Dear Mr, Zinser j 
Unless some tiling unexpected arises to prevent I hope 
to make a short collecting trip in southern ?era Cruz early 
this coming spring, I expeot to leave Washington during 
the latter part of February* and to be in the field during 
March and the early part of April, We have a party doing 
archeological work at Tree Zapotes inland from Tlaootalpen 
where I will make the base for my work. 
It will be much appreciated if you oan see your my 
clear to grant the necessary collecting permit for the taking 
of birds for scientific purposes so that I may carry out this 
work. If practicable I should like to ask that the permit 
be made unlimited rather than restricted to three individuals 
of eaoh species, I oan give you my assurance that there will 
be no abuse of this privilege, and that all speoiirons obtained 
will oome to the United States National Museum. For our work 
we need, in some oases, a few more specimens than the average. 
Your cooperation in this matter will be much appreciated, I 
am ©nolosing herewith two signed photographs for use on the 
permits* 
In my collecting outfit I shall have two 16 gauge 
shotguns, and the usual supply of ammunition for the oolleotion 
of birds. These will inolude a considerable number of 32 
caliber shells loaded with very fine shot (No, 12) which fit 
in an auxiliary barrel for use in these shotguns. A short time 
ago I asked our State Department to take up with -the proper 
officials in Mexico City the question of Importation of these 
guns and ammunition, and have hod reply that this would be done 
Immediately, I plan to oome in by way of Laredo,
