number of unimals attacked. That this would be a result of 

 the new Order was foreseen. Under the old procedure, when 

 one horse in a stable developed obvious symptoms of glanders, 

 and simple inspection of the other horses revealed no other 

 cases, the outbreak was reckoned to be at an end as soon as the 

 diseased horse had been killed. Thus it often happened that 

 an outbreak was returned as having only one animal attacked, 

 because in the absence of a mallein test the inspector obtained 

 no knowledge of the horses in the incubative stage of the 

 disease. If one of these, after an interval, became clinically 

 glandered the outbreak figured in the returns as a new one. 

 Under the present procedure, on the other hand, each outbreak 

 includes not only the first detected clinical case but also the 

 cases that are immediately afterwards detected by applying the 

 mallein test to the apparently healthy horses. 



Although the effect which the present Order has produced 

 is very striking and not less than an intelligent consideration 

 of the circumstances would have led one to expect, it may still 

 be some years before glanders is absolutely stamped out. 

 Obviously such radical measures as are now in force are likely 

 to show the most striking results at the outset, when the 

 disease is widely prevalent, and they may appear to act more 

 slowly after the first marked reduction has been effected. 

 It is, however, very encouraging to observe that the ratio of 

 decrease in the number of outbreaks during 1911 is not less 

 than that of the preceding year. 



Swine Fever. 



The following Table shows the number of reported out- 

 breaks of this disease during each of the last six years : — 



Year Outbreaks 



1906 1,280 



1907 2,336 



1908 2,067 



1909 1,650 



1910 1,598 



1911 2,466 



The above Table is the unfortunate offset to the success 

 which has attended the operations of the Board of Agriculture 

 and the local authorities in dealing with the other contagious 

 diseases of animals during the past year. 



In order to appreciate properly the present position with 

 regard to swine-fever it is necessary to go farther back than 

 the period covered by the Table. Between the years 1879 and 

 1893 the disease was dealt with by the local authorities under 

 the Contagious Diseases (Animals) Act. During that period 

 the smallest number of reported outbreaks in any one year was 

 1,717 (in 1881), and the largest G,813 (iji 1886). The smallest
