By Mr. Walter Hill, Director Botanic Garden, Brisbane, Australia. Mr. Hill not only gives here a list of the timbers exhibited at Philadelphia, Paris and elsewhere, but describes in detail their uses in the arts, thus making the paper one of permanent value. By this list it seems there are 229 timber trees in Australia. Already there, as here, some very useful kinds are fast disappearing, and laws have to be made to protect them. In this list appears the Australian red cedar, Cedrela Toma, which seems very valuable.
