ERRATA. 



Page 119, fourth line from bottom, read bluebird for blubird. 



Page 121, fifteenth line from top, read alpina for montana. 



Page 149, twentieth line from top, read Betula papyrifera for Betula 

 papyfera. 



Page 163, twenty-first line from top, read Blackfeet for Blackfoot. 



Page 122, second line from top, read Lace lake for Leash lake. 



Page 147, ninth line from top, read ponderosa for scopulorum. At 

 other places where reference is made to yellow pine ponderosa should be 

 used instead of scopulorum. 



Page 147, fourth paragraph from top, Populus angustifolia should 

 read Populus balsamifera var. candicans. Dr. J. W. Blankinship of the 

 Agricultural College expresses the opinion that this latter is the only 

 species in the western part of the state.
