other trees of nearly the same age (in which case the rate of growth in 

 diameter was usually slower, although the height of the tree was probably 

 greater). In short, any facts that appeared to be serviceable in the con- 

 sideration of the question were noted and tabulated. 



The total number of trees included in the following table is twenty- 

 nine. Of these Nos. 1 to 7 are cultivated trees, the date of planting of 

 which is accurately known. The number of annual rings given for these 

 specimens is the number of years since they Avere planted, plus three, 

 the estimated age when planted. The rings have been actually counted 

 in a sector of the stem in the remaining twenty-two ; and with the ex- 

 ception of No. 9, which is taken from Mr. Laslett's book, "Timber and 

 Timber-tree. " (p. 45), and the last four (Nos. 26 to 29), for which I 

 am indebted to the kindness of Mr. W. A. Nisbet, the countings have 

 been taken by myself. I have, however, to thank my friends Mr. J. 

 Stewart, Mr. T. Herbert, and Mr. C. Spencer for kind assistance with 

 several sections.
