The fencing posts for the dripping race should be of well-seasoned 

 hardwood and are best bedded in concrete. The best job would be 



made by having the posts of sawn hard- 

 wood (say 5" by 5") bedded in concrete, 

 with 4£" by 3" deal rails checked and 

 bolted to them, and tarred; but if a first- 

 class job is too expensive then rough posts 

 and rails may be used, say gum-posts and 

 wattle-rails, the ends of the posts which 

 enter the ground being charred or tarred. 

 The posts for the splash-boards may consist 

 of 4" by 4" hardwood bedded in concrete 

 as shown in Fig. 189. The remarks Jn 

 regard to cheaper posts for the race apply 

 equally well here. 



Splash-boards or Roof-flaps. — These would 

 be too unwieldy if made in one piece extend- 

 ing over the whole length of the dip. They 

 are therefore made in sections, each side 

 consisting of four sections, constructed of 

 3" by 3" deals covered with plain or flat 

 galvanised iron of No. 24 gauge. Three of 

 these sections will each be approximately 

 12 feet in length, while the remaining one 

 will be about 6 feet 6 inches long. They 

 are carried by hook and band hinges from 

 the 4" by 4" posts. 



On these posts, opposite which the junc- 

 tion between adjacent sections come, a double hinge will be required. 

 This may consist of a double or T-shaped hook, carrying two bands, 

 one embracing each end of the head of the T, one band being for one 

 sectional flap, and the other for the adjoining one. The leg of the T 

 passes through the 4" by 4" hardwood post, and is secured by a nut 

 screwed on its end. Fig. 189 gives details of the roof-flaps, etc.
