NUT TREES 
The production of grafted nut trees ceased during the war period 
because all available man power was needed to grow quicker yielding 
food crops or trees. Producing grafted walnuts and hickories in partic- 
ular, requires much experience and time, as well as favorable weather 
conditions. Then they can not be dug by mechanical diggers as the 
fruit trees can, but have to be dug by hand, which is slow because of 
their deep tap roots. 
We were able to grow some stocks which are now ready for graft- 
ing and expect to resume some of this work in the spring. 
BLACK WALNUTS. The better varieties of Black Walnuts and 
particularly Thomas has been grown long enough that people have 
learned how superior their nuts are to common walnuts and are calling 
for them more and more. Thomas is not adapted to every place but does 
seem more cosmopolitan than most horticultural varieties. Some vari- 
eties may be superior in a limited section and quite ordinary elsewhere. 
We suggest that more than one variety be planted to be more sure of 
pollination. 
Practically no grafted trees are available this spring. 
HICKORIES. The hickories are the most difficult class of nut trees 
to propigate and transplant but once well established are very persist- 
ent. There are several species each with some varieties which have 
been propigated. The Shagbarks are the best and in fact, the best of all 
nuts. Schinnerling, Hagen, Wilcox, and Stratford are among the best 
ones. The large thick shelled Shellbarks have less horticultural value 
for the nuts are quite inferior in quality to the Shagbarks. Hybrids of 
the Bitternut such as the variety Fairbanks, are attractive, easier to 
grow, and very productive, but the trace of bitterness in the meats 
spoils them for many people. 
PECANS. Pecans are not very satisfactory north of southern Iowa 
because they bloom so late in spring that there is not sufficient time for 
them to mature before freezing temperatures in the fall. This is true 
of the most northern varieties and those from farther south can not be
