Bob:
No, I have not heard of any such activity. All I know is virgin timber
that sunk on its way to the mill in Lake Superior during the 1800s makes
really good violins and other musical instruments.

Lee,
Do you know of anybody who has taken measurements of retrieved timber
from sunken ships?

question
Bob:
Get out your scuba gear. You can solve the debate about growth rates and
size of the original white pines once and for all by diving and
retrieving the mast of ships sunk in battles and storms during the
1700s. You'll be able to write a book about it and have your own TV
show too!
