of war), since wars are chiefly fought in this season. When it stands over the equator, the season is called _morai in houas_ (sun of friendship), the season of friendship and mutual visits. When the sun turns towards the south, the cooler season begins[355]. Of the Kiwai Papuans of the islands in the delta of the Fly River in New Guinea, Torres Straits, Landtman writes to me that he cannot say if the people are clear whether they reckon in years or in half-years[356]. The former supposition is really only supported by the fact that they are aware that the same natural conditions recur after the lapse of the two half-years. There is no word for year. On the whole it may be said that they count only the months, and hardly conceive of so great a unit as the year, nor even (at least not everywhere) of the half-year, although there may be a hint of this in special cases. Not seldom the dry and the rainy seasons are counted without being combined into a year. This is expressly stated of the Tupi of Brazil and certainly applies also to the Bakairi[357]. In Loango there are dry and rainy seasons, and in many districts a third season also, the fruit-ripening. Commonly the people reckon by the two main seasons. A centenarian is therefore fifty years old[358]. In Uganda there are in the course of twelve months two rainy and two dry seasons, although there is hardly a month in which no rain falls at all. The rainy season from February to June is called _togo mukazi_, since the rain then falls without much thunder: the second, from August to November, is called _dumbi musaja_, because of the thunder and the frequent deaths from lightning. The dry season about December is more intense than that about June. However the year, _mwaka_, is composed of one rainy season together with the following dry season, and consists of six moons or months[359]. Their year, corresponding to a half-year, consists of five moons, and a sixth in which it rains[360]. In north Asia the common mode of reckoning is in half-years, which are not to be regarded as such but form each one separately the highest unit of time: our informants term them ‘winter year’ and ‘summer year’. Among the Tunguses the former comprises 6½ months, the latter 5, but the year is said to have 13 months; in Kamchatka each contains six months, the winter year beginning in November, the summer year in May; the Gilyaks on the other hand give five months to summer and seven to winter. The Yeneseisk Ostiaks reckon and name only the seven winter months, and not the summer months[361]. This mode of reckoning seems to be a peculiarity of the far north: the Icelanders reckoned in _misseri_, half-years, not in whole years, and the rune-staves divide the year into a summer and a winter half, beginning on April 14 and October 14 respectively. But in Germany too, when it was desired to denote the whole year, the combined phrase ‘winter and summer’ was employed, or else equivalent concrete expressions such as
