24 THE CALL OF THE SEA 



over the sea, according to their different natures, 



some fish avoid, and some seek, such a spot. If 



the sea is green from the weeds that grow at the 



bottom ... let him apply patience, and let him 



watch by the soft seaweed. Nature has designed^ 



in a varied manner, the bottom of the ocean, and 



she has not willed that all fish should frequent the 



same haunts ; for there are some that love the 



open sea, such as the mackerel, and the sea-ox, 



and the darting hippurus, and the gurnet with its 



swarthy back, and the valuable helops, unknown 



in our waters, and the hardy sword-fish, not less 



dangerous than a sword with its blow, and the 



timid tunnies that fly in large shoals. . . . 



Ovid.
