native chestnut and some of the oaks
are dying from disease troubles. The homemaker wants to plant a tree
that will provide shade, fit well in the landscaping of the home, be a
clean tree and yet be fruitful and bear early.

The age of the tree and the growth has much to do with production. Some
pecan varieties have produced several hundred pounds per tree and the
same for black walnuts with hickory, butternut and chestnut in smaller
quantities. There are four Persian walnut trees growing in Franklin,
Indiana, that are 20 years old and have fruited continuously for the
past 10 years. The trees were seedlings, two of which are very promising
for distribution. Tree #1 produces an average of 10 pounds; tree #2, 15
pounds; #3, about 40 pounds and #4, 100 pounds. Good pollination under
common growing conditions of the Midwest and a good variety acclimated
for general planting will no doubt make a host of good friends and a
wonderful contribution from the members of the N.N.G.A.

Rootstocks for the Walnut in France[2]

J. C. MCDANIEL

[2]This is a translation, by Dr. R. T. Dunstan, of the section on
"Rootstocks" in Chapter XI of _Les Noyers_, by two Doctors of Pharmacy,
P. Peyre and E. Lancosme. This 447 page book with 140 figures was
published in 1942 by Jouve et Cie, 15, rue Racine, Paris, and is a very
complete treatise on the subject of walnuts.

The French experience with the eastern black walnut and the related
Arizona walnut as rootstocks is interesting, as is the discussion of one
method of propagation, where dormant whole-root grafts are started in
pots under glass. This differs somewhat from the indoor grafting
procedures described in our recent Reports by Mr. Stephen Bernath and
Dr. Philip Brierley. (Incidentally, Dr. Brierley tells me that he got
uniformly good grafts--96 to 100% growing--in his 1953 experiment. The
use of growth substance powder did not significantly increase the
"take". The controlling factors seem to be the use of healthy scions and
rootstocks, followed by high enough temperature and humidity to promote
rapid callusing of the grafts.)

The "old Royal Walnut" of the French is, of course, what we call Persian
(or English) walnut, and not Luther Burbank's "Royal Hybrid", the
unfortunately named cross of two black walnuts, _J. nigra_ x _J.
hindsii_. _J. torreyi_ is a synonym for _J. major_, the Arizona walnut.

Rootstocks fulfilling two essential conditions should be chosen, those
