When a pirate buries his treasure, it is not for forever; he expects to come back for it. It may take some time before he can return—there are many ships to rob and his own vessel’s speed is limited by the winds—so it is important that he prepare for an almost inevitable occurrence: that he will forget where he buried for it.

How does he prevent that from happening? Well, the organized pirate makes a treasure map.

And not just any treasure map. If the pirate is also clever (and if he is alive, he most certainly is; most dumb pirates will quickly end up dead), he will incorporate some sort of code into his map. That way, if it falls into enemy hands (a competing raider’s, say), the location of the chest of gold (or what have you) will not be immediately revealed. In the time it takes to decipher it, the original pirate can track down the thief (who, most unfortunately, will probably end up walking the plank) and reclaim his map.

Even for non-pirates, making a secret map to protect one’s buried treasure is a pretty good idea. Except for certain buried treasures.

I’m talking, of course, about flowering bulbs.

When I bury a chestful of these little golden orbs, I want to forget where I left them. One of the greatest joys of planting bulbs is the exhilarating jolt of surprise when the blossoms are first sighted in late winter or early spring, usually pushing through a crust of snow. Having a map that gives their locations away would spoil half of the fun, for me anyway.

Now, that doesn’t mean that I want to leave my buried treasures susceptible to theft. If I thought it would help prevent the squirrels from stealing my precious stash, I would employ the most enigmatic map I could devise.

And if I still caught them plundering my treasure?

Arrgh! I would send those marauding squirrels to Davy Jones’ Locker!
