Dear Dr. Schraitt: 
Needless to say I am very much pleased and leel honored 
to be invited on this year’s Sraithsonian-Bredin expedition. 
I will try to answer some of the questions you pose in 
your letter of 30 January and ask some myself. 
1) I will elect to fly to and from Yucatan. I would guess 
the airport to be at Merida rather than Progresso. I presume 
there is some sort of bus service between the two towns? 
I would like to fly to Miami one day ahead so that I could 
talk to people at the Marine Laboratory regarding what I might 
expect to find among the fishes along the Yucatan coast. How 
should arrangements be handled? Will you arrange a flight schedule 
or should I? Will it originate here at VJilmington or at Washington 
2) I have foior cases I use on collecting trips that measure 
13i X 20g X 17 inches. I will try to confine my gear to these 
four plus personal effects. I will ship these to you by 1 Narch. 
3) I will bring a nylon seine 25 - 50 feet long but without 
brailles. I haven’t decided what other collecting gear to bring 
along but it will be concerned with fish, and any existing marshes. 
Will inform you later. 
4) My personal camera is a Hasselblad which uses 120 film. 
I would suggest the following color film Kodak Ektachrorae 120 
daylight E 3 with a film speed of ASA 50. For black and white 
pictures Kodak Plus X Pan 12U. Both kinds produce 12 pictures 
2 ^ X 2^ inches per roll with my camera. 
5) I will attempt to keep a log of daily activities. 
6) I have already initiated action pertaining to a passport 
and approppiate shots. According to Darsie, I should start pre- 
ventive malarial procedures two weeks before leaving. This I will 
do unless I hear to the contrary from you.
