Important contributions to our knowledge were made by 

 G. A. Waller, who was Assistant Government Geologist from 

 1901 to 1904, In addition to his valuable descriptions of 

 many of our ore. deposits and his pioneer work on their 

 genesis, this enthusiastic worker did m.uch to advance our 

 knowledge of the stratigraphy of the Lower Palasozoics on 

 the West Coast, as well as succeeding in throwing much light 

 on the petrology of the associated igneous rocks. 



L. Keith Ward, B.A., B.E., during the time he occupied 

 the position of Assistant Government Geologist from 1907 

 to 1911, was responsible for very great progress in geological 

 research in Tasmania. Immediately after his appointment 

 to the Survey there was instituted the present series of Geo- 

 logical Survey publications which is in accordance with the 

 system in vogue in modern Geological Surveys. His ov/n con- 

 tributions to this series of publications set a very high 

 standard both as regards literary merit and method of treat- 

 ment. The thoroughness of his investigations and the illu- 

 minating conclusions he drew therefrom have great value 

 both from the importance of the acquired information itself 

 and from the fact that his conclusions and hypotheses supply 

 an invaluable method of approach to many of our petrologic 

 and metallogenic problems. 



The work performed by L. L. Waterhouse, B.E., Assist- 

 ant Government Geologist from 1912 to 1916, has also added 

 to our knowledge. The detailed descriptions contained in 

 the two bulletins prepared by him supply a wealth of in- 

 formation concerning the two areas with which they deal. 

 To this investigator there is undoubtedly due the credit of 

 throwing much light on the detailed petrography of our De- 

 vonian granites, and their contact metamorphic deposits, as 

 well as considerable information concerning the factors con- 

 trolling tin deposition in Tasmania. 



To this enumeration of former officers of the Geological 

 Survey of Tasmania, who have materially advanced our 

 knowledge, mention must be made of the present officers of 

 that organisation who are at work on important geological 

 problems. The writer joined the Department in 1912, on the 

 occasion of an increase in the staff of the Survey. Mr. A. 

 Mcintosh Reid joined the Geological Survey in 1917, and, 

 together with Messrs. P. B. Nye, B.M.E., and H. G. W. Keid, 

 B.Sc, who were appointed early in 1920, are actively engaged 

 in conducting geological surveys according to the programme 

 authorised by the Honourable the Minister for Mines for 

 Tasmania.
