RURAL VETERINARY SECRETS 129 



whole of the liquid cannot be dra-vvn out by a single puncture. The 

 blister, in other words, is chambered and each chamber must be 

 opened in order to evacuate the whole of the contents. If the pock 

 forms on the surface where there is thick hair, it does not rise as a 

 blister, but oozes out a straw-colored fluid which concretes on the 

 liair in an amber-colored mass. In one or two days after the pock 

 is full it becomes yellow from contained pus and then dries into a 

 brownish, yellow scab (See Illustration), which finally falls, leaving 

 one or more distinct pits in the skin. Upon the teats, however, this 

 regular course is rarely seen ; the vesicles are burst by the hands 

 of the milker as soon as liquid is formed and as they continue to 

 suffer at each milking, they form raw, angry sores, scabbing more 

 or less at intervals, but slow to undergo healing. 



TREATMENT 



The only treatment is to heal the sores and to relieve the cow 

 of the painful torture of milking. To do this effectively wash the 

 udder and teats clean with warm water and castile soap after each milk- 

 ing. See that no soap-suds remain on udder or teats, then dry 

 thoroughly with a clean, dry towel. When the parts are thus 

 cleansed and dried, rub well with Glycerole (National) all affected 

 parts. This will tend to relieve the pain at once, soften the skin. 

 and hasten repair. It will surprise you how much more gentle the 

 cow will appear at the next milking, even after only one applica- 

 tion. Repeat the above until the pox disappear and always milk 

 the affected cows last so that you do not carry the germs to the 

 healthy ones of the herd, care being taken to have the hands of the 

 milker thoroughly clean.
