corresponding subalpine flora. Large masses of snow, numerous lakes 

 of clear water, but without fish, and extensive marshes were every- 

 where met with along the march. In exposed situations, between 9,000 

 and 10,000 feet, scrubby specimens of Picea Engelmanni were found, only 

 a few feet high, twisted and contorted out of shape and lying nearly flat 

 on the ground above where there was no timber; Pin us Balfour iana was 

 not found.

The beautiful Gent inner frigida was quite ornamental on the high 

 plateaus and mountain sides, where the snow had recently melted. As 

 a rule the flora of this high grauite region is comparatively meager, 

 owing to the fact that much of the surface is covered with rock ; but 

 the subalpine grasses are well represented by numerous species. 



The following is a list of the botanical specimens collected, which have 

 been arranged and classified according to their natural orders, and de- 

 posited in the herbarium of Harvard University, Cambridge, Mass. I 

 am greatly indebted to Prof. Asa Gray and Mr. Sereno Watson, of Har- 

 vard, and to Dr. George Engelraann, of Saint Louis, for determinations 

 of the species and other courtesies, and to these eminent scientists my 

 thanks are tendered.
