 POOL

tural features. A warm red brick with light joints, laid upon edge, 

 makes an attractive coping. A coping of cut stone or marble will be 

 found suitable in many cases. Although it is humanly possible to make 

 an attractive concrete coping, the author has never seen one which even 

 approximates in beauty and finish a coping of cut stone. 



A strip of at least one foot should be left about the pool for plant- 

 ing for sod. When this planting is omitted about a pool the effect 

 will be harsh and, not nearly so pleasing as when there is a planting of 

 violets, iris, or other low plant?., or sod, to break the harsh lines made 

 by the coping meeting the walks. This strip, however, can often be 

 omitted when the pool is a small one constructed upon a paved terrace 

 and when the coping is really a part of the paved area about it. 



A pool can be as shallow as eighteen inches and still have six 

 inches in which to plant water plants, with one foot of water over 

 them. There is no object in having a pool too deep, for children 

 enjoy playing about a pool, which, if too deep, becomes dangerous. 



The floor of a pool should be at least four inches thick, of rein- 

 forced concrete, with a one-inch coat of waterproof Portland cement 

 applied as a finish. The floor should be laid upon five inches of cin- 

 ders or gravel to prevent heaving.
