5. Rumenotomy. 
This operation is fully described in Chapter III., Sec- 
tion 10. 
6. Castration of Bulls. 
Secure him, either by standing him in a firm stall or 
throwing him down. This can be easily done by taking a 
rope about thirty feet long, make a loop in the centre large 
enough to slip over his head and neck and then tie a knot in 
it. After the rope is put over his head and fitted on the neck, 
pass it back between the front legs and bring the ends of it 
back one on each side and around the outside of the hind 
legs, and back around the inside just above the hock, then 
bring them forw^ard on the outside of the front legs through 
the loops. X Have a man on each side to pull on the ropes, 
which soon throws him down, then tie him up solid. This 
is the best method known for throwing cattle. 
As soon as you have secured him, take a sharp knife and 
make a cut along the side of the bag large enough to let the 
testicle out. Be sure the cut extends to the bottom of the 
\Mi.g so that it will form a pocket. As soon as you have let 
the testicle out, draw it well up and you will notice a white 
covering attached to the back part. Cut this ofif close to the 
testicle with your knife, then you can pull up the testicle and 
cord free. Pull the testicle and cord well up, and if the bull 
is over a year old, tie the cord with a strong, fine piece of 
string about four inches above the testicle, leaving the ends 
of the string six or eight inches long so that they hang out 
of the bag and will not heal up in it. Leave this string on 
until it drops ofif itself. Cut the testicles off below the string, 
fill the holes full of salty butter and let him go. 
The reason the string is tied on the cord when the animal 
is one year old and upwards is because there is danger of 
him bleeding to death. The operation of castrating a bull 
standing up is done by securing him in a solid, narrow stall 
and operating in the same manner as you would if he were 
lying down. 
7. Castration of Calves. 
Tie him or have some person hold him ; make the cuts 
in the bag the same as for castrating bulls. When the testicle 
is out, separate the covering attached to the back part of the 
testicle with your knife, draw the cord and testicle well up.
