- "High quality" wood is tight-grained and knot-free. These are
- characteristics of wood from trees which grow into an intact canopy to
- a very old age: the very type you can't get from a tree farm. The
- tight grain is due to the slower growth which occurs in established
- forests. "Even-aged management" (clearcutting and monoculture) gives
- trees which grow quickly into full sunlight, with a resulting loose
- grain. This is why wood from old-growth forests brings a higher price
- than the same species from a tree farm. Ask any cabinetmaker.

- I have no reason to doubt that wood that grows rapidly today isn't
- the tight-grain wood preferred for cabinet making. However, does
- Cameron Spitzer know a law of nature that guarantees that no-one
- will succeed in developing a tight-grain wood that does grow rapidly.
-
- I can't guarantee it can be done, but if I expected to be around
- in another 50 years to collect, I would offer a bet at 2 to 1 odds.
