The idea of structuring the book around the seasons has suggested to me the possibility of using the year as a model for the book. 2012 is a leap year, consisting of 366 days; since the majority of the work takes place in this year, It would make for a book of that many pages, plus a number of extra pages at the beginning (pre-numbering) for contents and so forth; say 7, if we're going for calendar correspondences.
The book shall therefore be divided into four sections. I'll work based on the periods between solstices and equinoxes:
Spring: 21st March - June 20th: 91 days
Summer: June 21st - 20th September: 91 days.
Autumn: 21st September-20th December: 90 days.
Winter: 21st December-20th March (Including 29th Feb): 90 days.
I have been trying to set the structure out in various text files and in indesign, but I think I'll have to make a physical model of the book in order to be able to get a real sense of how this all pans out, whether this is a good idea and whether any fudging will be necessary
I will also need to pick up the pace a little on the first section, though I have photographs, sound recordings and notes on all three of the first walks; the season draws to a close. One of the interesting things about the actual making of Vectis is that, due to the writing and other considerations, the first section shall probably take the longest to produce in terms of post-production, though I already have almost all the material I need on hand. I shall be walking all three routes again in the next few days, before moving out. Already autumn's chill is in the air. The 21st is the first day of autumn, and will be time to begin considering the longer range walks.
