INTRODUCTORY. 



Stone implements of various forms which have been collected 

 from the present Indian tribes of Wyoming and neighboring States 

 are rather familiar objects in museum collections. These implements 

 comprise the well 'known maul or hammer used in crushing berries 

 and meat, arrow planes, and the simple flakes and rudely chipped 

 implements used in the dressing of hides. In addition are a number 

 of other stone objects, nearly all of which are used for various 

 domestic purposes. Among them are occasionally arrow or spear 

 points of flint, but as a rule objects of flint are not encountered 

 among these collections. That the Indians of Wyoming used count- 

 less numbers of arrow and some spear points of flint there is no 

 doubt, but I am not aware that large flint knives or flint agricultural 

 implements have ever been collected among or found in use by these 

 Indians. Hence the added interest attaching itself to a quarry where 

 the rejectage indicates that the manufactured objects sought after 

 were large knives, and, above all, agricultural implements.
