from the sheep to flow from all parts of the draining yards into 

 the race and thence into the vat. 



Corrugated iron laid down in sheets on sleepers, with the 

 fluting running longitudinally towards the vat, makes a very 

 good and economical flooring for the gangway and draining 

 yards. With a piece of batten nailed across the end of the 

 sheet next to the vat, and at each joint, the sheep can walk out 

 steadily and without slipping ; and the mixture falling from 

 the sheep is carried back without waste to the vat. A movable 

 sluice-gate should be constructed at the junction of the drain- 

 ing yards with a race from the vat, and a spout or pipe should 

 be affixed to an opening from that to a point clear of the vat, 

 to run off any rain-water that might gather in the draining 

 yard, and prevent it from flowing into the dip. When in work 

 the sluice-gate would of course be removed, and the opening to 

 the spout or pipe closed. 



The effect of the tobacco is to destroy the small mites which 

 cause the disease. The breaking up of the scabs to permit the 

 dipping fluid to reach the insect is therefore of great use when 

 the sheep are badly diseased. But the practice of dipping the 

 sheep should be made use of regularly, once at least each year, 

 as a preventive of danger of this disease, as well as to free the 

 sheep from ticks. The dipping yards should, therefore, be a 

 part of every well appointed ranche, as much as a shearing floor 

 is, the expenses being small makes its neglect all the less exr 

 disable.
