WATER LILIES.

Sir: — Water lilies may be growu in this vicinity without any 

 particular trouble, as follows : 



Use a pond — not more than two feet deep — or build a cement 

 basin of any shape ; an irregular outline is the most effective. 



No stone or brickwork is necessary. Use Roseudale cement 

 mixed, one to four parts, with sand for a foundation. Slope the 

 sides of the pond a good deal, as lilies require area more than 

 depth. Eighteen inches is deep enough. 



Over this Rosendale cement spread Portland cement mixed with 

 sand, one to four parts, and finally wash the whole with pure 

 Portland cement, using a broom to spread it. Fill with water and 

 test before putting in loam and manure. 



When the pond is tight take cow and horse manure and fill in 

 about six inches deep ; on this put two or three inches of loam 

 and cover the whole with sand two inches deep. This last keeps 

 the water clear and prevents the manure from floating on the 

 surface of the water. 



The best lilies in a pond where no artificial heat is used, are 



Nymplicea alba cancUdissima. Nymphcea sulplmrea. 



" Marliacea cliromatella. " Zanzibarensis azurea 



" odorata rosea (ipmkhly). " " rosea. 



The following will also do well unless the season is very cold : 



Nymphoia dentata, ) 



Devoniensis, I night bloomers, 



rubra, J ^ ^- ''• ^« ^^ ^- ''■ 



To prevent snails, put goldfish in the pond, after the first week 

 or two, or when the freshness of the cement is passed.
