ckberries around, it will be quite a problem to control the stink
bugs.

DR. MCKAY: Now I am going to take up the problems that have been sent in
by mail. The one dealing with early vegetating and frost damage to
Persian walnuts was sent in by the most people.

Mr. Snyder lives in a fairly cold country. I am going to ask him to give
us his ideas on this problem and what might be done with it.

MR. SNYDER: I am not qualified to discuss that problem, because we can't
do anything much with Carpathian walnuts. We do have some grafted this
year, and we will have one, in particular, Carpathian, No. 5--I don't
know where it got that number--Crath No. 5, I believe it is, on a young
grafted black walnut tree which is ripening up almost ahead of the black
walnut, and both have made a remarkable growth. But so far as the spring
is concerned, I don't know how they will come out.

DR. MCKAY: Mr. Bernath, what are your views? You live in a fairly cold
area. You propagate Persian walnuts. What is your opinion of this
problem?

MR. BERNATH: Well, there is a way to help that situation. After the
ground freezes, keep that ground frozen. That will delay the growth of
that tree, if you have the time and patience to keep the ground frozen.

MR. SNYDER: I don't believe it.

MR. BERNATH: Yes, it will.

DR. MCKAY: It seems to me we have a difference of opinion here between
Mr. Snyder and Mr. Bernath. The question is this: During a warm spell in
the spring will a tree with frozen roots grow up here in the air. That's
the question.

(There was a chorus of "yes"es from the audience).

MR. STOKE: I would say that one good solution is to select late
vegetating varieties. Mr. Oakes in a report to me on the blooming habits
of Persian walnuts, stated that the variety Schaeffer did not start
growth until the 29th of April. That is almost four weeks later than
most other varieties. And I know from the tabulations that I have made
that some varieties are weeks ahead of others. So let's select the late
varieties that are good and worthwhile and plant those.

In my section our latest spring frost averages the 20th of April, and
yet I have several varieties that do not bloom until after the first of
May. That's the ideal condition.

DR. MCKAY: That's true, Mr. Stoke, but here is another point to
consider. Persian walnuts have a short cold requirement, you know that.
Hence, in February or early March or any time, even in January, when we
have
