Thanks guys for all the info.  I cut the tree and sealed the ends with carpenters glue, but I have not split it in half or quarters yet.  To be honest, I ordered the Traditional Bowyer's Bible a few days ago, and I was hoping it would show up before I really got started.  (Don't know why, there is probably three times as much experience in this forum every day)  Should I treat the log with insecticide now or should i split, strip the bark, then treat?  Once again, thanks for all yr help!  David
