Prevention and Treatment of Parasites. 115 



its throat, perhaps one-third or one-half of it at 

 one time. Wait for a minute, then give some more 

 until all is taken. At least one or two pauses 

 should be made in order that a part of the dose 

 may not enter the lungs and prove fatal to the 

 sheep. The fingers of the left hand by which the 

 lamb's head is held should be left free, and the 

 under jaw should not be held tight up against the 

 upper jaw, which would, of course, prevent the 

 lamb from swallowing, and consequently the med- 

 icine would run down into its lungs and kill the 

 lamb instantly. An incorrect method of holding 

 lambs when drenching has killed many of them. 

 Some shepherds practice setting the sheep on its 

 rump with its head held high, but in the author's 

 experience this has not been found advisable. 

 When the sheep's head is held too high it cannot 

 swallow very well and the dose runs down its 

 windpipe into its lungs. This method of holding 

 the sheep should be followed not alone when sheep 

 are drenched to kill parasites but in all cases 

 where it is necessary for medicine to be given. Be 

 very particular to keep the fingers of your left 

 hand off from the under jaw while the medicine 

 is being given, and all will be well. Shortly after 

 dosing the lambs with gasoline or other remedies 

 they may again be turned out on grass each day.
