and to ascertain whether any of them are comparable with the 

 Australian Mallees. 



AVe are greatl}' indebted to our correspondents at a distance, 

 for their kindness and trouble in sending us such material as 

 they were able to get. But we are specially indebted to Mr. 

 Cambage, not only for material, but for his valuable help in 

 identifying a number of our seedlings, and in other ways. We 

 have also to thank Principal Potts for the opportunity of getting 

 samples of seedlings of four species ivom seed-beds at the Hawkes- 

 bury College which have been of great use to us: and to Mr. A. 

 A. Lawson for help in completing our series of photographs.
