at
a disadvantage in transplanting conifers. Regarding the comments as to
paraffin wax melting, I do have a little difficulty on the south side
and sloping to the northeast. The sun's rays would be rather direct. I
think the suggestion Mr. Weber made was very good. Two-thirds paraffin
and one-third beeswax. Possibly we would have to increase the beeswax
where trees are growing on a southern slope.

DR. ZIMMERMAN: I found the hottest place 2 inches above the
soil. I shade grafts with a piece of shingle.

THE PRESIDENT: The principle in grafting trees is to regulate
the moisture and the temperature factors. As a means of regulating the
moisture I use German peat around the graft.

MR. HERSHEY: Have any of you had experience in grafting on the
north side of the stock? I found that quite a good scheme, so that the
heat doesn't kill the grafts. We grafted on the 15th of June this year.

THE PRESIDENT: Professor Drake has done a good deal of work in
locating good varieties of black walnuts in the southwest and I am sure
he will be glad to tell you what he has found. Let me repeat what I said
about Mr. Snyder's work, that the most valuable work that is being done
is the discovering of new varieties of nuts.

PROF. DRAKE: I shall talk about the methods I use in scoring
the black walnut in Arkansas. Color of kernel. The way I have determined
that is to first make a measuring scale. Get walnuts whose kernels show
different color. The lightest I call number one. It is quite easy to
divide them into five different groups. I feel that this grading can be
pretty well done, except possibly for the flavor, all the way through.
Applying this method to different nuts, here is the result that I have
obtained with the best ones:

I find the Stabler to rank first, with total grade points of 71.66. For
making the test with the Stabler I have had Stabler nuts from a number
of different places, Snyder, Reed, University of Missouri and nuts I
have grown myself.

The next two will be a surprise to you and I feel quite sure that after
further tests they may grade differently. The next highest is the Ogden.
I believe it was found in Kentucky in 1926 or 1927. Score of 70.90. The
Ogden nuts that I tested were thoroughly dry and gave an excellent
cracking quality, and I expect the test would go down a little bit had
they not been dried so long. I am sure, however, the Ogden is an
excellent cracker. I don't know just how the flavor of the Ogd
