scopical and bacteriological examinations confirmed this similarity, and 
the mallein and agglutinations test applied to three horses showing 
typical symptoms, proved beyond a doubt that the disease was glanders. 
We watched subsequent developmests and by means of further micro- 
scopical examinations, concluded that Mr. Parrell had suffered and died 
of glanders, as transmitted to him by the diseased horses he had attended. 
Just after Mr. Farrell's demise, we secured the photograph shown on 
the opposite page, and the result of glanders, in the human form, may 
readily be seen. 
HOG CHOLERA. 
With the exception of the past two years, we have had less cholera 
than in any former period. The heaviest losses sustained thoughout this 
country, occurred several years ago. Quarantine methods and regula- 
tions to keep under control the existence of any outbreak, have been the 
only way and means of preventing losses. 
Possibly the most prominent avenues from w^hich cholera is known 
to originate and spread, is through improper disposition of dead hogs. 
Birds are known to carry infection from one place to another, after having 
been around an animal which has succumbed to the disease. It is also 
believed that droppings from railway cars, or contagion beginning at 
public sales or markets, fairs, etc., have had to do with spreading the 
disease. 
One gratifying report we have to make as related to our swine industry 
is that we have had very few cases of contagion reported among stock 
shipped to any state or county fair for exhibition purposes. When we 
take into consideration the fact that Iowa has had as many 3,100 hogs on 
exhibition at our State Fair, and also the fact that Iowa is the largest 
hog raising state in the Union, we have a right to expect more or less 
contagion. It is true that the other states seldom have more than 1,000 
hogs exhibited at one time, and yet these states have rigid rules and 
regulations to prevent the importation of any stock for exhibition pur- 
poses to their state fair. Some of our stock men were much concerned 
last year over the possibility of being barred from outside exhibitions 
on account of contagion among swine, but fortunately this has never 
occurred, and it is partly due to the careful manner in which these ani- 
mals are cared for and protected from infection. At the last session of 
the legislature, in order to identify the township and county health or- 
ganizations with their due responsibilities, included in connection with 
other laws enacted, the duty of local boards of health to take action 
wherever and whenever they were informed of any contagious disease 
among domestic animals in their locality, and to co-operate with the state 
veterinarian and serve him with notice of such disease promptly upon its 
discovery. This not only applied to hog cholera, but to all other infectious 
diseases among live stock. While this regulation has not been fully com- 
plied with, it is true that there have been a large number of important 
calls come to this department through this means. We have appreciated 
tne immediate attention given by many of these boards, and cannot too 
strongly urge others to follow their example, in order that public safety 
of live stock may better be conserved.
