This is another reason I cut a lot of times down to one inch rounds. Once they are dry, even when they get rained on it only wets the very ends a little. If the bark is still there, they are dry inside, you can tell by the clank sound.
I just put three like that into the stove a few minutes ago, two at two inches, one at one inch in diameter. They dont last long, but throw heat just fine and light right off. A hand full of those burning and they will get larger pieces going.
OK, heres another hand full going in (this is oak), this is fully mixed into my general stacks. I have this size up to 10 to 12 inch diameter, but most is normal 3 to 5 inch splits or rounds. But the little stuff has a purpose, same as the larger all nighters. Its very easy to get, use the smallest saw, start at the top end with the tree holding the branch, up and down the branch cuts just eyeballing the cuts, it goes fast that way. It adds up! People say there isnt much wood in the branches and I disagree, theres a LOT of wood in the branches if you cut down to small, and they fit in the stacks fine.
