Dear Dr. Morrison: 
lour long letter of July 12 with its continuation of July 18 has 
been much enjoyed as I am always pleased to know of the details of your work. 
To take up seme of the inquiries - do not trouble to bring in the 
grinding stone that you mention. These metates are always a problem because of 
their size and weight so that the archeologists do not wish to load up on them. 
I have seen a good many but have never found one that was worn clear through. 
The other archeological material, pottery, ax head and so on will 
be valuable and we shall be pleased to have it. 
The porpoise skeleton also will be valuable. Too bad that we have 
missed out on the other anteater and on the deer® 
The cannon ball will be of interest. I note your separate 
communication regarding it which can accompany the cannon ball when it is finally 
received. Please tell the donor that we greatly appreciate this accession. 
I think I wrote you what the final decision was regarding the matter 
of alcohol. We can straighten this out later on if required. Should any question 
regarding alcohol for preserving be raised you can assure the officers that we will 
make transfer of any amount that is used whenever desired. 
Tour work on the jungle gun is well worthwhile. My experience with 
the 32 collecting pistols has been that a 15 inch barrel was the most effective for 
the type of ammunition that we use for small birds. X have tried 10", 12" and 18" 
finding that the 15” was the one that gave the best results. Whether this will work 
out with the loads that you are experimenting with still remains to be seen. 
You might find two, or even more species of the swift. As I probably 
remarked to you when we were together, most collectors do not obtain specimens in 
this group because of the difficulties attendent upon the shooting. Therefore, 
knowledge of these birds in the tropics is spotty. It is not impossible that at 
the proper season our chimney swift may pass in migration.
