Hi All

I've just finished cutting this years supply of wood for my stove, and some
of the tree stumps looked great I've saved them hoping to make a few
features around the garden.

I have two areas where I would like to use them, and each has its own set of
questions. I'm new to this gardening thing and I'm wondering if anyone can
advise me.

Bird Feeding table

Some of the wood I saved is willow, with the exposed surface about 15" in
diameter. I would like to use this as a bird feeding table.
Because willow is soft, do I need to treat/varnish the exposed surfaces, to
stop the rain soaking in and turning it to mush, or should I just leave it
with the cut exposed.
If I do need to treat it, is there anything I can use that once dry, won't
harm any food left on the table when it rains.

Water Feature

I would like to sit some of my other logs (beech I think) semi submerged in
my pond. Is there anything I should treat them with to stop the rotting of
the submerged bits, without it dissolving in to the pond and killing the
fish.

Thanks

Andy
