Nature Climate Change 2:172-176. NOTES: BLHS ('Black House', 22 Wynyard Street, Auckland) was a California- style bungalow constructed ca. 1912/13 (certainly by 1917) and demolished 2003. Twenty-eight samples collected from framing and cladding timber. Two series crossdated. Raw ring width only (0.01mm). No chronology as these series are probably same tree. Please note that because of the large size of kauri and industrialized production (a) the series represent only part of the growth span of the tree; (b) same tree series may occur in the assemblage.
