These smaller seasons have seldom developed into an annual cycle otherwise than among some agricultural peoples[227], unless they have been fitted into the larger seasons. This is the case with the western tribes of the Torres Straits, who also determine the seasons from the stars. In the counting of the seasons they commonly begin with _surlal_ (mid-October to the end of November). This name is given to the turtles when copulating: while in this state they float on the sea and are readily caught. The constellation known as the Shark arises. Everything is dried up, the yams are ripe. The sounding of the first thunder is the sign for planting yams. _Raz_ (December to February) is described as ‘the time of death’, i. e. the season when the leaves die down. The first part of this season is called in Mabuiag _duau-urma_, ‘the falling of the cashew nuts’. There is an interval of fine weather and the wind is shifty: this coincides with Christmas-time. This is the time when the yams which have been planted begin to sprout. In Muralug this period is called _malgui_, which is the exact equivalent of our word ‘spring’. The next division is called _dob_, ‘the last of growing things’, or _kusikuki_, ‘medusae of the north-west’, the latter name being due to the large numbers of jelly-fish that float on the sea. The runners of the yams now grow. The time immediately after this is called _purimugo_, in Muralug _apagap_ or _keme_. The longer season following _raz_ is _kuki_, (March to May), the time when strong winds blow intermittently from the north-west, accompanied by deluges of rain, and the time of the damp heat. The appearance of the constellation _dogai kukilaig_ (Altair, together with β, γ _aquilae_) heralded the beginning of this season. It has the sub-divisions _kuki_, _kupa kuki_, and _gugad arai_. The dry season, _aibaud_, forms the remaining part of the year. The south-west wind, _waur_, blows steadily: for this reason the first part of this period is known as _waur_ and perhaps merits a distinctive name as much as _raz_. It is marked by the appearance of the constellation _magi Dogai_ (Vega with β, γ _lyrae_). Food is abundant and festivals are celebrated. The divisions of _aibaud_ are _sasiwaur_ (‘child’, i. e. lesser south-east), _piepe_, _tati waur_ (‘father’, i. e. greater south-east), and _birubiru_, a bird which at this time migrates from New Guinea to Australia[228].
