GOVERNMENTAL SERVICES 161 
is over interstate commerce, not intrastate, and 
when it is practicable to quarantine against a por- 
tion of a state, rather than against an entire state, 
the Secretary of Agriculture has that authority. 
The federal local inspector, in so far as he is en- 
forcing interstate quarantine is a federal officer; 
but his federal authority does not cover services 
in maintaining intrastate quarantine. Since his 
authority does not cover such work, neither should 
he be considered as under the protection of the 
federal courts in matters outside of his authority, 
unless, possibly, there be an attempt on the part 
of the state government to personally restrain him 
from the performance of his real official duties.
