on page 33 will give some idea of how these studies may be worked out 

 until by a process of reasoning and elimination the desired solution is 

 achieved. 



Upon a large place where the landscape architect will be employed 

 in the development of the plans a more accurate survey will be desirable, 

 if the property is irregular and if there is the problem of grades to be 

 considered, a topographical map will be necessary. (Fig. 8.) The 

 contour of the ground being shown by lines, each line represents a unit 

 of difference in grade; in some cases the difference in grade is one foot, 

 while in other cases it is two or more, varying according to the size and 

 irregularity of the project and with the accuracy desired. The topo- 

 graphical map should be made by a reputable engineer or landscape 

 architect. When completed as many blue prints can be secured by the 

 client as is desired.
