12. TANGLES. 



The tangles are employed by naturalists for the purpose of .gathering small 

 spiny animals,, such as sea-urchins and star-fishes, from the bottom at con- 

 siderable depths. They adhere to the fibers of the spun-yarn in great num- 

 bers. It has been thought that this instrument might advantageously be 

 employed in freeing oyster-beds from their worst enemies, the star-fish.
