 jumpers it is frequently necessary to construct a slide of steel or wood. A 

 railing around the starting platform at the top and along both sides of the 

 slide should be provided. Unless the starting platform is reached by climb- 

 ing a natural slope, a walk may be provided along one side of the slide, 

 furnished with cleats to prevent slipping. Beginners should not be permitted 

 to use these jumps. 



Sled and toboggan slides. Where natural facilities for coasting are 

 limited or lacking, artificial slides should be constructed. A slide of only 

 a few feet erected in a park or playground will provide healthful exercise and 

 fun for hundreds of children. Few expenditures are more easily justified. 

 In more than one city the roof of the shelter house is used as the platform 

 or starting place for a slide. This may be used only in winter or throughout 

 the entire year. Frequently chutes are constructed, using a grand stand or
