SHEEP DIPPING TANKS

from reaching the tank by way of the sump, a rain-water outlet from the 

 gutter is provided. 



A plate, P (Figs. 194 and 195), fits into a groove in this outlet, and 

 also into a similar groove in the spout opening from the gutter towards 

 the sump. When dipping is in progress this plate is placed in the former 

 groove, and when finished it is returned to the latter. 



The dripping pens are fenced with jackal-proof netting. It will be 

 noticed from Figs. 193 and 194 that three of the fencing posts pass 

 through the concrete of the gutter. These three should be selected,

thoroughly seasoned posts, stripped of bark, and should be bedded in 

 concrete. 



Drying Yard. — From the dripping pens the sheep are passed into the 

 drying yard, where they are held till dry enough to prevent their 

 poisoning the pasture by dripping. 



Receiving Yard. — This is for the purpose of holding the flock while 

 the members thereof are awaiting dipping. It has an area of approxi- 

 mately 800 square feet. 



The fence shown on the left of Fig. 193 is a rail fence of rough 

 eucalyptus posts and wattle rails, and extends past the entrance gate, 

 to form a wing against which the flock may be driven, thus rendering 

 it easier to get the sheep into the receiving yard. 



All fencing posts used in this and other yards should be thoroughly 

 dry, and should have the part which enters the ground either tarred 

 and sanded, or charred. The charring may be done over a " mest " 

 fire, and should be allowed to penetrate to a depth of about \ inch, 

 when the post should be removed from the fire and the charring 

 stopped by throwing water over it. The remaining fencing of this 

 yard, and of the drying yard and dripping pens, may consist of 

 jackal netting 4 feet high, with at least fifteen horizontal wires.
