I guess I should have mentioned that the reason my FIL gave me these "blocks"
was that he home saws lumber, and these also were given to him, but because
they are so short, he has a hard time clamping them in the saw. He broke a
blade trying to saw one and it just wasn't worth it. He has a more than ample
supply of "logs", which he gives to his SIL's, so I can't and won't argue with
him about how to run his machine.
