ARCHITECTURAL FEATURES OF THE GARDEN 179 



PLANTING NEAR GARDEN POOLS 



The planting near garden pools should include some bright 

 colored flowering plants in positions where they will reflect all the 

 glory of their color on the surface of the water, for the pool is a 

 delightful outdoor mirror, reflecting all its en-\-ironment with a soft- 

 ness that is most charming. 



PLANTS IN THE POOL 



The garden pool is not complete, nor affording one of its greatest 

 pleasures, if it does not support some Water Lilies (Fig. 140). 



In tightly built pools it is' necessary to plant the Lilies in tubs. 

 A very economical and satisfactory tub may be provided by cutting 

 in two an old vinegar or liquor barrel. 



The soil for the proper support of the Lilies should consist of 

 a good loam well enriched with decomposed cow manure, equal to 

 one-fifth of the entire bulk. On top of this place two inches of bar 

 sand. The tubs should be set to a depth that will allow about six 

 inches of water over the soil. 



THE PLANTS 



For the average garden pool a selection from the many varieties 

 obtainable of hardy and tender Nymph £eas will be found most 

 satisfactory. 



These may be planted just as they start into growth, usually 

 about May 1 in the vicinity of Philadelphia; at that time all danger 

 of frost is over and even the tender kinds may be safely set out. 



Only sufficient fresh water need be supplied to the pool to pro^'ide 

 for that lost through evaporation. 



The Nelumbiums are very handsome, of easy culture and well 

 suited to large pools. Other good aquatic plants are the Water 

 Hyacinth, Water Snowflake, Papyrus or Umbrella Plant. 



The hardy varieties may be left in the pool all Winter; but they 

 require a protection of lea\'es, with evergreen boughs or boards over 

 them to keep the leaves in place. 



FISH 



It is well to stock garden pools with goldfish to destroy mos- 

 quito larvae, and to add the requisite touch of life and color. 



SWIMMING POOLS 



The loss of so many of the old-time swimming holes has developed 

 a demand for the artificial swimming pool.
