??? on growth rings
duffontap:
Two cents worth:
Large trees put on mass faster than small trees because they have larger systems to take in more nutrition. A 1/32" growth ring on a 4' diameter tree 200' tall represents much more actual mass than a 1/2 growth ring on a 4" tree that's 20' tall. Logging companies cut their trees while they are still young, not because they grow too slowly when they are mature, but because the interest on their investment maxes out at about 30-40 years.
Yew is often judged loosely on its ring count because tight ring count is sometimes a clue to its density. Soil nutrition, genetics, availability of sunlight, and a dozen other things contribute to a woods density. Yew (and other woods) can be dense at 10 rings per inch and light and flimsy at 150 rings per inch.

Tom Thumb, you sure do alot of observing?:)
Skeaterbait:
So how do you tell the difference in summer and spring rings?
Roger:
On Osage the darker rings are the latewood which are transformed each year from the lighter spring growth in the sapwood...The thin yellow rings are the spongy earlywood rings.

Boy Roger, I would take a ratio like that any time. If you get wood with thin early rings like that you cant go wrong. With hardwoods like Osage and Mulberry I also look at the darkness of the late wood. If you see the real dark color like in Rogers sample it is good. Sometimes you will get some that looks bleached out, it usually sucks. That is the reason why nothing is better than experience. Even with my limited experience I can see the difference. I can only imagine what you guys that know what you are doing can see. Justin
