'Ey dear Ers. Horr:- 
Thank you very much for 
your letter and offer to send me specimens 
of the "Hair-caps". If it will not he rob- 
bonp you I would like to get a hit of each, 
a few stems merely for locality of each. 
I am ; arti cularly interested in the penera 
Catharinaea, "oponatum, and rolyttichpm, 
as you will see from one of the . amphlets I 
am sendinp you at this time. I would espec¬ 
ially like to pet olytrichums prowin y in 
different kinds of habitats, as you will see. 
You say you are not familiar with olyt- 
richum gracile. I have write a number of 
specimens of a mountain form collected in 
Gaspe a few years apo. If I can ever pot 
at them I will try and remember that yoiz want 
a specimen. If you do not pet a specimen 
from me within two ninths please jog my mem¬ 
ory. Hy time for m'ss work is very irregular 
and, at most, rather limited, so there is no 
certainty when I can pet at the work that I 
best like. Unfortunately it is ofton the 
case, an in this instance, that our preferred 
work does not bring bread .nd butter. 
Very truly yours,
