farmers would treat their hogs that are affected with lung worms in that 

 way and quarantine them we would soon get rid of it. Hogs infested 

 with lung worms will stand and cough. They don't do very well hut you 

 won't lose any of them. They don't have the tucked up condition of the 

 flank except in the latter stages. They will put on some flesh hut they 

 will not have the real bloom that you desire and you will find the lungs 

 entirely infested with little thread worms. Two or three years ago we 

 did not really believe the intestinal parasite had much to do with the 

 animal or really injured the animal. We are beginning to take more notice 

 since Dr. Styles down in the south has said so much about the hook 

 worm. You will find people there infested by only a few parasites but 

 they will develop a symptom that you can detect them out of many 

 thousands. We have in the west a disease in the intestines among 

 horses. The average veterinarian who has never seen this parasite would 

 probably pass it over and yet you could pick out a little handful that 

 would produce a distressing effect on the horse. So we are just begin- 

 ning to take notice of the intestinal parasite." 



Speaking further regarding the lung worm D. L. Howard said: 

 "I can tell you something that will get rid of this lung worm 

 that is safer than turpentine and that is kerosene oil. As I under- 

 stand it the germ of the lung worm finds its lodging in the bron- 

 chial tube. It hangs onto the walls and creates a tickling sensa- 

 tion which causes the hog to cough. Sometimes the hogs will die 

 but if they don't, they are of a weak constitution. When you are 

 rid of intestinal worms and your hogs still cough, they have lung 

 worms and a little kerosene will dislodge all the worms in the 

 throat. It will not get into the lungs and if there are many in the 

 lungs you will lose the hog. I know of a party in southeastern 

 Iowa who had been raising sheep for thirty years on his farm 

 and that ground got so infested with lung worms that it was im- 

 possible for him to develop his sheep so he disposed of the sheep 

 and got forty head of two-year-old steers and in about three months 

 time those steers took sick. He called a doctor and found that it 

 was the same as the lungworms the sheep had. ' ' 



"Maintenance of Size and Uniform Type," which was open for 

 general discussion was taken up by W. Z. Swallow, of Waukee, 

 Iowa, as follows : 



"I think there is quite a bit of room for talking on this subject. 

 I think the Poland China man more than any other breed has had 

 a great deal of experience. For a while they went for a small ani- 

 mal and then the next jump they wanted too big an animal. The 

 medium sized animal is the best I think. That has been my experi- 

 ence for about forty years. Just pick a nice sized animal and go
