Letter from Charles R. Burnham to Barbara McClintock
Burnham indicates that he has read Evelyn Fox Keller's biography of McClintock and that it has caused him to reevaluate his relationship with McClintock. He briefly discusses his health and his observations of some recent work on maize genetics.

Dear Barb,
This is in response to the very interesting book by Evelyn Fox Keller "A Feeling for the Organic." It is an excellent presentation of you and your work. It filled in some gaps for me, and has made me think about the many interactions we have had over the years: at Cornell in 1929 and 1930; then at Cal Tech, at Missouri, back at Cornell, then much later at Cornell when I gave a talk there, your visit here at Minnesota, at the Illinois Symposium, the Stadler lectures at Mo., and last July at Ithaca.
All of them are very warm memories, your interest, support, and (I believe) your belief in me are appreciated. There should have been a greater response on my part; but, better late than never? I wish we had had more time to talk at Ithaca. It would be nice to get together for some reminiscing and looking at the future.
Enclosed is a copy of what I wrote for Bill Sheridan's Book on Maize -- my recollections of events at Cornell and the work on corn and barley. They are as I recall them and the course of events. Some of the more personal aspects were omitted.

As for my health: checkups have shown that the hormone (female) has not resulted in the harmful side effects that sometimes occur (lower hemoglobin); and the prostate cancer has not progressed -- as the Dr. says, it has been checked but not cured. I do have to walk slowly, but field work, planting, etc. involves enough stopping that there is no problem, other than the need for frequent rests.
You probably saw the report by Helmy Ghobrial in the Corn News letter. He has treated more F1's, some with 2[scientific formula], some with a [scientific formula]20. The intention is to examine the plants more closely, from the 5th and 6th leaves on to maturity, not waiting for the pollen shedding stage. If the entire growing point is changed (since tiller and tassel, all branches did shed pollen of each), if it is polyploidy, number of stomata per sq. unit, should be changed. Why are there both n-sized and 2n-sized pollen not only in the plants that shed pollen but also in the progeny from them that are partially sterile and shedding pollen? When the results on progeny from selfing, and on the test crosses of the fertile plants from selfing are in; a better understanding of what colchicine treatment does should be forthcoming.
Progress continues on the chestnut work: more pollen from Chinese crossed with American F1 hybrids from Shafer but also from a first backcross to American chestnut that is flowering at Coan. (Richard Joynes). A review paper of the work, past, present, and future has been completed. Now the question is where it can be published? A short version[?] may be the answer.
