Gardens, Melbourne, it took twenty-five years to grow 

 12 feet, while the length of its leaves was only 3 inches. 

 At Corrie Hotel, Arran, 35 yards from the sea, in eleven 

 years it was 14 feet in height (2 feet when planted), while 

 one of the leaves measured 9 inches x 5 inches, and 

 weighed f of an ounce. See also below as to leaves of 

 E. globulus. This conforms with the fact that Sequoia 

 gigantea grows much more rapidly in some places in 

 Britain than on its native mountains of California. E. 

 alpina will be tried in the south of Arran.

The Blue Gum from its rapid growth, great size, the 

 excellence of its timber, the large amount of ozone gene- 

 rated by its leaves, the antiseptic power of its volatile oil, 

 and the great amount of moisture absorbed by its roots 

 fitting it for drying swamps, is one of the most important 

 of the trees of the world. (See also note under E. rcgnans, 

 p. 522). The following note regarding the growth of the 

 Lamlash Gum is given by James Paterson, Esq., at the
