AQUATIC ADJUNCTS OF A ROCK GARDEN. 113 



water-supply which is needed from this source secured 

 by April, all anxiety may be at an end for the year, as 

 the summer wastage is so slight as to be easily made 

 up by occasional showers. 



Assuming that the pool is to be given up to 

 Nymphaeas they may be planted in spring. In pre- 

 ference to putting them indiscriminately about the 

 pool I advise planting in a ring, the clumps a yard 

 apart, and half a yard or so from the sides. This 

 i arrangement provides plenty of room for each plant. 

 I The leaves wiU spread gradually until they meet, 

 I and the pool wiU be well furnished with foliage, but 

 I without any crowding. It is not necessary to put 

 'I soil at the bottom, although it may be done if desired. 

 1 It is sufficient to make a bundle of each plant by 

 ►f tying the roots up in some lumps of turfy soil in a 

 h piece of old sacking, or in moss or bracken. The 

 {; covering will soon rot away. It will be necessary to 

 !< weight the bundles with pieces of stone in order to 

 keep them down. If reeds are admired — and the 

 slender green growths have a pleasing effect when 

 rising above the water — ^roots may be tied up with the 

 Nymphaeas. The drawback to reeds is their brown- 

 ', ness throughout the winter. They have so tight a 

 L hold of the roots that it is impossible to pull them 

 I away without tearing up the whole clump, and the 

 I best plan is to cut them off as low as possible until the 

 I time comes for overhauling the whole contents of the 

 I pool, which should be done every second or third year. 

 It is a very shmy and singular looking mass which 

 will come up when the cleaning out is done. Roots
