918 CYCLOPEDIA OF LIVE STOCK AND COMPLETE STOCK DOCTOR. 



Northwest under the observation and supervision of inspectors of this 

 Bureau ; Dr. A. D. Melvin, Assistant Chief of the Bureau, and Dr. Robert 

 H. Treacy, Inspecter, having submitted plans and specifications, which 

 will be found further on. 



The dip previously used contained an excess of lime, and frequently 

 proved quite irritating to the eyes and tender parts of the skin ; hence the 

 lime-and-sulphur dip now adopted and recommended for the treatment of 

 scabies of cattle is made with the following ingredients : 



Flowers of sulphur pounds. . 24 



Unslaked lime do ... . 12 



"Water gallons . . 100 



Place the unslaked lime in a mortar box or some suitable vessel and add 

 enough water to slake it and form a lime paste or lime putty. Sift into 

 this lime paste the flowers of sulphur and stir the mixture well. Be sure 

 to weigh both the lime and the sulphur, and do not trust to measure them 

 in a bucket or guess at the weight. Place the sulphur and lime paste in 

 a kettle or boiler with about 25 or 30 gallons of boiling water, and boil the 

 mixture for two hours at least, stirring the liquid and sediment. The 

 boiling should be continued until the sulphur disappears, or almost dis- 

 appears, from the surface. The solution is then of a chocolate or liver 

 color. The longer the solution boils the more the sulphur is dissolved, 

 and the less caustic the ooze becomes. Some writers advise boiling from 

 thirty to forty minutes, but this is not sufficient ; a good ooze can be ob- 

 tained only by boiling from two to three hours, adding water when neces- 

 sary. Pour the mixture and sediment into a large tub or barrel, placed 

 near the dipping vat and provided with a bunghole about 4 inches from 

 the bottom, and allow it ample time (from two to three hours or more if 

 necessary) to settle. 



The use of some kind of a settling tank provided with a bunghole is 

 an absolute necessity, unless the boiler is so arranged that it may be used 

 for both boiling and settling. An ordinary kerosene oil barrel will answer 

 very well as a small settling tank. To insert a spigot about 3 to 4 inches 

 from the bottom is an easy matter. Draining off the liquid through a 

 spigot has a great advantage over dipping it out because less commotion 

 occurs in the liquid, which therefore remains freer from sediment. When 

 fully settled, draw off the clear liquid into the dipping vat and add enough 

 warm water to make lOO gallons. But under no circumstances should 

 the sediment in the barrel be used for dipping purposes. A double pre- 

 caution against allowing the sediment to enter the vat is to strain the liquid 

 through ordinary bagging as it is drawn from the barrel or settling tank. 



The above directions are for the quantity of dip given in the preceding 

 formula. Any multiple of the constituents may be used, depending upon
