As much as I do my best to adhere to the various rules that I have established for myself in this project, there are always elements of failure. Sometimes it is because the specific rule only occurs to me in the midst of things. For instance, I decided after the second walk to keep all of my used grinding blades. I had already, however, discarded the first blade, so in the end I was left with just six. I could, of course, have just ground another blade until it looked suitably worn, providing me with an apparently scrupulous full set, but this would infringe an even more important rule, that I cannot cheat any of my procedures. It is not just that I am averse to cheating, but that the work depends precisely on attending closely to whatever it is that actually occurs (or seems to occur). Abandon this principle and the whole work collapses.
