I'd be amazed if anyone at any home improvement store had even an inkling as to what variety of wood they were.

There are several woodworking websites that you could post a picture with the explanation and get opinions. www.woodnet.net
www.sawmillcreek.org are two of the larger ones with free registration and experienced members.

There is also www.hobbithouseinc.com This is a private website that is accessable to anyone for free that has pictures of hundreds of different kinds of woods.

Hey thanks, handymac.They sound helpful. Will be very happy to spend time on them. This wood has possibily.
Haha, I was just out back checking on things where the 'garage' was and the old mulberry tree just split and part fell over the the site. So now we have more wood. A real mess. I was going to work out there under the tree.

Post some pictures on Lumberjocks.com I'm sure you'll get a swift reply.

Ok,stoneaxe, it looks good. I have to wash each board to show the grain and whatever. They may not be all the same.Don't know how old the building was. Doesn't appear to have been very big from the amount of debris left behind.
