ground as instructed. By shifting them 

 backward and forward, and from side to 

 side, most pleasing eflFects can easily be pro- 

 duced. 



In very few cases are regular curves really 

 necessary. Occasionally, however, as in 

 making turns for carriage drives, it is de- 

 sirable that true results be obtained. In 

 tracing contra curves it is very desirable that 

 they be very nearly true, and especially if 

 these are parallel as might be the case in 

 extending a turf walk from the lawn proper 

 to the other parts of the garden. In these 

 cases one curve should be traced first by the 

 eye and, the stakes having been finally driven, 

 the opposite curve is then laid by a repro- 

 duction of the first. 



We will suppose a straight line. The gar- 

 den line may be used to mark this. The two 

 ends of the line should mark the extreme 

 ends of the contra curve which will cross 

 the line exactly at its centre. Measuring 

 from the beginning of one curve to the point 

 of intersection between the curve and garden 

 line, find the centre, and from that measure 

 the distance to the outline of the curve. Lay 

 it off similarly on the opposite side of the line
