At hanau it was determined that Ab4-36 ended a season which probably can be defined as 140 days long. Then, at rima aueue, further light was cast on the strucure:

Ab4-36 Aa4-55

An overview shows the special nature of the 6th period (which our manu kake initiates), both henua and its sign at right are different from what we can see in the other 7 periods: 

1 5
Ab4-15 Ab4-20 Ab4-33 Ab4-42
2 6
Ab4-21 Ab4-23 Ab4-43 Ab4-47
3 7
Ab4-24 Ab4-28 Ab4-48 Ab4-57
4 8
Ab4-29 Ab4-32 Ab4-58 Ab4-62

A short repetition of some of what was said earlier:

... Manu kake in Ab4-43 is drawn slightly assymmetric. The left wing tip is not closed, the right wing is narrow and somewhat uplifted. The neck of the double bird is at right drawn with a broken line. These signs should indicate that midsummer lies in front, I guess. My guess finds support in hau tea at Ab4-49, because I believe its double 'eyes' function like a sign of Janus:

Ab4-48 Ab4-49 Ab4-50 Ab4-51 Ab4-52
Ab4-53 Ab4-54 Ab4-55 Ab4-56 Ab4-57

Furthermore, the 10 'feathers' in haś reasonably indicates that sun has reached an end. Haati at Ab4-50 probably means a season is leaving. Mauga (Ab4-55) means 'last', maybe of the first part of the year or possibly 'of the sun' - notice how the two forward flames in the hetuu glyphs are drawn 'broken' ...

Counting we find manu kake in Ab4-43 comes immediately before a number which seems to be a sign. 288 can be 'refracted' by the equation 4 * 44 = 2 * 88, and possibly it means that 8 months of moonlit nights (28) are ending:

Ab4-37 (281) Ab4-38 Ab4-39 Ab4-40 Ab4-41 Ab4-42
Ab4-43 Ab4-44 (288) Ab4-45 Ab4-46 Ab4-47

It should also be noted that the broken line at right in the neck of manu kake is the opposite sign to that in Ga3-1:

Ga3-1 Ab4-43

The broken line in Ab4-43 changes the figure from a real one in front of us into an abstraction, a ghost. With a broken neck (and a broken wing) you cannot live any longer. These two opposite signs support each other - with only one of them we would be tempted to dismiss it as a 'misprint'. Now we cannot. The extended vertical line at right in the neck of Ga3-1 should mean 'very strong'.
