1 68 WATER-LtLIES 



flower spikes of blue and white respectively, 

 are useful in some places. On the water's 

 surface the floating moss {Azolla Carolintana), 

 the duckweeds (Lemna), and the salvinia 

 (5. natans) are interesting. 



Where the lawn dips to the water's edge 

 a clump of swamp rose mallows (Hibiscus 

 Moscheutos) will bloom. This is well known 

 as an ordinary garden plant. The great 

 open flowers, white with red centre, or pink, 

 are often five inches across. They bloom 

 very freely through the middle and late sum- 

 mer. Japanese iris, too, in all their multi- 

 plicity of splendour, flourish near the margin 

 of the pond. 



It would lead us too far to speak of the 

 riches that the borders of the pond will har- 

 bour. Only in passing can we glance at two 

 or three nooks beside our way. Here in a 

 little bay a stately group of cat-tails (Typha), 

 narrow-leaved and broad, is waving. Be- 

 hind them a bushy brake of ferns (Pteris and 

 Woodwardia), willows and the swamp magno- 

 lia (M. glauca) leads on into the woodland.
