238 Prescriptions for Sheep-Dips. [June, 



of a right of sporting over land might properly be included in estimating 

 the rateable value of a plantation or wood as land in its natural and 

 unimproved state. 



The Board request that the matter may have the consideration of 

 the Assessment Committee with a view to determining whether there 

 are any cases in their district in which the assessment of woodlands 

 calls for revision. 



I am, &c, 



H. C. Monro, Secretary. 



The following prescriptions for Sheep-Dips have been approved by 

 the Board of Agriculture and Fisheries for Sheep Scab, and can be used 

 by sheep owners who prefer to make up their 



Prescriptions for own dips. 



Sheep-Dips. ( J ) Lime and Sulphur. — Mix 25 lb. of 



flowers of sulphur with 12^ lb. of good quick- 

 lime. Pound or rub the mixture with water until a smooth cream 

 without lumps is obtained. Transfer this to a boiler capable of boiling 

 20 gallons ; add to the mixture sufficient water to make up 20 gallons ; 

 boil and stir for half an hour. The liquid should then be of a dark 

 red colour; if yellowish, continue the boiling until the dark red colour 

 is obtained, keeping the amount of liquid up to 20 gallons by adding 

 water if necessary. u 



Half the above quantities may be used to make 10 gallons, if more 

 convenient. 



After the liquid has cooled, pour it off from any small quantity of 

 insoluble sediment. 



To 20 gallons of the mixture add 80 gallons of water to make a bath. 



The mixture will keep good for twenty-four hours if kept in a 

 covered vessel, and for a* month or even more if kept in jars or drums 

 securely corked. 



Period of immersion for sheep in this dip, not less than half a minute. 



(2) Carbolic Acid and Soft Soap. — Dissolve 5 lb. of good soft soap, 

 with gentle warming, in 3 quarts of liquid carbolic acid (containing not 

 less than 97 per cent, of real tar acid). Mix the liquid with enough 

 water to make 100 gallons for the bath. 



This mixture after being prepared will keep good for three months 

 if kept in securely stoppered jars or drums in a cool place. 



Period of immersion for sheep in this dip, not less than half a minute. 



(3) Tobacco and Sulphur. — Steep 35 lb. of finely ground tobacco 

 (known as offal tobacco) in 21 gallons of water for four days. Strain 

 off the liquid and remove the last portions of the extract by pressing 

 the remaining tobacco. Mix the whole extract and add to it 10 lb. 

 of flowers of sulphur. Stir the mixture well, to secure its being evenly 

 mixed, and add sufficient water to make up 100 gallons for the bath. 



This mixture will not keep. 



Period of immersion for sheep in this dip, not less than half a minute. 



In every case the dip-bath should be of sufficient volume to allow 

 of each sheep being completely immersed in the bath. 



Where a number of sheep are to be dipped, the bath must be cleaned 

 out from time to time, otherwise the efficacy of the dipping may be 

 impaired.
