One cannot be surprised at the large and important 

 consumption of seaweed for food by the people, when we

 is used by bakers and pastry-cooks for making biscuits, 

 macaroons, and confectionery ; by paper-makers ; in 

 stiffening the light and transparent gauzes, in the fine silk 

 which is used for making fans, screens, hangings, etc. It is
