the sick, the suspected, and the healthy, there is little or no
danger of establishing a focus for the dissemination of the
disease, while the control of the guard can be made effective
and malpractices on the part of the subordinate establish-
ments be prevented if European agency is employed on the
spot to supervise such establishments, and to check, by a
system of registering the inmates of the camps, the attempts
which may be made to leave them.
11. In accordance with the principles explained above,
the Government of India have restricted the interference with
the movement of the general public by railway to medical
inspection. In the terms of the Venice Convention medical
intervention is restricted to the inspection of travellers with
a view to the detention of those who show symptoms of
plague and to the care of the sick. The Convention also
dwells on the desirability of keeping under supervision all
travellers from an infected area at their homes for a period of
ten days from the date of their departure from the infected
area. The Government of India approve of the medical
inspection being conducted so as to provide for the detention
in the observation camp provided for this purpose not only of
persons in whom symptoms of plague or suspicious symptoms
are discovered, but of all persons from the infected area who
appear to be suspicious by reason of their appearance, the
dirty condition of their clothes, the fact that they are travel-
ling in gangs or belong to classes which are likely to dissemi-

destination or depended upon to give information should
plague occur among them after arrival at their destination.
All other persons should be allowed to proceed to their
destination after inspection, and the rules should not, under
any circumstances, exempt from their operation any class
of persons as such, or be limited to persons who travel by
railway by a particular class.
12. While these are the general principles which should
guide the different Local Governments and Administrations in
their control over the movements of the general public travel-
ling by railway from an infected area it may often be advisable
to interpose special checks either on the movement of pilgrims
from an infected area to a place of pilgrimage beyond that
area, or on the movement of pilgrims to a place of pilgrimage
at which plague exists. When plague exists at a place of
pilgrimage it may indeed be generally the most prudent course
as well as the course which will in the end cause least inter-
ference with the people to definitely prohibit the religious fair
