DISEASES OF HORSES AND CATTLE. 375 



wood is not of much importance as long as it is 

 grooved and strong enough not to bend. A caustic 

 is usually placed in the groove. I use bichloride of 

 mercury one part, and flour six parts, made into 

 a paste with water. It is best to prepare it when 

 you are going to use it. The clamp should be put 

 well down on the cord and tied tight at both ends. 

 Some have the idea that it gives the animal more 

 courage to leave the cords long, what they call 

 "Proud." This is a mistake, as when the clamp 

 is taken off the end of the cord may hang out and 

 become diseased. The clamps should be left on 

 for twenty-four hours, and when taken off the 

 cord should be pushed up into the cavity. When 

 rupture is present the outer skin only should be 

 cut and pushed back, the testicle drawn up, the 

 bowel pressed in, and a clamp put on, without any 

 caustic on it, and left on until it sloughs off. An- 

 other method is to push the bowel in and put only 

 one clamp over skin and all, and let it remain on 

 until it sloughs off. I think this is the best way. If 

 a clamp should come off and bleeding take place 

 it will be necessary to cast the colt, find the cord, 

 and put on the clamp again. If the bleeding is 

 not very great it is best to keep the animal quiet 

 for a while and it may stop of its own accord. I 

 have seen several cases in which it stopped with- 

 out interference. If the cord cannot be found and 

 the bleeding is very copious stop it by taking some 

 cotton batting and wetting it with tincture of 

 chloride of iron or carbolic acid one part, oil or 

 glycerine two parts, and pushing this into the
