PRACTICAL BOOK OF GARDEN ARCHITECTURE 



in the use of enamelled brick and similar material for 

 inside facing, the straight retaining walls will never 

 be quite so difficult to construct, to insure water- 

 tightness, as the walls of the curving surface. Five- 

 ply water-proofing paper is sometimes recommended 

 for use in connection with hot asphalt and concrete 

 to prevent the gentle leakage that sometimes makes 

 the swimming pool a care. Ordinary brick laid in 

 mortar and grouted is also used for the small pools. 



Tiles naturally have been the favorite facing for 

 the inside of the pools of the more expensive type, 

 but during recent years Carrara glass because it is 

 homogeneous has become still more popular for 

 facing the inside of the retaining walls and for the 

 flooring. 



Tile flooring, marbje basins, and Carrara glass 

 do not represent the ideal accessories for the average 

 swimming pool, however. Neither will the little nat- 

 ural brook supply, with its inexpensive dam, be 

 within reach of the average home. Concrete is the 

 happy medium that will meet the demand of the mul- 

 titude. Eeturning to the "Martyn theory" we are 

 convinced that a moderate-priced swimming pool 

 or at least a pool in keeping with its surroundings 

 should be considered as essential to the country home 

 as the barn or the ice-house, for it answers a funda- 

 mental need. Pools need not be one-priced any more
