 Stephen S. Visher, under the following subjects:

 2nd. Biennial Report of State Geologist. 



The Survey has much material, including field notes, manu- 

 scripts, etc., which should be published as soon as funds are avail- 

 able. 



The above will include material for two bulletins ; one on the 

 Geology and Mineral resources of Northwest South Dakota. The 

 other, The Birds of South Dakota. 



V. WORK TO BE DONE. There are a number of in- 

 vestigations that the Survey should do for the people of our 

 state. Among these may be mentioned : 



i. The continuation of the collecting and proper mounting of 

 the type fauna and flora. The longer this work is delayed the 

 more difficult it will be to procure the needed specimens. A sum 

 expended now, in the biological work of the Survey, will accom- 

 plish much more than even a large appropriation can do in a few 

 years hence. 



It is the wish of the Survey, not only to locate and discuss and 

 put to the service of the people the economic products of the 

 state, but also to form a good working museum, where there will 

 be found, in usable condition, the type fauna and flora of South 

 Dakota. We are certain that everyone, especially teachers aftd 

 students, will be interested in seeing a large and complete collec-
