al
leaf on a scion seldom died until it had functioned for at least a week.
Some of them functioned for more than two weeks and one of them for at
least four weeks, failing only a day or two ago. This would seem to mean
that the terminal leaves in scions conducted or helped to conduct repair
in green graft wounds to a point where buds are now bursting on two
persimmon scions. Two pawpaw scions have enlarged buds to the point of
bursting. The terminal leaves on scions seemed to conduct repair up to a
point where lignifying for the winter is now going on. This cannot be
determined until winter passes but I have never obtained anything like
this effect until experimenting with the terminal leaf theory for the
first time this year. The most striking effect so far as appearance goes
is with the English walnut grafts with their bright green stems.

If I may have opportunity for conducting experiments next summer I shall
begin earlier by pinching off the buds of growing shoots, giving them a
week of rest and then cutting these shoots up into scions. If buds then
start off like those of two persimmons and two papaws they will have
time for lignifying.

My whole lesson of this season would seem to mean that after properly
checked experiments we may perhaps add what I call "green grafting" to
the other form of immediate grafting. The practical feature of this
whole new phase in grafting method is an extension of the grafting
season to include every month of the year. Scion grafting of perennials
in the latitude and longitude of Connecticut had formerly been confined
to about two month's in the farmer's rush season, and with general
failure in the grafting of some species which may now be grafted
successfully.

_Letter from Prof. Colby_

_Agricultural Experiment Station Urbana, Illinois_

I regret very much indeed that I cannot attend the meeting of the Nut
Growers Association this year. This letter bears my very best wishes and
hopes for a successful meeting. We shall miss Mr. Bixby's pleasing and
helpful personality. Some time ago I promised to give you a report on
some of our activities here and if you think it is worth while, I would
appreciate your reading it to the group.

There is an increasing interest in nut culture in Illinois. Wholly aside
from the commercial aspects which have been so profitably developed in
southern Illinois is a project of recent development, one in
