than in the collection of crystalised, ethnographic data. But here also the main endeavour must be to let facts speak for themselves. If in making a daily round of the village, certain small incidents, characteristic forms of taking food, of conversing, of doing work (see for instance Plate III) are found occurring over and over again, they should be noted down at once. It is also important that this work of collecting and fixing impressions should begin early in the course of working out a district. Because certain subtle peculiarities, which make an impression as long as they are novel, cease to be noticed as soon as they become familiar. Others again can only be perceived with a better knowledge of the local conditions. An ethnographic diary, carried on systematically throughout the course of one’s work in a district would be the ideal instrument for this sort of study. And if, side by side with the normal and typical, the ethnographer carefully notes the slight, or the more pronounced deviations from it, he will be able to indicate the two extremes within which the normal moves.
In observing ceremonies or other tribal events, such, for instance as the scene depicted in Plate IV, it is necessary, not only to note down those occurrences and details which are prescribed by tradition and custom to be the essential course of the act, but also the Ethnographer ought to record carefully and precisely, one after the other, the actions of the actors and of the spectators. Forgetting for a moment that he knows and understands the structure of this ceremony, the main dogmatic ideas underlying it, he might try to find himself only in the midst of an assembly of human-beings, who behave seriously or jocularly, with earnest concentration or with bored frivolity, who are either in the same mood as he finds them every day, or else are screwed up to a high pitch of excitement, and so on and so on. With his attention constantly directed to this aspect of tribal life, with the constant endeavour to fix it, to express it in terms of actual fact, a good deal of reliable and expressive material finds its way into his notes. He will be able to “set” the act into its proper place in tribal life, that is to show whether it is exceptional or
