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.
