Geometrical curves, part of a large design in- 

 volving straight lines as well, need no excuse. 



Over an irregular surface paths should be laid 

 with reference to the lie of the land, curving

round the high portions, and generally keeping 

 in the valleys. When necessary to carry over a 

 slope they should pass over at the lowest point 

 and take the gradient in wide sweeps. By work- 

 ing at right angles across the dip it is possible to

make paths of the easiest gradients, carving the 

 ground as in Diagram 32. The low side should 

 be planted when the slope is great, to increase the 

 appearance of breadth (Diagram 33.) Paths cut
