STOCKING WATEKS WITH FOOD 



tively deep water in ponds or lakes, lakewort 

 and stonewort grow on the bottom, and do not, 

 as a rule, attain any considerable height. White 

 and yellow water-lilies also grow in fairly deep 

 water; the water-lobelia is also an excellent 

 plant for ponds. 



In streams some of the best plants are water- 

 crowfoot, water-starwort, and the great water 

 moss. Anacharis should not be introduced into 

 any water, either pond or stream, unless it can be 

 kept down easily. It will otherwise become an 

 unmitigated nuisance. 



Marginal plants are a very important considera- 

 tion, and plenty of them should be grown. 

 Water-celery and water-cress are perhaps the 

 best food-producing marginal plants that can be 

 grown. Bullrushes and brooklime are also good, 

 but the bullrushes must be planted judiciously.
