for Persian
walnuts for the north. In California, the varieties of Persians, Juglans
regia L., are well rooted to the ground. They object to more northern
locations. This may not be entirely true of another species, J. hindsii,
which in the past has shown a tendency to cross with other members of
the juglans tribe. Crossed with the native black walnut, the hybrid
known as "Royal" was developed, a robust grower which bears little.
Crossed with the Persian, "Paradox" was produced. We are indebted to Mr.
Harry S. Welby, of Taft, Calif., for some interesting J. hindsii
varieties of good size and rather large, well filled kernel capacity.
Upon their exterior, the nuts resemble the Persians, and the kernel has
the Persian flavor. Inside the shell, the structure is that of the
American black, with a substantial woody cross-brace, and the shell
itself calls for a hammer for cracking. Neither Paradox nor Royal have
proved of value except for stocks upon which the growers graft or bud
their commercial cions. Much experimenting has been done in hybridizing
J. hindsii, thus far without producing more than comparatively sterile
"mules", but, the tendency to cross having been demonstrated, this work
should be continued. Mr. Welby's samples have been sent to Mr. C. A.
Reed, at the Beltsville Experiment Station, for evaluation. "Perhaps
someone will know," says Mr. Welby, "the limit of cold J. hindsii will
stand."

Mr. Welby's comments accompanying his report are too interesting to
omit. He says: "On the grounds of an oilfield camp, I have carried on
collaboration with the U. S. D. A. Bureau of Plant Introduction for
twenty years. The importation of graftwood of eastern soft shell black
walnuts has been "on my own." Of black walnuts we have bearing trees
among ornamental plantings. There has been a marked change of attitude
from the early days when I was more or less looked upon as a freak for
working with them. The nuts are valued today. The original objective has
been attained.

"In the meantime, I have purchased, 450 miles north of here, a twenty;
have fenced and planted it to a brand of permanent pasture grasses known
as "Evergreen", furnished by a grass specialist, Dale Butler, of Fresno.
Prior to the grass, black walnuts, grafted and ungrafted had gone in. A
strip bordering the highway was reserved for trees, we hope pistachio.
There are now thirty of that variety, bearing, in an interior block.

"We have for years purchased b
