Hi Paul & All, Sept 26, 2012
Someone who knows about the days of iron men & wooden ships may know =
better but I think the spars (not masts) were usually made of Spruce. =
Oak was for ribs, brackets & planking but not for superstructure.
And on the subject of slow growing trees some good examples can be =
found on the barrens between the Clyburn River in Cape Breton and =
Two-Island Lake. I camped there a few times, in a previous life, and one =
dead hip-high spruce tree about 100 years old and 10 mm diameter would =
boil a pot of water for oxo or tea; almost solid wood.
Getting back to Oak, it may sound counter-intuitive, but wood from a =
rapidly growing Oak (probably all trees) is stronger than wood from a =
slow growing tree. I suspect this is because wood from a tree with wider =
rings is more supple, i.e. can bend without breaking whereas wood with =
mostly thick-walled cells is more brittle.

Subject: Re: [NatureNS] old oak
You started a very interesting discussion Heather
Nothing anyone said rules out a 400 year old oak. Documented=20
trees 300 plus leave quite a bit of variation possible in the
dying age. The half life will be much less of course but ones
at the end of the scale might easily get over the 400.
Oak in the 1800 - 1875 period of wooden ships were sought
wherever they could be found. The beautiful fall foliage made it
hard for them to hide! And the lads were good at handling big logs.
They didn't get spars at the building supply store.
They removed most of the large oak at that period especially=20
where it was easy to do - PEI for example, no stones, hills not too =
steep=20
and lots of horses and a good demand.=20
I would be susprised if you could find one there over 200 years old.=20
And to see some of the things I see in the deep woods make me
believe there wasn't much of NS left to chance for a big tree. Spruce =
or oak!
Have a nice fall
Paul

As we speak, it could be being up rooted. I had not realized how big =
