This quotation from Mr. Clark lands us in another subject, and one of no small importance. Charlotte Tucker, going as she did to India when well on in middle life, looked upon herself as a possible Pioneer, a possible example to others, and hoped that many more might be led to do the same. But she was never under the delusion that anybody and everybody is fitted for a Missionary life,--even granting the spiritual adaptedness. There must be of course whole-hearted devotion to Christ, whole-hearted love to man, and whole-hearted self-abnegation; but there must also be certain natural capabilities, certain conditions of health and vigour. Beyond all, there must be the Divine call to work in the Mission-fields. All this Charlotte Tucker felt with increasing earnestness as years went on; and she was often at pains to explain the kind of workers wanted out there, to warn against the kind of workers _not_ wanted.
