the first group are those varieties which suffered very severe wood
injury. They are Clackamas, Early Globe, English Cluster, and Oregon.
The latter two are very similar and may be identical. These were all
nine year old trees located in Orchard 6. The trees were so severely
injured that their recovery is doubtful and the development of new trees
from suckers will be necessary. Clackamas evidently suffered root
killing as only one of the six trees is producing suckers. In this group
the trees leaved out, but the foliage was small, usually less than
one-fifth the size of normal foliage, and growth weak. By August the
leaves were yellow and many were shrivelling.

Varieties moderately to severely injured in Orchard 6 were Barcelona,
Kentish Cob (Du Chilly), Fertile de Coutard, Minna, Purple Aveline, Red
Aveline, White Aveline, White Lambert, D'Alger, and Montebello. In
Orchard 16 the severely injured varieties were Garibaldi, Kentish
Filbert, Marquis of Lorne, Princess Royal, Red Skinned, The Shah, Webbs
Prize Cob, Bandnuss, Einzeltragende Kegelformige, Liegels Zellernuss,
Multiflora, Schlesierin, Sicklers Zellernuss, Truchsess Zellernuss,
Vollkugel, Volle Zellernuss, Romische Nuss, Kruse and Rush. The trees of
varieties in this group were severely injured, but have a fair chance of
recovering. In many cases from 50 to 90 percent of the top was killed
outright, and new growth was weak. Most of the trees have a few fairly
strong shoots from the trunk or larger branches from which a new top may
be developed. Four out of 22 trees of Barcelona were killed entirely,
indicating root as well as top killing.

The last group includes those varieties of which less than 20 percent of
the wood was killed. The new growth was weakened slightly or not at all.
In many cases the tree is apparently uninjured and occasionally a single
tree of a variety may be severely injured while the others are unhurt.
Varieties in Orchard 6 belonging in this group are Alpha, Buttner
Zeller, Cosford, Daviana, Gubener Zeller, Gunzlebener Zeller, Gustav
Zeller, Lange Landsberger, Fichtwerdersche Zeller, Noce Lunghe, Italian
Red, Large Globe, Medium Long, Bollwiller, Nottingham, Halle, Red
Lambert, Gasaway, Guebener Barcelloner, Blumberger Zeller, Bixby, Jones
Nos. 83, 207, 269, 310, and Corylus colurna.

In Orchard 16 varieties in this group include Cannon Ball, Duke of
Edinburgh, Pearson's Prolific, Barr's Zellernuss, Berger's Zellernuss,
Beethe's Zelle
