4. Nevada lime-and-sulphur dip: 



Flowers of sulphur pounds 16 2-3 



Lime do . . 33 



Water gallons 100 



5. Fort Collins lime-and-sulphur dip : 



Flowers of sulphur pounds 33 



Unslaked lime do . . 11 



Water gallons 100 



6. A mixture used extensively and with general satisfaction, contains 

 the same proportions of lime and sulphur (namely 1 to 3) as the 

 Fort Collins dip, but the quantities are reduced to: 



Flowers of sulphur pounds 24 



Unslaked lime do. . 8 



Water gallons 100 



In case of fresh scab, formula No. 6 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), the South 

 African (No. 3), or the Nevada (No. 4) dip might be used. 



Dangerous Formulas. Among the dangerous formulas for 

 lime-and-sulphur dips are the following: 

 a. California lime-and-sulphur dip : 



Flowers of sulphur pounds 100 



Lime . . . do . . 25 



Water gallons 100 



A very dangerous misprinted formula is found in several books 

 and journals, probably due to a typographical error, which specifies 

 a much larger proportion of lime than any of tnose mentioned 

 above. Thirty-three pounds of lime to 100 gallons of water is the 

 largest proportion admissible under any circumstances, and 16 2-3 

 pounds is as much as should be used without expert advice and su- 

 pervision. 



All things considered, where it is a choice between sacrificing 

 the weight of sheep, and to some extent the color of the wool, by 

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

 using lime and sulphur, the farmer 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 im- 

 portance than a slight discoloration. 



Preparation of Lime-and-Sulphur Mixture. Almost as many 

 different methods of preparing the liquid exists as there are different 

 formulas, some of the methods laying great stress upon sifting both 

 the lime and the sulphur, others laying great stress upon allowing 

 the liquid to settle, others leaving out of consideration both of these 

 points. The method which has been found to be the easiest and 

 most satisfactory is as follows :
