milk tube will readily pass through it into the duct. 

 A little pressure may at first be necessary to enter 

 the point of the tube in the duct. 



A small strip of gauze saturated with glj^cerin is 

 then forced a short distance into the duct and allowed 

 to remain, with an inch or so protruding. This strip 

 of gauze is removed after twenty-four hours and the 

 heifer milked regularly. 



The restraint for this operation is always to be in 

 the recumbent position. If the operation is deftly per- 

 formed it is practically bloodless. 



In heifers this operation should be performed just 

 before or immediately after calving. 



We would call the veterinarian's attention again, 

 before closing the discussion, to what has been said, 

 about high strictures of the teat. Our experience is 

 that the veterinarian can serve his client best in most 

 of those cases by advising that the condition be left 

 alone, letting that particular quarter go dry.
