I want to know the answer to the following question:
What organization tested hickory to find out about its properties?
All the background I'm provided with is that "Wide-ringed wood is often called "second-growth", because the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred.". Is that enough to answer the question?
Answer: no
