the cool side of any particular planting,
because if you can hold them back more, you have got a better chance. If
you plant them on the south side, you rarely get anything.

MR. SLATE: The hybrids bloom later than the _avellana_ varieties, and
they mature nuts later. Is that your experience?

MR. GERARDI: That's true, I will admit your hybrids are a little later
blooming, because your American hazel nuts around our place bloom very
early, sometimes in January in full bloom.

MR. SLATE: _C. avellana_ starts blooming in March and blooms for about a
month. Some years when you have had considerable open weather, they have
bloomed as early as the middle of February. They will, of course, stand
considerable freezing when they are in bloom.

As regards the pollination, I believe about all the information we have
is the work that was done at the Oregon Experiment Station a number of
years ago. All of the varieties tried were self-unfruitful or
self-incompatible. The term, "self-sterile" is often used, but I think
it is a little more exact to say self-unfruitful or self-incompatible.
They are not sterile, because the pistillate flowers are normal and so
is the pollen produced by the staminate flowers. It's just a question of
inability of the pollen to fertilize the pistillate flowers on the same
variety.

We know nothing about the pollination requirements of any of these
_Corylus avellana_ or _Corylus americana_ hybrids. We do know that when
the cross is made that the _Corylus americana_ variety must be the
seed-parent. The cross doesn't work the other way around. That's about
all we know about the cross-pollination of these filberts.

MR. SAWYER: We have had them to bloom in April or the first week in May.

MR. SLATE: The seedlings?

MR. SAWYER: The seedlings.

MR. SLATE: What is the origin of the seedlings?

MR. SAWYER: They are the natives.

MR. SLATE: The native _C. rostrata_, or _C. cornuta_ to some botanists,
it seems to me has nothing that we want in the way of a nut, if we can
possibly grow these other varieties, the _americana_ selections or the
hybrids. It's a miserable little nut with that long, prickly husk. It's
very difficult to get the nut out of it. For that reason, I have never
been very much interested in it.

MR. SAWYER: How is the Ryan?

MR. MCDANIEL: Mr. Gellatly out in British Columbia has named several
hybrids between _avellana_ and the _Corylus cornuta_. Have you seen it?

MR. SLATE: No,
