Arbutus Uvaursi ZL. (Kinn-kinmk.) Smoked by the 
Indians asa substitute for tobacco. The Arbutus is seldom 
used by itself, though it forms the principal ingredient in 
the composition called Kinni-Kinnik. The bark of Co- 
mus sericea, and of several other plants are generally mixed 
with it, though a little tobacco is preferred. ~Pursh says the 
Indians of the Missouri call it Sacacommis.

New-England and in the northern parts of the state of New- 
York, growing in sphagnous swamps, and on the borders of 
mountain lakes.
