 lawn should be some distance away from the house to make drainage 

 possible. (Fig. 2B). If the house is above the level of the street the 

 grounds graded in an ogee curve from the street to t'le house 

 will be found most pleasing to the eye while a lawn graded to a con- 

 vex surface will not prove nearly so satisfactory. (Figs. 2C and 2D). 

 A considerable difference of levels between the house and street 

 will often require the use of retaining walls and terraces to make the 

 necessary transition. The maximum slope that can be given in an 

 area is largely dependent upon the maximum slope that can be given 

 the approach walk. 



Terraces near the house are really a part of the house and should 

 be so considered and designed. The width of the terrace should be 

 such that it is in scale with the building. The house terrace should be 

 architecturally treated, being regular in line, with the upper line par-

 be of a nature to conform with approach steps; a minimum slope of
