Book of Buried Treasure 

Excerpt: "With the name of pirate is also associated ideas of rich plunder, caskets of buried jewels, chests of gold ingots, bags of outlandish coins, secreted in lonely, out of the way places, or buried about the wild shores of rivers and unexplored sea coasts, near rocks and trees bearing mysterious marks indicating where the treasure was hid. And as it is his invariable practice to secrete and bury his booty, and from the perilous life he leads, being often killed or captured, he can never revisit the spot again, therefore immense sums remain buried in those places and are irrevocably lost. Search is often made by persons who labor in anticipation of throwing up with their spade and pickaxe, gold bars, diamond crosses sparkling amongst the dirt, bags of golden doubloons and chests wedged close with moidores, ducats and pearls; but although great treasures lie hid in this way, it seldom happens that any is recovered."
