You actually put logs in yer pond
First off cut the tree, seal the ends with glue, wax, or shellac nice heavy coat, paint don't work for crap.
If the tree is big enough split it and remove the bark, on hickory becareful as the ring just under the bark is the back of your bow
and you don't want to cut through the growth ring nor nick it up too much. Once the bark is off seal the back with glue or shellac,
set it some where dry and out of the weather to dry. Osage needs the sapwood removed and then seal the back. If bugs are a problem
use an insecticide on the wood before storing them to dry. As for soaking the log the only possible advantage I see there is that it may make the bark on winter cut wood peel off easier
