and shagbark
hickories.) Sixty-two nuts from these pollinizations were planted in the
fall of 1941 in rodent-proof seed beds. In the spring, counting
germination, I found 100% of these nuts had sprouted and grown into
small trees during the season.

After finding the most suitable pollen for the Weschcke hickory, I
realized the necessity for including more than one variety of hickory in
a planting, just as there should be more than one variety of apple or
plum tree in an orchard. I think that it would always be well to have
three or more varieties of known compatibility within reasonable
distances, probably not more than 100 feet apart, nor less than 40 to 50
feet for large hickories.

Of the many varieties of hickory and hickory hybrids I have tested,
about twenty have, by now, proved to be sufficiently hardy to recommend
for this latitude. These include:

*Beaver hybrid hickory
*Fairbanks hybrid hickory
*Laney hybrid hickory
Burlington hybrid between pecan and shellbark hickory
Rockville hybrid between pecan and shellbark hickory
Hope pecan pure pecan grafted on to bitternut roots
Hand pure shagbark
*Bridgewater pure shagbark
Barnes hybrid hickory
*Cedar Rapids pure shagbark
*Weschcke pure shagbark
*Deveaux pure shagbark
*Brill pure shagbark
*Glover pure shagbark
*Kirtland pure shagbark
*Siers thought to be a hybrid between
the mocker nut and bitternut
*Stratford hybrid (bitternut by shagbark)
*Creager

*Have produced mature nuts

There are three or four others that are hardy but all means of
identification having been lost, it will be necessary to wait until they
come into bearing before their varieties will be known. As experiments
continue, more varieties of worthy, hardy hickories and hiccans will be
found which will justify completely the opinion of those of us who
always hail as king of all our native nuts, the hickory.
