trol over the interstate traffic includes also an 
authority over the strictly intrastate transporta- 
tion. 
128. Departmental Veterinarians. Inspectors 
are appointed by the department after a civil serv- 
ice examination, to which are admitted only the 
graduates of veterinary schools of approved stand- 
ing, having courses of at least three years before 
a degree is conferred. These inspectors supervise 
the shipment and inspection of the cattle, and 
their final slaughter for interstate and foreign com- 
merce, and make the necessary post mortem exam- 
ination. 
129. General Quarantine Regulations. Under 
the acts of 1884, 1903 and 1905, whenever the Sec- 
retary of Agriculture shall determine that the live 
stock of any section are infected with a contagious 
or infectious disease, it becomes his duty to declare 
a quarantine, either upon the entire state, or upon 
such portion as may seem advisable. In so far as 
the state quarantine area seems sufficiently pro- 
tective it is the custom of the Department to adopt 
the same. The transportation or driving of quar- 
antined animals from the quarantine area, or the 
permitting them to drift, is strictly prohibited, 
except under regulations approved by the depart- 
ment. All pens, or means of conveyance, which 
have been used by infected animals, or by those 
exposed to infection, must be thoroughly disin- 
fected by approved methods before they are used 
for other animals. This includes also feeding pens, 
stockyards, chutes and alleys used by infected or 
exposed animals. When deemed necessary, the 
interstate shipments of live stock will be stopped
