one on this disease in the East prior to
this summer. That it must have been here for a long time seems almost a
foregone conclusion, because of its wide distribution. Mr. Jones was a
little bit conscience-stricken for fear he brought it here with him.
Still it is in Delaware and Maryland as well as Pennsylvania, and you
can't blame Mr. Jones for that. I think, too, it is less actively
pathogenic than on the Pacific Coast, or we would have heard of it
before. That it should prove a serious menace to the development of the
walnut industry in the East, is too much to assume at this time. It will
undoubtedly eliminate a number of the varieties that are considered
promising now, but the course that will have to be taken will be to
propagate only varieties which are highly resistant or totally immune to
the disease. Just what these varieties are going to be in the East we do
not know as yet, of course. We should avoid the mistakes that the
growers on the Pacific Coast have made of planting seedling trees, and
taking the chance of their being resistant to the disease. A great many
varieties will be automatically eliminated when the nurserymen bear in
mind that this disease is one to be considered, and I want to say, that,
in addition to this, the Department will take pleasure in making
artificial inoculations and tests on all those concerning which there
is any question. We have the germ in culture now and will maintain it,
and anyone who discovers a new variety, or has an old one they would
like to propagate, can communicate with us, and we will take pleasure in
testing its susceptibility.

I think that is about all that can be said on the subject at this time.

This disease has been studied very carefully on the Pacific Coast and a
number of publications issued from the California Experiment Station
concerning it.

For those who are interested in looking the literature up, I have here
the following references: Cal. Station Bulletins, 184, 203, 218, 231,
and Circulars 107 and 131.

A MEMBER: Is spraying of any avail?

MR. MCMURRAN: It has helped somewhat, but it has not proved economical
on the coast.

A MEMBER: In order to have that test made, would it be necessary to send
the things to the Department?

MR. MCMURRAN: No; it would be necessary for me to come to you and test
them on the trees.

MR. LITTLEPAGE: Did those walnuts in Mr. Brown's yard look to you as
though they had the blight?

MR. MCMURRAN: Yes, they
