Only two hipu glyphs remain before we reach Hanga Te Pau, and they differ in having 'feathers' and a little knob at bottom: Gb2-27 Gb3-30 Gb4-17 Gb4-30 Gb5-3 Gb5-12 They both are located at Hatinga Te Kohe (12 * 29.5 = 354): Gb4-21 (28.5) Gb4-22 Gb4-23 Gb4-24 Gb4-25 Gb4-26 Gb4-27 (29) Gb4-28 Gb4-29 Gb4-30 Gb4-31 Gb4-32 Gb4-33 (29.5) Gb5-1 Gb5-2 Gb5-3 Gb5-4 Gb5-5 Gb5-6 (30) Gb5-7 Gb5-8 Gb5-9 Gb5-10 Gb5-11 Gb5-12 (30½) Gb5-13 Gb5-14 Gb5-15 Gb5-16 Gb5-17 Gb5-18 (31) Gb5-19 Gb5-20 Gb5-21 Gb5-22 Gb5-23 They clearly belong together: 4 + 3 'feathers', 3 glyphs away from 354, and they are followed by two quite similar glyphs. But we will not investigate their meaning here. The proper place is at the hua glyphs: hua

The transformation into a 'feathery' stage is maybe hinted at in Gb4-16, the first of 18 glyphs necessary to go from 12 * 28 to 12 * 29.5:

Gb4-13	Gb4-14	Gb4-15 (336)	Gb4-16	Gb4-17
	2		2
Gb4-30		Gb4-33 (354)		Gb5-3

We have another 'feathery' sign 3 glyph lines later, 91 glyphs beyond Gb4-33:

Gb6-18	Gb7-26	Gb8-3 (445)	Gb8-6	Gb8-7

It seems reasonable to locate 'feathers' (fire) beyond the last day of illuminated moon nights (12 * 28 = 336). A fire should not be started until night has fallen.
