t fense begins when he brings or sends milk into the District without a 
f permit to do so ; but his permit, if he has one, is by law conditioned 
p upon the management of his farm in accordance with the laws of the 
District in so far as those laws do not conflict wuth state laws; and, 
t' therefore, if his farm presents circumstances in violation of law, the 
i conditions upon which his permit was issued have been violated by 
I him, and his permit becomes voidable at the election of the health 
officer, even if it does not become actually void. AAdien a dairy farm 
is located be3mnd the limits of the District, compliance with District 
J laws and regulations is enforced, therefore, not by immediate crim- 
I inal prosecution, but b}^ the cancellation of the permit, if necessaiw, 
^ and then if the milk from the tabooed farm is brought into the Dis- 
* trict, by criminal prosecution of those responsible for the importation 
y of the milk — the farmer who sends it in, if he can be found in the 
t jurisdiction, or the dealer who contracts with the farmer to have the 
5 law violated and cooperates with him in its violation, or both farmer 
i. and dealer. Unless, however, the violation of the regulations is ex- 
} tremely grave, or unless similar offenses have been of repeated occur- 
\ rence, summar}^ action is not taken, but the offender is given an op- 
portunity to correct conditions, or at least given an opportunity, if 
: he be a nonresident, of showing cause wlw his permit should not be 
i canceled. If he be a resident of the District, even after final action 
by the health officer, he has his da}^ in court. 'What has been said 
j with reference to the cancellation of permits has had reference to 
cancellation because of the existence of insanitaiy conditions. Per- 
t mits may be suspended or revoked, whether the farm be within or 
without the District, if the milk suppl}'^ therefrom is exposed to in- 
fection b}^ certain contagious diseases, but this is a matter that will 
be considered later.® 
If, then, an inspector of dair}^ farms has found conditions that 
must be corrected, he serves a notice on the responsible person requir- 
' ing him to correct them within a specified period, or if the conditions 
[ are particularly bad, he may, if the farm is within the District, rec- 
t ommend immediate prosecution in the police court, or, if the farm is 
, located outside of the District, he may serve at once a notice requir- 
i ing the licensee to show cause on or before a given day, to the satis- 
I faction of the health officer, why his permit should not be canceled.^ 
I If the farm be one for which no license has been issued, but for 
I which application is pending, then, if the circumstances warrant such 
■; action, the inspector may recommend the immediate rejection of the 
application. Any notice prepared by the inspector is written in 
duplicate by means of carbon paper, the original being left on the 
premises and the carbon cop3^ being forwarded to the health officer so 
as to reach him on the dav following the day of service.
