Polaris (Ana-nia) was a place 'to fish by' and in Roman times Land (Aries) would here have been 'fished up' from the depths of the sea. Coconut trees were thriving at the border between Land and Sea. And Polaris, which came 26 days after Sirrah, marked the end of side a on the C tablet. 392 = 366 + 26.

As to huki this too had to do with fishing:

Huki 1. Pole attached to the poop from which the fishing-net is suspended: huki kupega. 2. Digging stick. 3. To set vertically, to stand (vt.). 4. Huki á te mahina, said of the new moon when both its horns have become visible. Vanaga. 1. To post up, to publish. 2. To cut the throat (uki). Mq.: Small sticks which close up the ridge of a house.

A singular coincidence of application, if it has no nearer connection, by the Polynesian and the Latin of this word to similar purposes, occurs in the huhui and hui-tarawa of the former and jugulæ of the latter. In Hawaiian huhui designates a constellation generally, but especially that of the Pleiades; in Tahitian hui-tarawa, lit. the transverse or horizontal cluster, designates the stars generally called Orion's belt, and in Latin jugulæ represents the very same stars in the constellation Orion.  HUI², v.

If a Tree was perceived to rise up at the horizon in the east, then it ought to have come up at the time when the 'Land' of the 'summer year' was arriving.

 

... In north Asia the common mode of reckoning is in half-year, 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. 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 'in bareness and in leaf', 'in straw and in grass' ...

This Land could be 'fished up' (the head of the 'Fish' arriving first and its tail later) and the Tree surely had to stand on Land.

 

... Boastful Maui behaved as if it were a very ordinary sort of fish-hook, and flashed it carelessly. Then he asked his brothers for some bait. But they were sulking, and had no wish to help him. They said he could not have any of their bait. So Maui atamai doubled his fist and struck his nose a blow, and smeared the hook with blood, and threw it overboard. 'Be quiet now,' he told his brothers. 'If you hear me talking to myself don't say a word, or you will make my line break.' And as he paid out the line he intoned this karakia, that calls on the north-east and south-east winds: Blow gently, whakarua, / blow gently, mawake, / my line let it pull straight, / my line let it pull strong. / My line it is pulled, / it has caught, / it has come. / The land is gained, / the land is in the hand, / the land long waited for, / the boasting of Maui, / his great land / for which he went to sea, / his boasting, it is caught.

 

A spell for the drawing up of the world. The brothers had no idea what Maui was up to now, as he paid out his line. Down, down it sank, and when it was at the bottom Maui lifted it slightly, and it caught on something which at once pulled very hard. Maui pulled also, and hauled in a little of his line. The canoe heeled over, and was shipping water fast. 'Let it go!' cried the frightened brothers, but Maui answered with the words that are now a proverb: 'What Maui has got in his hand he cannot throw away.'

 

'Let go?' he cried. 'What did I come for but to catch fish?' And he went on hauling in his line, the canoe kept taking water, and his brothers kept bailing frantically, but Maui would not let go. Now Maui's hook had caught in the barge-boards of the house of Tonganui, who lived at the bottom of that part of the sea and whose name means Great South; for it was as far to the south that the brothers had paddled from their home. And Maui knew what it was that he had caught, and while he hauled at his line he was chanting the spell that goes: O Tonganui / why do you hold so stubbornly there below? / The power of Muri's jawbone is at work on you, / you are coming, / you are caught now, / you are coming up, / appear, appear. / Shake yourself, / grandson of Tangaroa the little ...
