The usual occasion for the building of a new _emone_ is an impending big feast, the then existing _emone_ in the village being out of repair, or there being then no true _emone_ in the village. But _emone_ are built at other times also.
The actual building of the _emone_ is carried out by the whole clan without ceremony; but when it is finished they erect tall slender straight-stemmed tree poles, passing through the roof of the _emone_, and to these they tie bunches of croton leaves. When the _emone_ is being built in anticipation of a big feast, these poles are like, and in fact are part of the series of, the poles erected for the purpose of the feast, as above described. Croton leaves are also attached to poles after the repairing of a then existing _emone_.
In the case of a new _emone_, after its completion they light a fire in it, and in that fire cook a wild pig; vegetable food is provided, and the clan, including members of the village and of other villages, have a little clan feast of the vegetables, followed by a cutting up and distribution of the pig. But there is no dancing.
A boy is regarded as having reached a marriageable age at about 16, 17, or 18, and the age for a girl is a few years younger. They do not as a rule marry before they have received their perineal bands; but there does not appear to be any definite custom against their doing so; nor are there any acts which must be performed to qualify for marriage, nor any indications by dress or ornament or otherwise that a boy or girl has attained a marriageable age.
Marriages are usually contracted with women of another community, though sometimes the wife will belong to a village of another clan in the same community. Very rarely only is she of another village of the same clan, and still more rarely is she of the same village, clan exogamy being the rule, and marriages within the clan, and still more within the village, being regarded as irregular and undesirable, and people who have contracted them being considered as having done wrong.
There does not appear to be any system of special matrimonial relationship between any communities; and the mode described below, by which a youth will by lighting a fire decide in which direction he must travel to seek a wife, would be hardly consistent with any such system.
