 Director of the Geological Survey of Tasmania, and con- 

 tinued his work practically to the time of his death. 



During his regime, the work in his branch of the 

 Department grew in volume and importance. The Geologi- 

 cal Gallery, at Launceston, established in connection with 

 the Geological Survey, will always stand as a me- 

 morial to his enthusiastic work. 



His connection with variotis scientific societies is well 

 known, and his many valuable contributions in the shape 

 of scientifie writings will ever serve to remind geologists 

 and others of his work. 



Owing to his death the State has lost a valuable 

 servant, this Society a prominent member, and many of 

 the remaining members have lost a personal friend. Mr. 

 Twelvetrees's kindly nature led him to be honoured and 

 respiected by all classes of people, and his loss will be felt 

 far beyond the realm of the scientific world.
