cattle the principle of the Bertillon system of identification. Each 
inspector is provided with forms giving in profile the figure of a cow, 
right and left sides, and containing a space for descriptive memo- 
randa. The forms are small, so as to be easily carried in the in- 
spector’s pocket. On such a form the inspector notes the charac- 
teristic marks of the cow condemned, and the time and place of 
condemnation. The inspector subsequently carries this form with 
him for a reasonable time, so that if he finds anywhere a cow that 
seems to resemble a cow that he has condemned he can confirm or 
allay his suspicions. 
The law regulating the issue of permits to dairy farms outside of 
the District provides that they shall be issued whenever the health 
officer is satisfied that the milk from the farm that is about to be 
licensed will be brought into the District without danger to public 
health. Since it has been so clearly demonstrated that milk from any 
herd that has not been tuberculin tested is dangerous to public health, 
unless effectually pasteurized, the health officer has found it im- 
practicable to issue permits to bring or send milk into the District 
from such farms. But as the law permits any applicant to bring or 
send milk into the District from the time he files application and 
until his application has been rejected, the health officer has, in those 
cases where the applicant has complied substantially with all require- 
ments of the District laws and regulations, suspended indefinitely 
action on the application pending the adoption of some general meas- 
ure looking toward the compulsory tuberculin testing of all cows sup- 
plying milk to the District of Columbia or, as an alternative, the com- 
pulsory pasteurization of milk from cows not so tested. 
Each inspector of dairy farms files with the health officer, weekly, a 
report of his operations for the preceding week.® In addition to this 
he keeps his own record of outstanding notices, and as soon as prac- 
ticable after the expiration of the time allowed for the correction of 
objectionable conditions he visits the premises to see whether the notice 
has or has not been complied with. If it has been, the inspector 
makes report accordingly. If it has not, he takes action to enforce 
compliance. He may immediately serve a notice requiring the licensee 
to show cause, satisfactory to the health officer, why his permit should 
not be canceled. Or he may recommend that a letter of that purport 
be written by the health officer . * 6 Or, if the farm be located in the 
District, he may recommend immediate prosecution in the police court, 
and with the approval of the health officer he may institute such prose- 
cution. If a licensee has been notified to show cause why his permit 
should not be canceled, and has failed to do' so, or has shown no 
sufficient cause, then the health officer cancels the permit and notifies 
a See form for report on page 802.
