Art. XLVII. — Notes on the Growth of certain Native Trees in 



the Auckland Domain. 



By James Stewart, M.Inst.C.E. 



[Head before the Auckland Institute, 9th October, 1905.] 

 Plates XLVII-LI. 



The rate of growth and age of our native trees have often formed 

 a subject of inquiry, and observers have from time to time re- 

 corded particulars, principally relating to increase in height and 

 girth of the trees mostly used for building purposes and in the 

 industrial arts of the colony. In vol. xx of the " Transactions 

 of the New Zealand Institute " appears the last of three articles 

 by the late Mr. James Baber, who took much interest in the 

 subject, and, from his early residence in the colony, and some 

 practice in aboriculture, was well qualified to speak on it. 



In Mr. Baber's notes alluded to, written in 1887, the height 

 and girth of three kauris, planted in the Auckland Domain in 

 1865, are given, the average girth at 2 ft. from the ground being 

 2 ft. 2 in., and average height 25 ft. This represents a diameter 

 of 8£ in. only, and, as the trees had been established twenty-two 

 years, it shows an average increase of f in. in diameter and 

 about 1 ft. in height per annum, making allowance for dimen- 

 sions at the time of planting. It is to be regretted that the 

 trees so measured by Mr. Baber in 1887 were not in any way 

 fixed for future identification. It is therefore impossible to trace
