scooped up and put into the boxes and then the coquina are washed out. The 

 production of coquina in 1945 was 54,000 pounds, valued at $13,500. 



Along the coast of Florida there are considerable deposits of coquina shells 

 which have become cemented together into a solid block of limestone. This co- 

 quina limestone is highly valued for decorative purposes. In many homes lire- 

 places and mantels are constructed of the stone. One reason for the value placed 

 on the stone is due to the delicate colors which have remained in it. 



There is a small trade in octopus on the Pacific Coast. The most abundant 

 species is Polypus hongkongensis; small individuals of this moUusk are found in 

 shoal water and much larger ones in deep water. Some are caught in the Puget 

 Sound and along the California Coast. They are usually caught in traps resem- 

 bling those used in the crab fishery, and sold chiefly to the orientals who make 

 them into soup. Some are preserved by sun-drying without salt. 



A number of species of chitons, none of which is utilized to any great extent, 

 are found on the Pacific Coast. The black chiton {Katherina tunicata, Gray) is 

 gathered and eaten by the natives of Alaska. The giant chiton {Cryptochiton 

 stelleri, Middendorff ) is found on the California Coast. Its chief use is in the mak- 

 ing of curios, such as toy boats and electric-lamp shades.
