- a raised road
- a study of traffic on raised roads
It should be noted that my conception of watch-towers had not yet been fully developed. Here one is represented as a simple rectangular structure. The brazier producing smoke as a form of sending signals was later superseded by a heliograph.
The second diagram is a result of a study I did into the density of traffic on one of the ‘spoke’ roads leading to Osrakum. This is typical of some of the excesses that I got into when writing The Chosen. I wanted to know what the road might look like from a leftway. There is a subtle inference that can be drawn from the diagram that should become clear on completion of the Stone Dance.
