504 TRANSACTIONS AND rROCEEDINGS OF THE [Sess. lvii. 



Mr. Edwin Lees gives a drawing of a monstrous hollow 

 alder near Strawley, AYorcester, 45 feet in girth at the 

 base, the neck being 2 feet up, where from the drawing it 

 must be 30 feet at least (Journal of Forestry, vi., p. 4). 

 May this not be more than one tree ? 



Rate of girth-increase at 5 feet of an alder, Edinburgli 

 Arboretum (D. Christison). 



XV. The Australian Gum Tree {Eucalyptus). 



Several species planted in the Isle of Arran by the Rev. 

 D. Landsborough, Kilmarnock (information furnished by 

 him). Girths at 5 feet up. In calculating the rates I 

 have made allowance where necessary for growth to 5 feet. 

 All the trees were sown or planted, and the measurements 

 taken, in spring.
