the operation is altogether too tedious. If a large 

 number of lambs are affected at the same time it 

 is almost impossible to give each one a drench of 

 any medicine several times. In the sheep business, 

 as in some other lines of animal industry, it is 

 necessary from a financial standpoint to be able to 

 apply remedies on a large scale in case of an out- 

 break of infectious disease. This is possible 

 with scab since dipping vats may be constructed 

 of such size that from three thousand to fifteen 

 thousand sheep may be run through in a day. The 

 remedies commonly used in treating stomach worms 

 are turpentine at the rate of one part in sixteen 

 parts 01 milk and given in doses of one to three 

 tablespoonfuls, or one tablespoonful of gasolene 

 in four ounces of sweet milk, or coal tar creosote 

 in doses of two to four ounces of a one-per-cent. so- 

 lution in water. The same treatment may be given 

 to goats or calves.

 consists in a frequent rotation of pastures so as 

 to prevent any pasture from becoming too thorough- 

 ly infected. In this way the lambs may be kept 

 from becoming infectea by eating grass soiled 

 with the droppings of other infested sheep. 



Lung Worms. In the lungs of sheep another 

 parasitic threadlike worm occurs which causes 

 coughing and sneezing and a discharge of mucus 

 from the nose. The skin becomes exceedingly 

 papery and gives rise to the name paper skin for 

 the disease. The treatment for this trouble as 

 usually recommended consists in driving the lambs 

 into a small closed space in which they are forced 

 to inhale irritating fumes. This causes violent 

 coughing which assists in expelling the worms.
