The original Lamb walnut tree was curly throughout. Other trees, particularly maples and birches may be curly only in part of their trunks and sometimes only in restricted segments. Trees frequently have curly grain at the base where the trunk joins the roots but not elsewhere. Such curliness may be related to the shortening of the curve where the root joins the trunk, thus causing distortion. W. G. Bixby states (Ref. 3) that a birdseye maple tree 170 years old was only about a quarter as large in diameter as normal trees of the same age. I know of no comparison of curly walnut with other types of walnut. The original Lamb walnut tree was apparently a very large one. In conclusion, it is obvious that our knowledge of the possibility of producing curly grained walnut logs by grafting is as yet incomplete. Much more information is needed and at the present time undoubtedly much can be gained by examining the Lamb walnut trees, which are growing in various parts of the country. This can be done without seriously injuring the trees as described earlier in this paper. Those in the Northern Nut Grower's Association, who have Lamb trees are urged to examine them to find out if we can gain further useful information regarding this rather important subject. Obviously, if it is possible to grow curly walnut through vegetative propagation, we should know under what conditions a grower can expect to successfully produce a curly grained log. References 1.
