The harvest of the main gardens inaugurates a long and elaborate series of activities, associated with the offering of annual gifts. The members of each household — for digging is always done en famille — repair to their own garden-plot within the large, communal enclosure.

Then a selection is made. The best yams are placed in a large conical heap in the middle, and this is the urigubu yield (see pl. 27). The rest are stowed away in the corners in less regular and much smaller heaps. The main heap is constructed with almost geometrical precision, with the best yams carefully distributed all over its surface, for it will remain in the little shed for some time, to be admired by people from the village and neighbouring communities. All this part of the work, which, as can easily be seen, has no utilitarian value, is done eagerly, with interest and con amore, under the stimulus of vanity and ambition. The chief pride of a Trobriander is to gain renown as a "master-gardener" {tokway-bagula).
