prefer the flood lights placed where they will cover the surface. Five 

 hundred-watt lamps are used for this, as many as are needed for the size 

 of the rink. Good lighting effects have been secured with a cable strung 

 at intervals of fifty feet across the rink, with a string of incandescent lights 

 fastened to it. 



Construction of Ice Skating Rink. 



The following statement by George H. Browne of Cambridge, Massa- 

 chusetts, published in Landscape Architecture, January 1915, describes a 

 method of building up an ice surface: "To build up ice on the ground it 

 must be sprayed up from the bottom. It cannot be gotten by flooding 

 unless the pool is water-tight and at least two zero nights are in prospect. 

 No matter how shallow the pool, provision must be made for draining off 

 surface water that will inevitably run in during a thaw. This may be done 

 by inserting a board in the clay bank or wall at the most appropriate place 

 for drainage, through which a hole is bored to drain off the water. The 

 process of spraying a smooth ice surface is analogous to electroplating, that 

 is, it has to be done in the thinnest layers possible. Success may best be 

 obtained from the intelligent manipulation of simple devices rather than 

 from the use of mechanical sprinklers. A simple method is for one man
