Metoro recognized how with the 10th period maximum had been reached and how after that waning must come:

Eb3-32	Eb3-33	Eb3-34	Eb3-35	Eb3-36	Eb3-37	Eb3-38	Eb4-1
te maitaki	te tagata moko	te henua	te maitaki	tagata moko	te henua	Te maitaki	te henua - te kiore

Here Metoro suddenly changed to read from right to left in the type of glyph represented by Eb4-1. What should he do? How could he communicate to Bishop Jaussen that summer solstice had been reached and that sun had made a turn?

I think he managed quite good by mimicking the new turn of events in which the order must be 'upside down'.
