Wane is significant as this was the last annual growth ring to be deposited, so to speak, before the tree was felled.

If, by using the method of dendro-dating, it can be determined when the outermost ring was formed the possibility exists that the construction date of a timbered building might be determined.

The oak slice from the Taylor stone Lancashire style ground barn located just west of West Chester in Chester County, Pennsylvania was dendro-dated to 1752.

This date established the structure to be the earliest basically intact and scientifically verified barn in all of Pennsylvania.

Scientists and scholars of various disciplines have been using recent advances in dendrochronology, or tree-ring dating studies, in the Northeast along with the development of regional master chronologies for various species of trees to promote the dating of timber framed buildings and other buildings that have timbers somewhere in their construction.

However, the home owner is becoming more and more interested in knowing the exact dates of construction of both their houses and their barns.

The oak slice from the Tredyffrin double log crib English Lake District style bank barn located near Devon in Chester County, Pennsylvania was dendro-dated to 1779.

This barn type is an extreme rarity in Pennsylvania.
