American field. There la one other point, not so important, 
perhaps, and that ia my rule to open the pages of Orohidaoeae 
only to authors who wars: in oo-oparation with me* While at 
first I was inclined to treat ay serial as an open avenue to 
authors who had critical work on orchids to place before the 
world, I soon arrived at the conclusion that with five vol¬ 
umes behind me it would be wall to keep on as I had been go¬ 
ing and to make Orohidaoeae a one-ipan Job. Some day ?.oa may 
wish to have a critical revision of the orchids of Panama 
placed before the orohidologlsts with illustrations of the 
apeaios. It would be a pleasure to co-operate with you for 
this purpose and to give you a place,as Field Aiithor., in a 
volume of Orohidaoeae. You would enjoy this work because it 
would call for critical field studies, intensive herbarium 
work in the great museums of the world, acid make possible the 
illustration of the complete orchid flora of Panama up to the 
time of going to press* My work for hr* Standley has given 
me a pretty fair start toward keen familiarity with the flora 
from northern Mexico into northern Colombia, so that I am 
in a position to eo-oper&ta with you to the fullest extant . 
When I meet hr* Sohleohter I will put the matter of pub¬ 
lication before him and you may rest assured that it will os 
a pleasure to further your interests to the full limit oj. my 
ability and influence*
