Some very successful experiments in blasting butts have 

 recently been carried out on the Right Hon. Lord Leigh's 

 Stoneleigh Abbey Estate, near Kenilworth. The tree butts 

 comprised elm, ash, alder, and oak, some of the latter estimated 

 (with earth attached) to weigh lo tons. 



The last two butts to be taken in hand were elm of immense 

 size. A hole i^ inch in diameter was bored with a Gilpin auger 

 into each butt, and this being charged up with Geligonite, an 

 electrical detonator was inserted and attached to the mam cable 

 of the battery. All being ready, the operator retired some 50 

 yards away behind a huge oak tree, gave the handle of the 

 battery a few turns, when the monster butt was blown mto 

 suitable pieces for loading up.-Abridged from Timber Trades

British oak for Wood-paving. 

 Though the jarrah wood of Australia continues to gain in 

 popularity as a hardwood paving for our large towns, there has 

 arisen lately a competitor to it— British-grown oak. A paving 

 block 9 by 4 by 3 is made up of six or seven small pieces of 

 oak joined together by staples, and it is claimed that these have 

 a much longer "life" than the solid blocks made from other 

 woods now on the market. -Abridged from The Timber News

Jarrah and Karri. 



In their recently issued report, the Royal Commissioners who 

 were appointed in June 1903 to inquire into the Western 

 Australian forests, estimate the extent of the virgin jarrah forest 

 north of the Blackwood river, suitable for milling, at about 

 2 000 000 acres. South of the Blackwood river there are also 

 considerable supplies of this timber, but, being so constantly 

 intergrown with karri, blackbutt, and red gum, no fair estimate 

 of the quantity can be given. 



Karri is limited to the country between the Margaret River 

 and the Porongorup river. Of this area some 150,000 acres 

 have been cut over at Karridale, Torbay, and Denmark, leavmg
