EIGHTH ANNUAL YEAR BOOK— PART VI. 245 



it and then going over the ground with the disinfectant with a 

 spray pump and using lime and then white-washing after you 

 have disinfected, we think that is all you can do. Don't think that 

 once disinfecting lasts forever. Keep doing it. It is a good habit 

 to disinfect from time to time. You will keep away all diseases 

 and prevent them by using this method. If j'our pigs become 

 affected with scabies or any of the minor skin affections make a 

 small dip tank, or if that is too much expense, simply catch the 

 pigs and take some disinfectant and a scrub brush and clean up 

 their faces and heads. Get all the matter away and then paint 

 them with a little iodine. That helps to disinfect. This should 

 be done from time to time. 



At this point a somewhat scattered discussion of the presence 

 of tuberculosis in cattle took place but as it brought out no new 

 facts and is only indirect in its bearing upon the hog industry, 

 it is omitted from this report. 



The evening session opened with a paper by R. S. Johnson of 

 Columbus Junction, on The Iowa State Fair and Its Object: the 

 Duties and Privileges of Exhibitors. Mr. John.ston is superintend- 

 ent of the swine department of the Iowa state fair.

 subject for us to fire at. But one satisfaction is that we can dodge around 

 a good deal without getting off the subject. To my mind there are four 

 distinct subjects under the above headings, which we divided as follows: 

 The Iowa State Fair, Its Object, the Duties of Exhibitors, and the 

 Privileges of Exhibitors. 



Laclv of time has prevented me from giving the subject the careful con- 

 sideration I would like. While I will have all the exhibitors of the Iowa 

 State Fair in mind, I shall have those in the swine department particularly 

 in view. 



Preparations are now being made for the holding of the fifty-third 

 annual State Fair. Never in its history was there so many improvements 

 under way in one year as at the present time. Something over one hun- 

 dred thousand dollars will be expended in permanent improvements this 

 year. Of this amount seventy-five thousand dollars was granted by the 

 last Iowa legislature for the swine building, and nearly six thousand dol- 

 lars by the same legislature for the purchase of ground upon which the 

 swine building is being erected. The balance that is being expended is 

 the surplus of the fair itself, which will amount to perhaps thirty thou-
