Dear Dr. Clark: 
With the New Year approaching rapidly Panama 
is uppermost in my mind as usual at this season. I hope 
now to get away from here soon after the first of February 
and to be in Balboa. 
When you were here I told you something of my 
plans and you were kind enough to say that you though it 
might be possible to release Ratibor Hartman to me for the 
six or seven weeks necessary for the field work back of 
Chiman. I would expect to pay him the same salary that 
he would receive from you and his expenses. He would also 
have full opportunity to collect the insect material in which 
Major Hertig is interested. In fact, I believe that this might 
be a valuable addition to the material with which Maj. Hertig 
is employed. 
I will appreciate hearing from you as to whether I 
am free now to write to Ratibor relative to these plans as I 
want to take up a few details with him as early as possible 
in January. We have our Annual Meeting of the Board of 
Regents on January 13 and the Congressional Hearings about 
the same time. I am going to get away as soon after these 
tasks are finished aef'I can, and wish to have everything in 
order. 
1 was surprised at my election to your Board and 
learn from Colonel Siler that I am also ont he,Executive 
Committee I have recently received a set of annual reports
