34 INLAND FISHERIES. 



to color the sea red, a degree south of Valparaiso, accords exactly 

 with that of Perulhmiin. The animalcules which, according to 

 Salt, produce the red color in the Red Sea, may be this form, 

 and the same cause may perhaps be ascribed to the red color of 

 the sea off Iceland in 1649. Carter quotes the following passage 

 from an eye witness of a similar occurrence at Porebunder, on the 

 coast of Khattywar, India, where the red water is extremely com- 

 mon : " The color of the sea water on Saturday evening last, the 

 27tli of October, 1849, was changed from its usual tint to a deep 

 red, emitting a most foul smell ; the fish speedily were all destroyed 

 and washed upon the beach in large quantities, etc." Though the 

 narrator believed that this might be due to a submarine eruption 

 of mud, Mr. Carter is inclined to ascribe it to some " animalcule," 

 most probably Peridinium. He also directs attention to the Mosaic 

 account of the plague of Egypt given in the following verses : 

 " And all the waters that vere in the river were turned to blood." 

 " And the fish that teas in the river died ; and the river stank, and 

 the Egyptians could not drink of the water of the river ; and there 

 was blood throughout all the land of Egypt.'"

Early in the investigation of the starfish problem it became ev- 

 ident that the starfish are not evenly distributed throughout the 

 Bay, but that there were certain centres of distribution from 

 which they migrated, often in great numbers, to adjoining mussel 

 and oyster beds, and where during the breeding season they car- 

 ried on the process of reproduction with great activity. The 

 question naturally arose : — If the starfish in these areas of distribu- 

 tion and centres of reproduction could be exterminated, would 

 they l)e eliminated permanently, or only temporarily owing to 

 constantly recurring invasion from the outside waters through the
