or ill other i)arts of the udder; they may be, in some cases, 

 tuberculous modules. 



No doubt that filthy hands, dirty finger nails, open 

 the way to infection. Pus germs are very often found 

 on dirty finger nails and on the dirty skin of the udder; 

 moreover, long, sharp and rough finger nails are fine in- 

 struments for inoculation. 



Treatment consists in cleanliness and disinfection. 

 With the finger nails smooth and closely cut, and the 

 udder and hands thoroughly washed, chances for infec- 

 tion are very limited. 



After infection, wash the udder with water that has 

 been boiled and cooled ; apply a 2 per cent, creolin, lysol 

 or corbolic acid solution; or corrosive sublimate 1 part 

 and water 1,000 parts. Be sure to wash and disinfect 

 the udder well immediately after a furuncle erupts. Re- 

 member cleanliness of hands, finger nails and udder will 

 prevent it. 



OBSTEUCTIONS TO THE FLOW 01-^ MILK FROM 



THE TEAT. 



Chronic inflammation or irritation of the lining mem- 

 brane of milk duct or canal in the teat (through which 

 passes the milk from the milk reservoir or sinus in the 

 bag to the bucket or air at time of milking) may lead to 

 a graudual thickening of the lining membrane and conse- 

 quent narrowing of the duct. The milk will then flow 

 in a verv small stream and the calf or milker mav be un- 

 able to remove all of the milk, and thus "dry up" that 

 quarter or produce clotting of the milk or inflammation 

 of the bag ("garget" or "caked bag.") Chronic 

 inflammation may be a result of the growth of 

 germs in the small amount of milk left in the milk sinus 

 or duct, or the growth of germs in the lining membrane
