The great spiders of the Antilles, without piquing themselves on 
accomplishing a work of purification so terrible and so complete, labour

ability, its prescience of atmospheric variations and climatic phases, 
have so exalted the idea which the Siberians have formed of it, that 
many of their tribes refer the creation of the world to a gigantic spider.
