pecies, while
very large, are thick-shelled and commonly more or less objectionable
because of the frequency with which the kernels are imperfectly
developed or entirely wanting. The pignut hickory, H. glabra, already
mentioned, is omitted from further discussion because of being no better
than the sweet hickory in any known respect, and because of the frequent
bitterness of its kernel. The mockernut, H. alba, while indigenous
practically everywhere that any other hickory grows, and producing a
sweet, agreeable kernel, has too thick a shell to justify particular
attention at this time. The bitternut hickory, H. cordiformis, is rarely
palatable. The tree makes an attractive ornamental, but is relatively
unimportant in so far as timber production is concerned.

Intermediate forms of hickory and hybrids originated from chance crosses
under purely natural conditions are fairly common. Quite a good many
belonging to one or the other of these groups have been brought to light
during the last two decades, largely as a result of discovery by the
Northern Nut Growers Association. Several of these will be discussed in
alphabetical order along with varieties of pure species.

ANTHONY--The Anthony shagbark originated with a seedling tree discovered
by Mr. A. B. Anthony, R. F. D. 6, Sterling, Whiteside County, Ill. It
appears to be a particularly choice variety, and as the latitude of
Sterling is practically the same as that of Chicago, it might do very
well in the lower portion of the northernmost zone. In a cracking test
of the 1932 crop the yield of quarters was 41.66, that of small pieces
0.60, making a total of 42.26 per cent. The nuts were large, averaging
74 per pound; attractive in appearance, clean, and of nearly white
color. The cracking quality was good, the kernel plump, bright, rich in
quality and medium sweet in flavor, but not being equal to some others
in this last respect. This is believed to be one of the choicest hickory
nuts yet brought to light.

CEDAR RAPIDS--This shagbark is from Cedar Rapids, Linn County, Iowa,
where the latitude is about 42 degrees north, or about the same as that
of Chicago, Ill., Tecumseh, Mich., and the boundary line between
Pennsylvania and New York. Like Anthony (of Sterling, Ill.) the merit of
this variety is believed such as to justify its trial planting in the
southern portion of the northernmost zone.

The Cedar Rapids shagbark was discovered and brought to light by the
late S.
