Dr. Alexander Wetmore, 
c/o Consul-General of the United States, 
Calle Lavalle 341, 
Buenos Aires, Argentina. 
Dear Dr. Wetmore: 
Your letter of January 21 is just received, and I am 
glad to learn that you plan to continue the work at least until 
April, and that you may he able to get into northern Patagonia 
again for a brief period before crossing into Chile for observa¬ 
tions on the migration referred to along the coast in that region. 
I understand, of course, that it is impossible to work out 
more than a tentative itinerary, and have had the same experience 
as yourself in regard to localities worked, that is, certain ones 
highly recommended frequently prove to be very poor, and very profit¬ 
able ones are met with unexpectedly. I trust that no general strike 
will tie up the railroads and incidentally your operations in Argentina. 
The identification card referred to had already been sent you 
when your letter was written, and has doubtless reached you long before 
this time. 
I am glad to have the information concerning Dr. Von Ihering 
and his present activities, and hope you will have an opportunity to 
meet Mr. D. S. Bullock of the Bureau of Markets, who left for South 
America some time ago. It would be interesting to arrange to keep in 
touch in a general way with the results of the expedition which you 
write the Museo Nacional of Buenos Aires has just dispatched to Tierra 
del Fuego. It is needless to say that the material secured by the 
expedition will be of the greatest interest. 
I am glad to know that you were able to make more satisfactory 
arrangements for handling your second and third shipments. You will 
be advised of the arrival of your third shipment, which I judge from 
your letter should be very soon. 
Sincerely yours.
