 or reason. At the same time straight lines 

 should generally be avoided. Therefore 

 masses of shrubbery, a flower bed, an old tree 

 retained from the original clearing, or a rock 

 abutting from the ground, should be worked 

 into the scheme. These "obstacles" may 

 not be merely natural features. They can

 ber and variety of the curves must be in pro- 

 portion to the surface and contour of the 

 ground. The more hilly or undulating it is 

 the more numerous may be the curves. The 

 entrance from the public road is made at 

 right angles so as to give the greatest ease 

 of approach from all directions. But if 

 there is room the curve should begin imme-
