100 A MANUAL OF FORESTRY. 



d. Fencing. 



The nursery must be thoroughly protected against 

 cattle and game by fencing it substantially. The 

 nature of the fence depends on circumstances (see page 

 19); it may consist of a stone wall, wooden or wire 

 fence, living hedge, etc. ; stone walls are liable to inter-

 hedges take some years to grow. Of late years wire 

 fences, if necessary combined with rabbit netting, have 

 grown in public favour. 



e. Draining. 



This will, as a rule, not be necessary, as soil which 

 requires draining should not be chosen for a nursery. 

 Where no other site is available, the draining may be so 

 arranged that the water is collected in a well at the lowest 

 point of the nursery, to be used for watering during dry 

 weather. 



/. Watering. 



As a general rule watering will be required ; hence the 

 importance of choosing a site situated in the vicinity of a 

 spring, stream, or tank, from which the water can be 

 easily brought into the nursery. In the absence of such 

 a supply one or more wells must be sunk, and the water 

 lifted. 



The water can be distributed by hand, or by irrigation. 

 The former method is expensive and less effective, so that 

 it should only be employed where irrigation is im- 

 practicable. The latter can be done in two ways, by 

 percolation or by flooding, according as to whether the 

 water stands in channels between the beds, or is allowed
