gracefulness of their form.
