If research into other sources of information also fails to throw light on the building's history, resort may be made to the various scientific methods of dating.

Any possible effects of storage and/or transportation time on the susceptibility of the timber to bacterial degradation are considered.A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.Each ring marks a complete cycle of seasons, or one year, in the tree's life.In his Trattato della Pittura (Treatise on Painting), Leonardo da Vinci was the first person to mention that trees form rings annually and that their thickness is determined by the conditions under which they grew. S., Alexander Catlin Twining (1801–1884) suggested in 1833 that patterns among tree rings could be used to synchronize the dendrochronologies of various trees and thereby to reconstruct past climates across entire regions.During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.
