Oak Trees and the technology of timber conversion with particular reference to the use of water-power in West and South Yorkshire

Here follows a discussion with regard to the potential inter-relationship between the two main species of oak and the carpentry traditions of timber-frame buildings within the British Isles. It is suggested that natural distributions pre-date the development of carpentry traditions and that subsequent woodland management and the ability to convert timber using water power might have perpetuated the distribution until relatively recent times. In addition a suggestion is made that there may also be a link between cruck frames and the technology to produce appropriate sash-mounted saws and the ability to harness waterpower.
