Speculation that wood gradually loses its ability to absorb and desorb water is shown to be without foundation. twelve specimens of wood of different species and of age varying up to three thousand seven hundred years were tested. There appears to be a very slight decrease in hygroscopicity with age but more specimens would need to be tested to confirm this trend. In any case, there is no doubt that wood retains its reactivity to moisture however old it is.
