CEMETERIES 293 



necessary to select a clay soil because there was no 

 other, or to make ground by excavating lakes, using 

 the material excavated to raise the surrounding land, 

 or to inter above ground in structures erected for 

 the purpose, as at New Orleans. 



SUBDIVISIONS, WALKS, AND DRIVES (Fig. 55) 



When a site is chosen, it is usually subdivided into 

 sections and lots, which must be made accessible by 

 the construction of drives and walks. A road should 

 pass within about 150 feet of every lot. The width 

 of the roadways should vary according to the size 

 of the cemetery and the probable amount of driving. 

 If the area is very small, a drive may be unnecessary. 

 As cemeteries increase in size, a grass walk eight feet 

 in width may answer every purpose, using this when 

 needed as a drive ; then a driveway sixteen feet in 

 width may be required in a somewhat larger area so 

 that vehicles can pass each other ; and, finally, a 

 cemetery designed to accommodate large populations 

 should have good roadways, usually twenty-four feet 

 in width. Formerly these roadways would have 

 been constructed of ordinary macadam or gravel, 

 but \vith the increased use of automobiles, the ma-
