Note. — The first three columns of figures are from the Church Almanac for 1847 in which Vitex 

 littoralis was made the standard of comparison. — The last two columns are from W. W. Saunders's Cata- 

 logue, in ' Eeport of Juries/ Exhibition, 1851. 



* See, 'The Eesults of a Series of Experiments on the Strength of New Zealand and other Colonial 

 Woods ; ' by James M. Balfour, C.E. ; Appendix C, Jurors' Reports of the New Zealand Exhibition, 1865. 



p_S. — The writer of this Essay wishes to return his best thanks to those 

 few gentlemen who so kindly and promptly responded to his appeal to them. 

 He would most particularly thank His Honor the Superintendent of Auck- 

 land (Eohert Graham, Esq.) and the Chief Provincial Surveyor of that 

 province (C. Heaphy, Esq.) ; also the gentlemen composing the Chamber of 

 Commerce at Wellington. To Mr. Heaphy he is largely indebted for much 

 useful information in colonial oeconomic botany, as well as for that portion 

 of the first table containing the weight and specific gravity of woods, and 

 the whole of the last table herein given.
