. Jones for some time. But did any one ever
see a shellbark that bore well and filled the nuts? Shellbark trees are
beautiful to look at, have enormous leaves, seven to nine leaflets, but
they leaf out early in spring and the flowers are frequently killed back
by spring frosts. Part of its flowers are killed outright with too great
frequency for it to be worth growing for the nuts. These are very large,
the hulls split entirely to the base, and what kernel there is, is of
sugar-like sweetness. The shells are mostly thick and the kernels seldom
well-filled.

The Glover shagbark hickory, from Connecticut, which was introduced by
Mr. Jones in 1918, is undoubtedly one of the best shagbarks yet
propagated. The nuts are of medium size and shell thickness. The flavor
is very good. Most shagbarks have five leaflets; this one has seven
quite as often, and the leaf is about a foot long.

There were other hybrids, or what are supposed to be hybrids. The Pleas
hickory, introduced in 1916, was perhaps first successfully grafted by
Mr. Jones, but credit for introduction went to the owner of the parent
tree, Dr. E. Pleas, Collinsville, Oklahoma. It was a beautiful tree,
shapely, with an air of considerable refinement, making it a graceful
lawn tree. It bore fairly well, although not heavily. The nuts were
thin-shelled and also had thin hulls that split entirely to the base. So
far as most laymen are concerned, the Pleas may be but an edible, or
semi-edible bitternut. On the grounds of the Plant Industry Station, at
Beltsville, Md., there were once two trees of Pleas, but they were given
to the Wild Life Service for planting 10 miles away, although there are
many native bitternut trees just over the line fence in neighboring
woods. We fancied that we could detect bitternut flavor in good
shagbarks about the plantings, due to xenia influence, as in the case of
chestnuts.

Burlington was another hican first propagated by Mr. Jones, in 1915. It
came from eastern Iowa, and for a time was confused with Marquardt,
which never was propagated, or apparently not. Burlington makes a fine
appearing tree and serves well for ornamental purposes. It bears fairly
well while young, but soon develops faulty nuts, few being well-filled
and the majority weevil infested. It is also subject to shuck-worm and
twig girdler injury.

Mr. Jones once wrote that he had given up with the hickories "in
disgust." So far as is known, he never used any stock for h
