The German carp is different. The glochidia do notattach to the gills, but 200 to 500 will attach to the finsin about forty minutes. It will be observed that the lifeof the mussel is not only a very interesting one, but alsoone that is in almost constant danger. The manychanges that must be wrought throughout its life and themany dangers which it must pass through tend to makethe life of a mussel a life of chance, and we wonder howso many of them happen to reach CHAPTER and Enemies of Mussels. THE very talented naturalist, Ernest ThompsonSeton, has written many stories about the wildanimals of America. His stories are very inter-esting and are the result of a thorough study of the livesof the wild animals. It has been said that this famousnaturalist maintains that no wild animal ever dies anatural death. There have been many instances in whichwild animals were killed by other animals, or have mettheir death through some other disaster. Possibly thestatement is true in all instances. In the case of the mussel there are so many perils andenemies that the theory seems to apply very soon as the glochidia leaves the shell of the molluskthey are exposed to their greatest peril. At this timemillions of glochidia perish by not becoming attached asparasites to the fishes. Even after clasping on the fila-ments of the gills or on the fins of the fishes, many losetheir lives before the parasitic period is com
