In case of fresh scab Formula No. 4 will act as efficaciously as 

 the dips with a greater amount of lime, but in cases of very hard 

 scab a stronger dip, as the Fort Collins dip, should be preferred ; 

 or, in unusually severe cases, an ooze with more lime in proportion 

 to the amount of sulphur, such as the Victorian (No. 1) or the 

 South African (No. 2) dip might be used. 



Prejudice against Lime -and- Sulphur Dips. 



There is at present great prejudice (a certain amount of it justi- 

 fied, no doubt) against the use of lime and sulphur, emanating 

 chiefly from the agents of patent or proprietary dips and from the 

 wool manufacturers. 



In the first place, it is frequently asserted that lime and sulphur 

 does not cure scab. Experience in Australia and South Africa, as 

 well as in America, has shown beyond any doubt that a lime-and- 

 sulphur dip, when properly proportioned, properly prepared, and 

 properly used, is one of the best scab eradicators known. 



It is claimed by some that it produces '' blood poisoning." But 

 the cases of death following the use of lime-and-sulphur dips have 

 been infinitesimally few when compared with the number of sheep 

 dipped in these solutions, and when compared with the deaths which 

 have been known to follow the use of certain proprietary dips. The 

 details of such accidents, so far as they have been reported, have 

 not shown that death was due to any properly prepared and pro- 

 perly used lime-and-sulphur dip. It is highly probable that the cases 

 of so-called "blood poisoning" of shear-cut sheep are generally due to 

 an infection with bacteria in stale dip containing putrefying material. 



The greatest objection raised against the use of lime-and-sulphur 

 dip is that it injures the wool. This objection is raised by many 

 wool manufacturers, and echoed with ever-increasing emphasis *by 

 the manufacturers of prepared dips ; while, after years of extensive
