you receive this material I would welcome your opinion of it. 
In January a friend of mine is to start on a collecting 
trip through Colombia. I have offered to pay the expenses of 
a botanical collector who will accompany him and gather mater¬ 
ial for me of orchids and economic species. If this plan comes 
to anything I will send you a set of duplicates. I have other 
co-operative schemes in mind and you may depend on me to share 
with you if I receive material in duplicate. 
By this time the sixth volume of Orehidaceae must have 
reached you. I hope you will fine the work helpful and worthy 
of praise. I have set aside for you the first set of duplicates 
of the Clemens and Has&am specimens. There must be nearly two 
hundred specimens in the set. I also have a set of the plates 
ready to send off to you. These will oe of interest for"your 
herbarium. 
I understand that Rolfs is about ready to retire from the 
Kev- staff. About a year ago he wrote to me about this and sug¬ 
gested that we might co-operate in some way with regard to 
orchid work. I have not heard from him since. But I expect he 
will keep me informed of his plans. 
Yours very truly.
