The worm we have to deal with in the hog the most is the one that 

 is found in the mucous membranes. It has an entire set of suckers and 

 they go right into the skin of the abdomen and take out a lot of blood. 

 The solution is just strong enough so that when it goes into the body on 

 an empty stomach they release themselves and pass out. The powder 

 has to be given continuously so that by keeping the bowels free they 

 will pass out and the eggs don't mature. 



The next question is that of having hogs free from lice. Most breeders 

 have got wise to that and yet it is surprising how many men do not take 

 care of that one point and keep their hogs clear of lice and nits. These 

 lice are blood suckers and adhere largely where the skin is thinnest, 

 around the ears and on the abdomen, and do a great deal of mischief. 

 You can dip or you can spray. Dipping is pretty hard work, especially 

 if you have not your dipping arrangements made so that it is practical. 

 If you have a dipping apparatus, get it so that it is winding so that the 

 hogs cannot look ahead because you know hogs are pretty stubborn. It 

 is tiresome work to keep poking them along and they won't go. You 

 can make a dry battery which costs but little. Buy a cord and attach 

 it to your battery. Have a little end sticking out and all you have to do 

 is to poke Mr. Hog and he will give a jump. It will keep your temper 

 much better and you will get good results. It is the easiest thing in the 

 world to get a good hog out of order. 



You may ask me what is the best dip. At the present time I am using 

 crude oil, about an inch to an inch and a half on the water. Then I have 

 a number of rubbing posts on which I used crude oil. I like it because it 

 has a more lasting power than any other dip and it is the oily effect that 

 you want. That gets the nits. The first dipping will kill the lice that 

 are on the hog but it is the second crop of nits on the hair which will 

 hatch out in ten days that you want to be careful about. This oily stuff 

 will prevent these little nits from cropping out. 



While you are going to all this trouble of dipping there is one thing 

 that you want to bear in mind and that is if you have any rubbish lying 

 around your hog house, that is just what you want to burn up. They are 

 full of lice. You don't want to take a day off dipping hogs, probably in- 

 jure a good hog and feel bad about it for two weeks afterwards every time 

 you think of it, and then not remove the cause. Know the cause and 

 then remove it. 



I believe in feeding the hogs. We have found in this serum work that 

 by giving our hogs special rations we can secure a great deal more blood 

 even in the winter time and we know that some other stations have gone 

 out of business in the winter time. The different stations have shown 

 that by feeding balanced rations that they can increase the breaking 

 qualities of the bone. That is important you know. You will agree 

 that if you can increase the breaking quality from 800, which is the aver- 

 age, by just adding some little food to it, to a breaking point of 2,300 to 

 2,600 it is quite a difference. You will grant that if you can do that 

 that the animal ought to have more resisting power. From what I have 

 worked out I do believe that they would have more natural immunity and 

 would be stronger to resist disease.
