It is quite true.

In the last resort survey becomes survey of personalities.

But in a survey of the kind which we propose, survey of personalities is impossible and most undesirable.
The survey proposed cannot deal with personalities, but that does not invalidate the importance of the information asked for.

Such forms received from many different stations would certainly throw light on the serious question of reinforcement.

It is of course obvious that reinforcements could not be allotted rightly on such slight evidence as the proportion of missionaries to the population of a district.
