290 Fish Stories 



fish's wounds and make them bigger and bigger, until at 

 last the cavity of the abdomen is pierced and little creatures 

 of many kinds, plant and animal, go in there and plunder all 

 this fish's internal organs, to carry them away, atom by

But when the lampreys come up the April brook it is not 

 to feed on fishes, nor is it to feed at all. Nature is insistent 

 that the race should be kept up, and every animal is com-

The lamprey is not a fish at all, only a wicked imitation of 

 one which can deceive nobody. But there are fishes which
