Distribution in New York. This animal is abundant throughout the 
settled part of New York. It is by no means strictly confined to 
buildings. 
Principal records. De Kay: “ This familar little species has also been 
introduced from Europe into this country since its discovery. It has 
everywhere followed the footsteps of man . . .” (’42, p. 82). Merriam: 
“‘ T have observed the house mouse in many of the camps scattered through 
the Adirondacks and have killed it, though rarely, at a considerable dis- 
tance from the habitations of man. It iscommon in the fertile valleys along 
the outskirts of the wilderness, living in the fields during the short sum- 
mer season, and returning to the dwellings, barns and haystacks at the 
approach of winter” (84, p. 162). Fisher: ‘Common in the corn andrye 
fields as well as around buildings” (’96, p. 197). Mearns: “‘ Common in 
fields and houses. Several were trapped under stacks of fodder corn 
standing in the fields. None were caught in the woods” (’98b, p. 351). 
I have found the house mouse abundant at Geneva, Ontario co. 
Peterboro, Madison co. and Elizabethtown, Essex co. 
Mr Savage reports it abundant at Buffalo. 
Helme: ‘‘ The house mouse is abundant on Long Island.”
