My dear Prof. Collins 
The second part of the Flora of ITorth America has just 
been issued and Professor Underwood, Poctor Evans and I have had a meeting 
and talked over matters as a preliminary for volumes 14 & 15 which are to 
include the mosses and hectics. I am writing now to my bryological 
correspondents to know how much help we may count on and in what families of 
mosses, principally in the acrocarpus to start with. 
We have had a card card catalogue made from Engler & 
Prantl Pflanzenf ami lien including all the mouses of Greenland, ITorth America, 
Central America and the West Indies and it looms up as quite a task. 
I write to ask you whether you would he willing to 
take any part and whether your duties at Brown University would permit of 
your planning to come here fox- a month or so during the year and take work 
under one of our free scholarships. They pay §50.00 and the completed pages 
of the ITorth American Flora when printed pay $2.00 per page. Dr. Best has 
indicated his preference for the families Bartramiaceae, Uniaceae and Polytri- 
chaceae . Dr. True,I hope.will finish up his Dicranaceae and I want to do 
Fissidens , Orthotricheae and Grimmiaceae , hut would he willing to give up any 
of these to any one else who chooses to take them and tackle the Tortulaceae 
- --—— * 
which everybody seems to he a little shy of. The onlty genera that T 
positively decline to do are Bryum and Sphagnum.
