causes the destruction. After he
adopted that plan he had very much less winter killing in his
plantation. That might be one way of helping the situation.

Mr. Hardy: We have had some killing. Usually in the second year or the
first year after we get killing down to the ground, if we will keep the
stock pruned back to one shoot that one will make sufficient growth,
become hardy enough to withstand any cold, or perhaps sun scald. Also
wrapping the trunks of the trees with newspaper helps to prevent the
variations in temperature, which in our section is what causes the cold
injury. We don't have sufficient cold to cause absolute low-temperature
injury, but we do have sudden drops just as you do in Tennessee,
apparently, and wrapping with paper does help iron out those changes.

Mr. McDaniel: Wouldn't you suggest the paper wrap in the summer as well
as the winter and spring?

Mr. Hardy: Yes.

Mr. Stoke: It is not only the planter of the trees that has sorrows
along that line, but the nurseryman does also. I had some nursery
seedlings growing on flat land, and they looked all right, passed the
winter. When I went out to graft them I found that on these small stocks
anywhere from the size of a lead pencil to the size of a finger, the
cambium was discolored. It wasn't black nut brown. Any attempts I made
to graft those failed, and yet many of those same trees grew on. They
were stunted somewhat for a year or two, and they left a brown ring at
that annual growth.

I would say that the best guarantee against that kind of thing is to
plant your chestnut orchards--and the nurseries--to plant on land that
is well air drained. _Select the same site as you would for peaches._

Mr. Chase: I will say that we should have allowed more time for
discussion. However, we have used up our alloted time for this period.
Supper is at six o'clock, and we are due back here at 7:30. I don't know
how you folks feel about this little session, but I certainly did enjoy
it.

trees. As low as 25 pound per acre application affected growth in quartz
sand cultures, whereas with certain soils, no significant difference was
noted until an 800 lb. per acre level of the
