these questions, though well recognised as a social form, is not
in practice strictly adhered to. Also A, on coming to a village and
finding B there, and wishing to salute him, will call him by name,
and B will then call A by name. Then A will say, "You are here,"
and B will reply, "I am here." This form is more strictly carried
out than is the other one. Then when A leaves he will say to B,
"I am going," and B will answer, "Go." Then B will call A by his
name, and A will call B by name, and the formality is finished. If A,
being very friendly with B, comes to his village to see him, on A's
departure B, and probably B's family, will accompany A out of the
village, and will stand watching his departure until he is about to
disappear round the corner of the path; and then they will call out
his name, and he will respond by calling out B's name.

Gestures may perhaps be included under this heading, though there is
apparently but little to be said about the matter. When a question
is asked, an affirmative reply is indicated by nodding the head,
and a negative one by shaking it; and, though I asked if this was
not probably the result of association with people who had been among
white men, I was told that it was not so. A negative answer is also
often expressed by shrugging the shoulders, and a kind of grimace
with the lips. The nodding of the head to a negative question, such
as "Are you not well?" signifies assent to the negative, that is,
that he is not well, and so vice-versa with the shaking of the head.
