To: Dean, College of Agriculture.
From: J. Lederberg
Subject: Trip to Chicago, Frederick, Md., Gebheeda, Md., Cold Spring Harbor,L.I.,
and Lomion, Ont., dune 1951.

The primary purpose of the trip was a consultation with personnel
at Camp Detrick, Frederick, Md., on matters of interest to thea in con-
nection with our research contract. The trip was also occasioned by the
aympeaium on Genes and Mutations (largely on microorganisms) at Cold Spring
Harbor. The undersigned participated both in reading a formal paper on
“Recombination analysis of bacterial heredity", which will be published
in extaggo in the proceedings, and in many very informative private discussions
which have a direct bearing on techniques and suggested experiments here.

At Chicago, I attemled briefly at the meetings of the Society of American
BacterLologists, which gave se an opportunity to interview prospective graduate
assistant personahfor research projects next year, and to arrange with
Dra. C.P, Miller, R. Benham, E. Ordal and othera to provide nuabers of bacterial
cultures aseded in our research work.

Bethesda Mi., (Microbiological Instithte, National Institutes of Health) was
visited en route from Frederick to Cold Spring Harbor, to confer with Dr. Harry
Eagle on experiments on drug-resistance. After four hours discussion, we both
learned something. Gondon, Ont., was visited en route back to Madison to leara
something of new cytological techniques(from Dr. C.F. Robinow) to be applied in

our research, fs
