The Labyrinth Spider
While the Epeirae, with their gorgeous net-tapestries, are incomparable weavers, many other Spiders excel in ingenious devices for filling their stomachs and leaving a lineage behind them: the two primary laws of living things. Some of them are celebrities of long-standing renown, who are mentioned in all the books.

Certain Mygales {36} inhabit a burrow, like the Narbonne Lycosa, but of a perfection unknown to the brutal Spider of the waste- lands. The Lycosa surrounds the mouth of her shaft with a simple parapet, a mere collection of tiny pebbles, sticks and silk; the others fix a movable door to theirs, a round shutter with a hinge, a groove and a set of bolts. When the Mygale comes home, the lid drops into the groove and fits so exactly that there is no possibility of distinguishing the join. If the aggressor persist and seek to raise the trap-door, the recluse pushes the bolt, that is to say, plants her claws into certain holes on the opposite side to the hinge, props herself against the wall and holds the door firmly.
