educational efficiency: efficiency should increase evangelistic power.]

One result of the sharp distinction which is drawn between medical and
educational and evangelistic work is that in some countries there are
distinct medical and educational associations which collect information
about the state of medical and educational missions in the country,
dealing with these missionary activities most prominently, if not
wholly, from the point of view of medical and educational efficiency.
These associations issue _questionnaires_ and publish reports often more
full, detailed, and carefully compiled than any evangelistic reports.
Consequently it is peculiarly dangerous for a layman unacquainted with
the working of these associations to trespass upon their preserves.
These departmental surveys should be treated separately by experts.
Nevertheless, since we are dealing with the work of the station in its
area, and this work includes often medical and educational work, we
cannot pass over it with no more than the general treatment which we
have hitherto given. We need to know what is the medical and what the
educational work carried on at the station, when these are viewed, as
they are viewed, separately, as distinct expressions of missionary zeal.

Dealing first with medical missions we suppose that the question might
be put in this form, What are the medical missionary resources available
in the district in relation to the need which it is proposed to meet?

Here again there arises the difficulty that there is no common agreement
as to the purpose of the medical work of the missionary societies. What
are the doctors there for? What does the hospital exist to do? Who can
tell? So diverse are the ideas of different men on this subject, so
little thought out, that a man of unusual experience told us that he had
met few missionary doctors who could answer the question: "On the basis
