of Agriculture at the Experiment Stition have been very helpful in 

 listing the numerous genera and species of nut trees as they have 

 located them in checking up on the flora in making up soil maps of 

 the different counties. Colleagues in the Department of Horticulture 

 have also added to our list of nut trees as they have observed them. 

 An extensive correspondence among the members of the Northern Nut 

 Growers' Association, county farm advisers, and others interested in 

 nut growing in the state has been of assistance. 



It is hoped that we will be able to prepare a detailed county map 

 of the state showing (1) the native range of the most important nut 

 bearing trees, and (2) the most important areas where such trees are 

 being successfully grown outside their natural range because of local 

 conditions favorable for growth and fruiting. We are also attempting 

 to gatlier figures as to the commercial joossibilities of nut culture in 

 Illinois. Much of this information is in progress of tabulation and 

 no definite conclusions can be drawn as yet in answer to all questions 

 being asked. 



A number of interesting facts have, however, been gathered and 

 are h.ere submitted in the nature of a progress report. 



Nut bearing trees native to Illinois include the shell bark hickory 

 Hicoria laciniosa (C. laciniosa Cy), the shagbark hickory, H. ovata, 

 (C. ovata Cy), the mockernut, H. alba, (C. alba Cy), the bitternut, H. 

 cordiformis, (C. cordiformis Cy), the pecan, H. pecan, (C. pecan Cy), 

 the American sweet chestnut, Castanea dentata, the black walnut, 

 Juglans nigra, the butternut or white walnut, J. cinerea, and the beech, 

 Fagus americana (F. grandifolia. Cy-Ag.) 



Smaller trees or large shrub-like forms include the Chinquapin 

 chestnut, C. pumila, and the American hazelnut, Corylus americana. 



A numiber of hickory and black walnut sj^ecies hybridize rather 



freely. There are .some excellent natural hybrid varieties in the 



trade showing indications of the pecan-shell bark hickory and the 

 shag bark-bitternut crosses. 



Nut bearing trees not native to Illinois but varieties which are 

 promising for planting in different sections include the European 

 filbert, C. avellana, the Japanese walnut, J. sieboldiana. the Chinese 

 walnut, J. cathayensis and the Japanese heart nut or flat nut, J. 

 cordiformis.
