FIFTEENTH ANNUAL YEAR BOOK — PART V 399 



source of protein meat meal can be fed with perfect safety if purchased 

 from a reputable manufacturer. Also the quality of the tankage should 

 be looked to; unscrupulous dealers frequently attempt to substitute a 

 low grade of tankage intended for fertilizer for the higher grade manu- 

 factured for feeding purposes. 



Mr. Cyrus Tow, Norway, Iowa, superintendent of swine at the Iowa 

 State Fair, then greeted the members of the association. He declared 

 his intention of providing for the exhibitors of swine at the state fair 

 every convenience and comfort which his best efforts could secure for 

 them, and solicited suggestions for the management of the swine depart- 

 ment at the 1914 show. 



Mr. McPadden, secretary of the American Poland China Association, 

 gave a short address which was pregnant with the promise of prosperity. 

 An office such as the one managed by Mr. McFadden is a fairly good bar- 

 ometer of the pure-bred swine business, for interest in any one breed 

 stimulates interest in all. The barometer shows a raise. In the face of 

 the affliction and disaster which have this year confronted the swine in- 

 dustry each month has seen an increase in registrations, of Poland-China 

 swine and in December it was greater than a year ago; 1913 was the 

 third largest year's business ever conducted. Interest is spreading into 

 the far West to a remarkable degree. There are now on file in Mr. 

 McFadden's office orders for three car loads of pure-bred swine, one to 

 Canada, Tennessee and Washington. 



During the evening the association members met in conjunction with 

 the short-course students in the agricultural assembly. In an excellent 

 program of four addresses, lasting two hours, swine cholera, the "black 

 beast" of the hog raiser, was set upon and conspired against. Dr. W. B. 

 Niles drove the beast into the open by a thorough going over of the 

 ground; Dr. C. H. Stange, director of the state serum laboratory, dis- 

 played the weapons with which to attack him; J. S. Thatcher, manager 

 of lowana Farm, described an engagement with the beast, in which the 

 enemy was defeated, and Prof. W. J. Kennedy, director of the exten- 

 sion department, connived and plotted for his complete extermination. 



Dr. Niles' address was in the nature of a general survey; the nature, 

 methods of contagion, symptoms and remedies were given. Dr. Stange 

 described the serum plant and the manufacture of serum; he also pointed 

 out the utter inability of the state serum plant as it is now equipped to 

 produce enough serum to supply one-seventh of the hogs of Iowa. The 

 plant has sent out serum to 1,200 herds of hogs and has over a million 

 cubic centimeters of serum in its store rooms. In only three cases was 

 loss in these herds serious after the administration of the treatment. 

 In one of these cases death proved to be due to worms; in one case the 

 disease was present, unrecognized, and the third case is being investi- 

 gated.
