A lay is a lyrical, narrative poem written in octosyllabic couplets. Amiral, on the other hand, is definitely a typo that I and my crew of pirate editors missed somehow.
Huh that's a new one for me, I did look it up but missed that line in Webster. My apologies to you and your pirates!
No apologies needed, the presence of a a few other typos made it very possible.
