large percentage of cows recover. Recently, how- 

 ever, it has been found that the disease may be 

 successfully controlled in nearly all cases by the 

 injection of any inert substance into the udder, as 

 for example, warm water, oxygen, or ordinary 

 air. The last method has been extensively used 

 and has given the best results of all treatments. 

 For the injection of air, it is simply necessary to 

 have a tube of the right size to fit the milk duct, 

 connected by means of a rubber tube with the air 

 pump. The udder is then tightly distended with 

 air after which the affected cow shows a rapid 

 recovery in ninety per cent, of cases or more. 



Garget is an inflammation of the udder also 

 known as mammitis and may occur in varying 

 degrees of severity. A mild case may yield to 

 treatment with hot poultices or manipulation with 

 the hands. Occasionally the disease is infectious 

 and then great care must be exercised to prevent 

 the spread of the disease. Some benefit has been 

 found from the use of an ointment containing three 

 ounces of belladonna in eight ounces of vaseline. 

 In cases of infectious garget the affected quarter 

 of the udder may become so changed in structure 

 as not to secrete milk thereafter. 



Bloating is due to the formation of gas in the 

 rumen or first stomach. Alfalfa, clover and corn 

 stalks appear to be most susceptible to fermen- 

 tation and are, therefore, most likely to cause 

 bloat. If the production of gas in the first stomach 

 is not too extensive it may be checked by adminis- 

 tering drenches of soda or by giving lard or some 

 inert oil. In violent cases where such a remedy 

 would act too slowly immediate relief is obtained 

 and the animal's life is saved by thrusting a knife 

 through the left side of the body at a point a few
