Caterways was used occasionally by my mother, born and bred in Sussex - it is possible that the caterwise spelling is a phonetic representation of the accent - its hard for me to remember the true strong Sussex now, which her parents used but she did not, but I think the actual pronounciation was not a pure ay or a pure eye sound. My mother used it to describe the way footpaths crossed fields corner to corner. I use it even more occasionally, and in full knowledge that I am being arch, or something artificial.
