r, and Niblack
varieties, whereas Butterick, Indiana, and Posey were protogynous. He
did not specify in which class the Greenriver fell. Major during each of
the four years, had an interval of 1 to 3 days between the last shedding
of pollen and the first pistil receptivity; Warrick, an obsolete
variety, had some overlap each year as did Indiana and Posey. The
Kentucky, a discarded variety, had overlaps the three years it was
observed. In two years it was observed, Niblack had staminate and
pistillate flowering together one season, and staminate overlapping four
days into the period of pistillate receptivity the next. Busseron,
Butterick, and Greenriver sometimes had overlaps and sometimes
intervals. Reed's conclusion, that "northern varieties of pecan ...
appear to be partly or completely dependent upon other varieties for
pollen," still holds good, as does his second observation, that "all
varieties tend to vary, from year to year with respect to periods of
pollen shedding and pistil receptivity." But more records are needed,
and any members who have two or more varieties flowering in 1952 can
make valuable contributions by taking accurate notes on their
habits. There are now newer varieties for which such data are
completely lacking, and until more is known, no reliable basis can
be had for matching them with the best combinations for adequate
cross-pollination.--J. C. McD.]

[Footnote 7: I think the first phase of the suggested experiment has
more to recommend it than the second. Perhaps the Round Hill tree gets
needed zinc from clotheslines and roofing nails. A more scientific way
to apply zinc is to use zinc sulfate in sprays or ground applications,
and these are to be used on some trees at Urbana which Dr. Crane
diagnosed as zinc-deficient.--J. C. McD.]

[Footnote 8: The Bradley Brothers, who do not court anonymity, are no
fellows of the Association or of the University of Illinois. They have
been known to sell some kind of grafted pecan trees in recent years,
possibly the Stuart or some other variety available from southern
wholesale propagators. Mr. Taylor was lucky enough to have his order
filled with a southern Illinois seedling which at least is good for the
squirrels. We haven't yet seen any All State nuts from Maine or Montana.
The Bradley variety is an obsolete southern pecan.--J. C. McD.]
