"John the Baptist was a missionary, but his raiment was of camel's hair, and his food locusts and wild honey," was the answer.  "A man may be a first-rate missionary who dresses in a fustian jacket and leather gaiters, or whose costume is not more elaborate than that of these poor people.  A friend of mine told me that he has often, sitting hammer in hand on the roof of a cottage nailing on shingles, preached the gospel to a congregation who were as attentive as if he were in a high pulpit, and were habited in lawn sleeves."
