preserving Ohia logs

[Wuzzerdad]

I have some driftwood logs which were brought home from the beach. They dried out naturally and has been outside in our flower bed for around 10 years. I just looked at them and they seem fine. I think the salt water has protected them from rot. Maybe soaking the logs in sea water would do the same and then let them dry out naturally? They do get rained on some but are protected by the eaves some. I dont know what kind of wood, but it still is as hard as rocks.

I started out with nothing and I still have most of it.
