388 IOWA DEPARTMENT OF AGRICULTURE 
We have also traced back tuberculous conditions to localities where 
they were least suspected, and after examination, have lound we v.-ere 
justified in making the tuberculin test, and preventing through quarantine 
measures, any further spread of the disease. The reports above referred 
to are filed in this office and under constant surveillance, so that in the 
event that they are of a serious nature, we are able to jjrevent outbreaks 
of any other surrounding stock. We have been favored with the ro-opera- 
tion of the management of packing houses, owners of shi;jpins sto^k and 
shippers in suppressing any spread of disease, and also, in disinfecting 
premises and stock cars where disease is known to have existed. 
THE BUREAU OF ANIMAL INDUSTRY. 
There is no wider range of identification of the live s'^ock interests 
of this country, than that originating through the Bureau of Animal In- 
dustry. An efficient corps of inspectors under the managemant of a fhief 
inspector at Y/ashington, is always in close touch with the stock shipnipnts 
originating throughout the United States. Iowa has had no small part 
of shipments to eastern markets. The inspector at such points or yards, 
where the Iowa cattle are unloaded, also makes a thorough investigation 
of their condition, and we have had but few reports dercgatory to the 
welfare of our cattle shipping interests. 
The Bureau of Animal Industry file with this department a list of tha 
names and addresses of all Iowa shippers, number of animals shipped, 
points of destination, and finally, the last post mortem reports on such 
animals. These reports originating in Washington, and forwarded under 
the authority of the chief of the inspection division, are on file in this 
office. 
During the past three years, there have been few other diseases out- 
side of tuberculosis and scabies reported, and these were found to be of 
an incipient form only. The Bureau of Animal Industry also have super- 
vision over the inter-state shipments, and the shipment of breeding and 
dairy cattle into other states. There is a stringent law prohibiting the 
shipment of infected stock and this law is enforced, inasfar as the juris- 
diction of the inspectors will admit. We have had cases where an effort 
has been made to ship diseased stock from Iowa into other states, and 
through the Bureau of Animal Industry we have learned of this effort, 
and prevented such violation of the law. In this connection, we also 
received through a joint circular issued by the Western Trunk Line Com- 
mittee of Chicago, information as to the quarantine rules and regula- 
tions applied to state and inter-state traffic, and under supervision of the 
railway company's transporting stock; also governing the location of un- 
loading or feeding points upon the route or any cross-country shipments. 
Such unloading or feeding pens are subject to disinfection, etc., to pre- 
vent the existence or spread of any disease. 
These reports are kept on file in this office for reference at any time.
