48 PRACTICAL LANDSCAPE GARDENING 



running at right angles to the side of the walk. The roughened 

 strips should be three inches wide and the smooth strips two inches 

 wide. 



The use of cement has become so universal that it is really 

 monotonous and, when possible, a material should be used that is 

 more in tune with the natural surroundings. 



MACADAM WALKS 



Well kept macadam walks (Fig. 43) require more care than 

 cement walks, but are a little more pleasing on a lawn. Use three 

 inches of two and one-half inch stone, two inches of one and one- 

 half inch stone, and one inch of breaker dust. Wet thoroughly and 

 roll to a hard and even surface. Quarry spawls may be used for the 

 two and one-half inch stone if securable near at hand; this would 

 materially reduce the cost. Such walks cost about seventy cents per 

 square yard under favorable conditions. A macadam walk is more 

 satisfactory from a landscape point of view than cement. On properties 

 where steep grades are encountered provision must be made for 

 proper drainage, else the cost of maintenance will be prohibitive. 

 Gutters and catch basins should be installed at intervals. Macadam 

 walks should have a crown of one-half inch to the foot. 



RED GRAVEL WALKS 



A surface of one to two inches of red gravel on the same base as 

 recommended for the macadam path makes a walk that is really the 

 best for paths within the property borders. Gravel walks are sub- 

 ject to surface washing and should be provided with gutters and 

 catch basins. 



FLAGSTONE WALKS 



Flagstone walks, made with flags of North River blue stone or 

 Indiana limestone, are the most serviceable of all walks. 



The flags should be two to three inches thick and should be laid 

 on a sub-base of cinders not less than si.x inches deep. Wet the 

 cinders and tamp them to a hard, even surface; over this place one 

 inch of bar sand compacted as a cushion for the flags. After the slabs 

 are leveled and firmed the joints should be pointed with a flat cement 

 mortar joint. 



It is customary to lay flags cut in single blocks of various lengths 

 to the full width of the walk.
