clean up from meal to meal, as this is likely to result in one or 

 more of them overeating. 



While water, salt, and succulent food of some kind are neces- 

 sary to the well being of sheep, care must be exercised in feeding 

 them, as otherwise they are likely to produce kidney and bladder 

 troubles. Drinking too much hard water, the result of eating 

 large quantities of salt, causes the deposit of limy substance in 

 the bladder, which becomes washed into the urethra, where 

 it lodges, causing stoppage of the urine, inflammation, followed 

 by distention of the bladder, which after a time results in death. 

 The long-continued feeding of too many mangels, rich in lime, 

 is likely to give similar results. 



OTHER DISEASES 



Caked udder. — This trouble often occurs among heavy milk- 

 ers. In most cases it is due to neglect at lambing time. The 

 udder becomes greatly distended, inflamed, and swollen. The 

 treatment is to relieve the congestion by drawing the milk, fre- 

 quently. Bathe the parts with hot water and apply camphor 

 ointment, as in caked udder among dairy cattle. Some 

 prefer an ointment made of lard and turpentine, equal parts. 

 The ointment should be well rubbed in and applied three 

 times daily. 



Garget often proves serious in certain localities. It is said 

 to be due to mechanical injuries, such as a blow, a scratch, or the 

 udder being horned ; to the udder becoming distended with milk; 

 and to germs entering the udder. The udder becomes hard, 

 distended, and the milk is often watery and may contain 

 blood. The treatment usually recommended is the hot water 

 bathing and the camphor-belladonna ointment treatment, as 

 suggested for cows (page 340). 



Among sheep, however, garget seems to be due to other causes 

 as well, and when such is the case, the above treatment often fails 

 of relief. A typical case is somewhat as follows : A strong ewe
