 in gutters. Curb used in park work is most generally of 

 the curved variety and is very handsome when carefully laid,

 material to use. Curved curb can be made of concrete 

 with gutter of the same material. There is no good reason 

 why curved concrete curb should not present an excellent 

 appearance. This means that the engineer in charge of 

 the work shall be a man of good judgment in laying out

 may be necessary to secure the best results.

 ried underground in lead conduits. The lights may be 

 of the enclosed arc or the incandescent type the former 

 are usually preferred. Various kinds of ornamental iron 

 posts are used, the wires being carried up inside the post. 



Either direct or alternating current may be employed, 

 whichever is available. If the park is at some distance 

 from the supply, the alternating current will be found to 

 be cheaper. 



It is usual to provide distribution stations where the
