Dear Chamberlain:- 
I certainly had ideal weather for the Penn, 
trip. Three days I was working: with my sleeves foiled up 
above the elbows,and two days i had my hat off most of the time 
and was perfectly comfortable all the time. Easter afternoon 
I pecked quite a bunch of Arbutus to bring- home, part of it 
was in full bloom, btt most of it was only well dlong in bud, 
I returned via the Str. ’'ayyland route form Jersey City to 
Harlem. , 
Am sorry to hear that-you have mot to change your plans 
for the summer. Where do the people go who want you to join 
them? 
I do not know where you can get a dopy of Parlow's paper 
on nomenclature Perhaps Dr. Robinson might be able to tell 
you, I had quite a tlk with Farlow within a week of the time 
that he sailed. Am glad to say that he in a strong advocate 
of the same date that I am for the starting point for the 
mosses (Hedwig, 18Gl1 
Let me know when you decide about your summer. If you are 
about Hew England perhaps we can get in a few days together 
in early September. 
Cordially,
