 especially in a park. In the 

 wading pool recently con- 

 structed in one of the West- 

 chester County parks the 

 bottom of the pool and the 

 surrounding walk were 

 sprinkled with small 

 rounded pebbles soon after 

 the concrete was poured. It 

 is believed that the pebbles 

 will prevent the children 

 from slipping on the wet 

 concrete. It is desirable to 

 have a concrete walk around 

 the pool to lessen the 



amount of dirt carried into it. If the walk is provided with drains, as in the 

 pool on page 353, the muddy surface which surrounds so many wading pools 



can be avoided. One or more 

 sand courts are frequently 

 constructed close to the wad- 

 ing pool. Frequently wading 

 pools are constructed adjacent 

 to a swimming pool as a part 

 of a swimming center plan. 



W ading- swimming pools. 

 In a number of cities, espe- 

 cially where outdoor swim- 

 ming facilities are lacking or 

 limited, wading pools have 

 been constructed which have a 

 section of sufficient depth to 

 permit swimming. The depth of these pools generally slopes from about 

 six to thirty-six or forty-two inches. Many park and recreation officials are
