Description of the garden of the Villa " Charles 

 Gamier " at Bordighera ...... 423 



Much trouble caused by forest rats which occupy 

 it in winter, leaving it in summer and never entering 

 the villa. 



Remarkable selectiveness in their taste for fruit. 



Preference for the mandarin orange and the lemon. 



The common orange disregarded so long as man- 

 darins and lemons are to be had. 



Difference in treatment of mandarin and lemon . 424 



Of the lemon they eat the rind and leave the fruit 

 in situ. 



Of the mandarin they eat the fruit and leave the 

 rind in situ. 



The occupation of the garden in winter is due to the 

 abundance of food to be found in it at that season. 



Possibility of tribes of rats being cannibals in winter, 

 the fertility of the females making up the shortage in 

 summer ......... 425 



Evidence of organization as well as intelligence 

 among the forest rats.
