Conclusion.

22. In conclusion I may say that the progress of vaccination in
the United Provinces has, in the triennial
period, not been inconsiderable, in spite of
having to contend with such a formidable adversary as plague. In the
nature of things vaccination must always be carried out among the most
uneducated classes, and among people suspicious to a degree. The work
of vaccination has been slowly built up, step by step, year by year, and
it says much for the confidence placed in officials, that even during a
period when plague has attacked the Provinces, no great falling off or
opposition to vaccination has been observed and that even a gratifying
increase in work can be shown.
