He established a laboratory in the university of Arizona, at Tucson, to study tree-rings.Unfortunately, after many years of analysis he was not able to confirm the correlation he sought.He wanted to know whether the number of sunspots affected weather on Earth.
None is infallible and before embarking on an extensive dating survey, due thought must be given to what might be achieved and which methods might be the more successful. Whilst earlier types of wooden joints may be copied in later buildings and earlier styles may be reintroduced in later periods to confound the conservationist or historian, any reuse of older materials should become obvious by the use of the chronometrical methods described here.Nevertheless, the laboratory was able to demonstrate many interesting properties of ring widths and their relationship with various aspects of climate and other natural phenomena and, of course, their use in the accurate dating of timber.His laboratory is still one of the leading centres in world dendrochronology.1825 Not sure how “the younger” should be placed on the sign, but figured you would have an idea. It is a federal style house, so the 1722 is not accurate, but it has left us questioning the 1825.” My reply…” Triple center chimney with brick oven and swing arm in the current dining room, not a walk-in hearth though.The reason “the younger” is sort of important is because Nathanial Brown the Older (the father) had his house a bit farther up the road. The millwork around the front door is brand new, the house had no trim details to speak of– we think the windows are redone in late 1800s (unique push button stops), one original window remains (back attic), which is 8 over 12.
Whilst most dendrochronological research is still concerned with climatic change, where the precise dating provided by the growth rings is of vital importance, all units in this country are proficient in performing dendrochronological surveys of buildings.
