630 SCABIES— SCAB — MANGE. 



solution ample time to settle ; then only the clear liquid should be used, 

 while the sediment should be discarded. In some of the above tests on 

 samples of wool it was found that the dip with sediment had produced 

 very serious effects, even when no appreciable effects were noticed on 

 samples dipped in the corresponding clear liquid. 



Experience has amply demonstrated that a properly made and 

 properly used lime-and-sulphur dip is one of the cheapest and most 

 efficient scab eradicators known, but its use should be confined to flocks 

 in which scab is known to exist, and to shorn sheep, with the exception 

 of very severe cases of scab in unshorn sheep. It should only be used 

 when it can be properly boiled and settled. The use of lime-and-sulphur 

 dips in flocks not known to have scab, especially if the sheep are full 

 fleeced, cannot be recommended ; in such cases tobacco, or sulphur and 

 tobacco, is safer and equally good. 



All things considered, where it is a choice between sacrificing the 

 weight of sheep and to some extent the colour of the wool by using 

 tobacco and sulphur, and sacrificing the staple of the wool by using lime 

 and sulphur, the owner should not hesitate an instant in selecting 

 tobacco in preference to lime. The loss in weight by using tobacco and 

 sulphur is not much greater than the loss in using lime and sulphur, 

 while the loss in staple is of more importance than a slight discoloration. 



Preparation of tJw mixture. — Take 8 to 11 lbs. of unslaked lime, 

 place it in a mortar-box or a kettle or pail of some kind, and add 

 enough water to slake the lime and form a "lime paste" or "lime 

 putty." * 



Sift into this lime paste three times as many pounds of flowers of 

 sulphur as of lime, and stir the mixture well. 



Be sure to weigh both the lime and the sulphur. Do not trust to 

 measuring them in a bucket or to guessing at the weight. 



Place the sulphur-lime paste in a kettle or boiler with about twenty- 

 five to thirty gallons of boiling water, and boil the mixture for two hours 

 at least, stirring the liquid and sediment. The boiling should be con- 

 tinued until the sulphur disappears, or almost disappears, from the sur- 

 face ; the solution is then of a chocolate or liver colour. The longer the 

 solution boils the more the sulphur is dissolved and the less caustic the 

 ooze becomes. 



Pour the mixture and sediment into a tub or barrel placed near the 



* Many persons prefer to slake the lime to a powder, which is to be sifted and 

 mixed with sifted sulphur. One pint of water will slake 3 lbs. of lime if the 

 slaking is performed slowly and carefully. As a rule, however, it is necessary to use 

 more water. This method takes more time and requires more work than the one 

 given above, and does not give any better results. If the boiled solution is allowed 

 to settle the ooze will be equally safe
