Bogota, Colombia. 
Dear Dr. Dugand: 
I have been delighted to have yours of February 8, and 
am looking forward to meeting you in Bogota next month. As stated 
in ny letter of January 27 I expect to reach Barranquilla on the 
United Fruit Line Steamer "Quirigua" March 10, and will come to 
Bogota by air as soon as I can make the necessary arrangement. 
Mr. Carriker will go to Santa Marta to make preliminary arrange¬ 
ments for our trip and will wait for me there. I expect to spend 
about a week in Bogota. 
Mr. Carriker and I plan to get a camion in Santa Marta and 
to travel with this through Gasare and Valle Dupar to Riohacha and 
then cross Into the Goagira. We expect to stop briefly, perhaps 
for a week, on the way but will plan on working first in the Goagira. 
I believe we can use the camion through the western half of the 
Goagira but will expect to get horses to cover the eastern section 
which is the most interesting* I shall have to return as I told 
you about the end of April when Mr. Carriker will finish in the 
Goagira if we are not already through, and will then come over into 
the Perija and Motilone section. I am sorry indeed that I shall not 
be able to remain for the entire period. 
I shall be pleased to have Mr. Carlos Lehmann accompany us 
for three or four weeks as you suggest and trust that you will be 
able to make the necessary arrangements. As I have indicated above 
I expect to return from Bogota to the coast by air. I am not 
certain at the present moment as to the length of time required for 
transportation overland. Mr. Lehmann may wish to ship his equipment 
or to travel himself Ahead so that he can meet us in Santa Marta, 
or he can arrange to meet us in Riohacha. I am told that there are 
small boats that run along the coast between Santa Marta and Riohacha 
I shall be interested to meet Mr. Lehmann as we have had some 
correspondence,principally about hawks. I am also happy to learn 
that you are building up a collection in ornithology as this will be 
an important part of your work and one in which there is much to be 
done.
