 vat must be provided. Some of the 

 dipping- vats now in use will allow 

 running through 10,000 to 15,000 sheep 

 a day. The tobacco and sulphur dip 

 is prepared from 1 pound of tobacco 

 leaves and 1 pound of sulphur for 

 each 6 gallons of water. The materials 



has not existed long. In old cases, how- 

 ever, with a large development of scab 

 and crusts over the affected parts, the 

 Fort Collins formula, calling for 11 

 pounds of lime and 33 pounds of sul- 

 phur jter 100 gallons of water, is recom-

Lime and sulphur dips have been pre- 

 pared according to various formulas con-

 last named formula is recommended as

should then be allowed to settle and the 

 clear liquid drawn off, adding enough

 the formulas just given. The federal 

 authorities recommend that the sedi-

 dipping vat, but in many instances
