But the shyest and most self-effacing of the wall community were the most dangerous; you hardly ever saw one unless you looked for it, and yet there must have been several hundred living in the cracks of the wall. Slide a knife-blade carefully under a piece of the loose plaster and lever it gently away from the brick, and there, crouching beneath it, would be a little black scorpion an inch long, looking as though he were made of polished chocolate. They were weird looking things, with their flattened, oval bodies, their neat, crooked legs, the enormous crab-like claws, bulbous and jointed neatly as armor, and the tail like a string of brown beads ending in a sting like a rose thorn. The scorpion would lie quite quietly as you examined him, only raising his tail in an almost apologetic gesture of warning if you breathed too hard on him. If you kept him in the sun too long he would simply turn his back on you and walk away, and then slide slowly but firmly under another section of plaster. I grew very fond of these scorpions. I found them to be pleasant, unassuming creatures with, on the whole, the most charming habits. (153)
