Hi Mark

The Cherry is probably still just fine, sherry is one of those woods
that don't rot overnight, however if you are able to get them off of
the ground that would be better, more important IMO is to get them out
of the sun if possible, and leave the bark on.

You say 24" around. do you mean around or diameter ?? if around then
we're talking about a 7" to 8" log and you should be able to manhandle
those, if however 24"D were talking a whole different story.

Whatever, I would in a case like this try to get them off the ground
and in the shade, then get some wood sealer and seal the ends of the
logs.(Anchor seal is one that is used a lot)

First cut of a slice or two till past any splitting, then cut off a
portion just longer than the width and cut lengthwise through the pith,
try to cut in such a way as to get equal amounts of wood on either side
of the pit, don't forget to seal the log before leaving with your
halves, then take your halve logs, chainsaw off the corners or bandsaw
into rounds and go and rough them out on your lathe, and have fun.

And so on and so on.

Have fun and take care
