108 REPORT OP EiLLWOOD C. PERISHO, STATE GEOLOGIST 



Early in 1913, work was started on the mounting and labelling 

 of the large collection of the type botanical specimens of our state, 

 mostly collected by S. S. Visher under the direction of the Survey. 

 This was accomplished and a metallic case was purchased and 

 placed in the Museum to contain the plant collections. This gives 

 the state an exceptionally valuable herbarium so arranged that it 

 may be used as a work of reference by all who are interested in 

 botany or the plants of the state. The collection is especially rich 

 in the flora of the Black Hills, Forest Reserves, western plains 

 and many other localities of the state. We yet need to make 

 extensive collections of the early spring flowers in a number of 

 counties before the herbarium reaches its maximum of completion 

 and usefulness. 



Another valuable addition to the Museum in the spring of 

 1913 is a large case of old Indian stone, flint and bone articles, of 

 2,000 specimens, about 500 of which belong to the department and 

 represent the implements of warfare, the chase, and ornamentation 

 of the Arickaree Indians, who formerly lived on the Missouri 

 River in South Dakota. The balance of the collection was loaned 

 by William HI Over. It is valuable on account of representing 

 the implements of prehistoric races of America, and is the largest 

 and best collection of old flint and stone relics in South Dakota. 



A large case of land and freshwater Mollusks were also loaned 

 by William H. Over and displayed to the public. There are nearly 

 1,000 species of shells in the collection, properly identified and 

 labelled, representing the Mollusca from all parts of the world. 

 One hundred and thirty species of Unionidae or clams of our 

 rivers and lakes are shown in this case. In the display there is 

 also a series showing the economic products of the clam shell as 

 manufactured at the pearl button factories along the Mississippi 

 river. 



A collection of one hundred twenty-five species of woods were 

 received from the Philippines and properly displayed. 



In addition to a number of skins, forty-five mounted birds and 

 seven mounted mammals including a black bear and a coyote 

 have been added to the Museum during the year 1913. The taxi- 

 dermy work was done by H. E. Lee of Rapid City and William 

 H. Over. Many valuable specimens were presented by friends to 

 the Museum during the year. Every one was properly labelled
