GRAY HERBARIUM. 
AN EXCURSION TO MT. WASHINGTON, MASSACHUSETTS, 
AND BASH-BISH FALLS. 
CLARENCE H. KNowrrow. 
Wuen the New England Botanical Club made its 1919 spring 
excursion to southern Berkshire County, Mr. Charles Schweinfurth 
and I received as our first day's assignment the southwestern corner 
of the County and State, the township of Mt. Washington, especially 
the region of Hudson River drainage. We found about 200 species

several brooks, which join Bash-Bish brook and flow westward into

Vermont. 'The country rock is mica-schist, although casual plants 
of Cystopteris bulbifera, Ranunculus allegheniensis, Viola rostrata and

drift.
