almost a certainty that it is a case of navicular or 

 coffin joint lameness. The result is contraction of 

 the foot. 



Take off the shoes, so that the frog will rest on 

 the ground, then poultice the feet with bran, made 

 up with cold water if it is a recent case, but if it is 

 of some months' standing hot water is better than 

 cold; put the poultices into bags made a little 

 larger than the foot ; put about two inches deep of 

 the bran mash into the bag, then put the foot in 

 and fill in all around as high as the fetlock, and tie 

 the bag above the fetlock and around the ankle to 

 keep it well on the foot. Wet this several times a 

 day and change it once daily. Continue this for 

 two weeks, and see that it is properly done ; if not, 

 it will be of no service. Then blister the coronet 

 with cantharides 2 teaspoonfuls and lard 4 table- 

 spoonfuls. Repeat in three weeks, and give the 

 animal a long rest.

NODULAR DISEASE IN SHEEP. Nodules 

 resembling those of tuberculosis found in the in- 

 testines of sheep, are due to the presence of para- 

 sitic worms. Profuse diarrhoea and a pronounced 

 anemic condition prevail. A post mortem exami- 

 nation of the intestines discloses the presence of 

 numerous nodules in the intestinal walls. If the 

 worm is present, no treatment is possible, for the 

 reason that any medicine that would affect the 

 worm would also affect the tissues and lead to 

 their destruction. Prevention, therefore, is the 

 only means of overcoming the disease. Sheep must 

 be kept off infested pastures, and infested pastures 

 must be plowed and given over to cultivated crops. 

 IGive lambs only clean pastures to graze over. This 

 means crop rotation in connection with sheep hus*
