From the foregoing statements itwill be seen that there 
is great diversity of opinion upon the merits of Jarrah 
timber, and time only will show whether if imported it will 
find favour with ship-builders and others in this country. 
Some three or four years since (about 1871) the 
Western Australia Timber Company were busily engaged 
in the forests preparing a large quantity of Jarrah for 
exportation. The company professes, I believe, to select 
only the best trees, and to cut them at the proper season; 
the deliveries should therefore be of the very best sort the 
country produces. I have earnestly looked for sample 
cargoes to arrive in the London Docks, but up to the 
present (1875) none of any importance have been reported.

Remarks.—E ach piece broke short. 
now much sought after for railway sleepers and telegraph posts in India and 
the colonies. It is admirably adapted for dock gates, piles, and other 
purposes, and for keel-pieces, keelsons, and other heavy timber in ship¬ 
building. Vessels of considerable burthen are built entirely of this wood, 
the peculiar properties of which render copper sheathing unnecessary, 
althoug hthe sea-worm is most abundant in these waters.”
