The above list speaks for itself, but I may add that taking all 
its elements together the aggregate forms nearly a complete representa¬ 
tion of the llorth American moss flora, and of course the most complete 
representation of the mosses of the southeastern United States and of 
Pennsylvania ever brought together. 
A portion of- the collection is arranged on herbarium sheets, while 
another portion is merely on the smaller cards ready to be arranged on 
herbarium sheets. The specimens as a rule, especially those of my own 
collecting, are ample. 
I value this collection on the basis of 9 / per specimen by 
actual count. Does not your institution wish to purchase it for the 
botanical department ? 
Awaiting an early and hoping for a favorable reply, I am, 
Yours truly,
