What does the book contain?

The book contained a running account of all the attacks and plunder the pirates had collected over the years.

"The thing is as clear as noonday," cried the squire. "This is the black-hearted hound's account-book. These crosses stand for the names of ships or towns that they sank or plundered. The sums are the scoundrel's share, and where he feared an ambiguity, you see he added something clearer. 'Offe Caraccas,' now; you see, here was some unhappy vessel boarded off that coast. God help the poor souls that manned her - coral long ago."
