452 AUSTRALIAN NATIVE PLANTS. 
EF. amygdalina, and many other fissile kinds, but not so inter- 
locked as that of /. rostrata, E. melliodora, and most of the 
species called “Box Trees.” Its specific gravity varies between 
698 and 1.108. (See below for Laslett’s and other determinations 
for comparison.) In transverse strain its strength is about equal 
to English Oak. In durability, it occupies a medium position 
amongst Eucalypts. 
The following is the number of years assigned to the sound 
wood of £. globulus:—For floors of ships, first and second 
futtocks, main and rider-keelson, beams and hook, 10 years; for 
third futtocks and top-timbers, stem and stern-posts, transomes, 
knight-heads, hawse-timbers, apron, deadwood, knees, rudder, 
windlass, timber and bilge-strakes, and ceilings between, clamps, 
stringers, shelf-pieces and lower deck-waterways, 9 years ; for light 
water-mark to wales, topsides, sheer-strakes, upper deck-waterways, 
spirkiting and plank sheers, 8 years; keel to first futtock-heads, 
thence to light watermark, 12 years. This wood is also very 
extensively used by carriage-builders* and manufacturers of 
implements ; for instance, for poles and shafts of light and heavy 
vehicles, for undercarriage work, swivel-trees, spokes and rims, 
axle beds, plough-bars, handles of axes, picks, shovels, forks, hoes, 
and hammers, and all other similar purposes. It is furthur used 
for telegraph poles, for planking of bridges and jetties, and for 
structures in water. For railway sleepers it was formerly largely 
employed, but during late years it has given way to the wood of 
E. rostrata for this purpose. Settlers used the wood of £. globulus 
for fencing, especially for rails where it is readily obtainable.

The following table taken from Rankine’s J/anual of Civil 
Engineering shows the comparative durability of some kinds of 
timber for ship-building, as estimated by the Committee of 
Lloyds :-— 
* In the report of the Victorian Carriage Board it is recommended as one of four 
colonial timbers suited for railway carriage building. It is recommended to treat it in the 
same way as “ Mountain Ash”? (see £. amygdalina), and Corner Inlet and Mirboo, Victoria, 
are recommended as suitable localities for procuring it.
