Information on Toxic timber from 1990

[petercharlesfagg]

This information is dated but a lot of it still applies, I thought that those interested might like to "Save-as" to their own PC's if wanted.

Some of the timber names are not as we recognise them here in the UK but a little search on-line will help.

Regards, Peter.
