A sort of human caddis-worm.

A mozo laden with a freight of «  Tinajas » (as the large-sized water-jars are called) is indeed a curious sight, for the tinajas are not heavy, and he manages to carry an extraordinary number of them skilfully tied on to the outside of his cacaste, so that a back view shows only a mountain of crockery supported by two small mahogany coloured legs, and suggests a sort of human caddis-worm.
