DR. CRANE: Dr. MacDaniels, the idea prevails on the part of some I know that this curliness would show up more at the base or crown of the tree than it would be likely to show on the trunk, and at the base of large limbs we tend to have curliness. Of course, the Lamb walnut was supposed to be curly throughout, but in the case of other trees I wonder if that's true. You have emphasized the change in the direction of the grain at the crown between the root and trunk and in the crotches. I wonder just where would be the best place to scrape this bark or pare it down in examination to determine whether it was curly or not. Would that be, in your opinion, more likely to show up on the trunk of the tree or base of some limb or near down to the crown?
DR. MACDANIELS: I'd be inclined to take it where you can work at it most easily; down towards the base. If the grain is curly only in restricted areas the log is not very valuable.
A MEMBER: I have been told by a sawmill man that he could tell by the convolutions of the bark. Instead of being straight, they would be fluted.
