In this and the following species the branches are so elongated, thin, and 

 pendulous, as to droop in an almost vertical manner. E. macrorrhyncha F.v.M., a 

 Stringybark of inland eastern Australia; E. sideroxylon A. Cunn., an Ironbark of much 

 the same range; E. Mitchelliana Cambage, of Mount Buffalo has much the same 

 habit; E. acaciaeformis var. linearis, a so-called Peppermint of New England, has 

 also markedly drooping branches. E. coriacea sometimes has branches so pendulous 

 as to be known as Weeping Gum. . 



P.— Vertical Growth of Trees. 



This subject is touched upon in Part XLVI, p. 123, of my " Forest Flora of New 

 South Wales," based on a paper by Mr. R. H. Cambage in " The Surveyor " (the official 

 organ of the Institute of Surveyors of New South Wales) for 31st December, 1904, 

 and 28th February, 1905. 



A further paper from Mr. Cambage's pen will be found in Journ. Roy. Soc. N.S.W., 

 Hi, .377, and Eucalyptus parviflora is used illustratively. An abstract of this will be 

 found in " The Australian Forestry Journal " for November, 1919, p. 353. 



The subject is interesting to many people, because living Eucalypts are often 

 used as corner or other posts in fencing, and if as growth proceeded the rails mortised 

 into the tree were carried up and two panels of fencing injured, it is probable that 

 living trees would cease to be used for the purpose, and would be destroyed forthwith. 

 Mr. Cambage's experiments bear out the observations of people interested in fencing, 

 that the mortise-holes remain at the same height from the ground as when they were 

 made.
