THE STOCKING OF TUTIRA BY ALIEN ANIMALS 313 



The third chapter in the development of the colony was the rise 

 of the sealing and whaling industries. They were responsible for the 

 appearance of the brown or Hanoverian rat (Mus norvegicus). 



The fourth chapter was the initiation of the mercantile marine. It 

 was marked by the appearance of the mouse (Mus muscillus). 



This volume is the history of one sheep-run only ; we can, there- 

 fore, localise events and say that Tutira owes its Jciore mdori to the 

 Polynesian fleet ; its black rat to the Koyal Navy ; its brown rat to the 

 sealer ; its mouse to the mercantile marine.
