After the plants are in their summer quarters little remains to be done; 

 the overflow having been lixed so that the water level will be about six inches 

 below full water mark. After the plants have made a good start and are 

 growing vigorously, the water should be raised to the full height, and any scum 

 that may collect on the surface should be cleared off by the use of the garden 

 hose, spraying towards the flow; attention must be given that the pond be kept 

 full to running over, as there will be more or less evaporation taking place, 

 conditional on the weather and quantity of surface clear; after the surface is 

 covered with foliage, evaporation will be less. As the season advances, tm- 

 sightly and dead leaves should be removed; conferva; may accumulate, but 

 the amount of care and attention necessary will be comparatively small.
