and far between. A certain part of the inspector’s time, too, not 
infrequently goes for naught during the summer season, when, if the 
cattle are to be examined, he must wait for them to be brought up 
from the pasture. And at any time of the year a careful inspection of 
a dairy herd of any considerable size, including, as it must, an exami- 
nation of the udders and lungs, of itself consumes a considerable time. 
In the most thickly settled parts of an inspection district an inspector 
may make six or eight inspections in a day. In remote regions he 
may be able to make but two and possibly only one. The records of 
the department show that the average number of dairy farms visited 
daily by one inspector during the fiscal year ended June 30, 1909, was 
2.7, the computation being based upon the work of the six inspectors 
then on duty and on the actual number of days worked by the entire 
force on the inspection of dairy farms, viz, 1,589. The average 
frequency' with which each of the 864 dairy farms actually inspected 
was visited during the period named was 4.9. 
An inspector assigned to an outlying district is required to live 
within the territory under his supervision. Thus, one inspector 
resides at Leesburg, Va., another at Germantown, Md., and a third at 
Frederick, Md. The inspectors having supervision of the three dis- 
tricts adjacent to the city, and in fact extending within it, reside in 
Washington. The number of dairy farms now under the inspection 
of each of these inspectors is as follows : 
Washington district No. 1 
Washington district No. 2. 
Washington district No. 3 
Leesburg district 
Germantown district 
Frederick district

The local inspectors of dairy farms ordinarily visit the health 
office each morning to file reports of the preceding day’s work and to 
receive instructions as to their duties for the day. If, however, an 
inspector expects to go a long distance during the day, in order to 
visit an outlying farm, this customary visit may be omitted. The 
inspectors residing at Leesburg, Germantown,' and Frederick, under 
ordinary circumstances, visit the health office but once each month, 
forwarding to the health officer by mail daily such reports as may be 
necessary, and receiving their instructions in like manner. In any 
event, each day, either after visiting the health office, if a visit be 
required, or without such a visit if none be necessary, the inspector 
proceeds to examine certain of the dairy farms hung within the ter- 
ritory assigned to him. In determining which of these farms to visit 
he is guided by instructions from the health officer, by outstanding 
notices which he has served, and by a general knowledge of the condi- 
tion of the farms within his district. It is just here that the services
