12th of June,
1745, for instance, a sum of seventy pounds had plainly become due to
some one, and there was nothing but six crosses to explain the cause. In
a few cases, to be sure, the name of a place would be added, as "Offe
Caraccas;" or a mere entry of latitude and longitude, as "62 deg. 17' 20",
19 deg. 2' 40"."

The record lasted over nearly twenty years, the amount of the separate
entries growing larger as time went on, and at the end a grand total had
been made out after five or six wrong additions, and these words
appended, "Bones his pile."

"I can't make head or tail of this," said Dr. Livesey. "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."

"Right!" said the doctor. "See what it is to be a traveller. Right! And
the amounts increase, you see, as he rose in rank."

There was little else in the volume but a few bearings of places noted in
the blank leaves towards the end, and a table for reducing French,
English, and Spanish moneys to a common value.

"Thrifty man!" cried the doctor. "He wasn't the one to be cheated."

"And now," said the squire, "for the other."

The paper had been sealed in several places with a thimble by way of
seal; the very thimble, perhaps, that I had found in the captain's
pocket. The doctor opened the seals with great care, and there fell out
the map of an island, with latitude and longitude, soundings, names of
hills, and bays and inlets, and every particular that would be needed to
bring a ship to a safe anchorage upon its shores. It was about nine miles
long and five across, shaped, you might say, like a fat dragon standing
up, and had two fine land-locked harbours, and a hill in the centre part
marked "The Spy-glass." There were several additions of a later date;
but, above all, three crosses of red ink--two on the north part of the
island, one in the south-west, and, beside this last, in the same red
ink, and in a small, neat hand, very different from the captain's tottery
characters, these words: "Bulk of treasure here."

Over on the back the same hand had written this further information:--
