834 ME. B. OOLLETT ON MTODES LEMMUS IN NORWAY. 



where, during the last ten years, often smaller or greater migra- 

 tions have taken place, and where sometimes their visits have been 

 of the most destructive nature. 



I do not think it will be of any service for me to enter into 

 detail in describing the different ways of each wandering, ao 

 far as it is known; for this would necessitate a somewhat exten- 

 sive knowledge in the reader of the local topography of the 

 country. I only here shortly mention the years of the greater 

 migrations of which I have any information, this being, as will 

 be seen, very iucompiete until within the last twenty years. 



1739-40. Hallingdal (from the plateau of No. 1). 



l7o7. Trondhjemsfjorden (from No. 3). 



1769-70. Osterdalen (from No. 2); at Kongsberg (from No. 1) 

 Mr. Crotch mentions (p. 158) a wandering the same year. 



1772. Soudmdr, in Bergen Stift (from No. 1). 



1774. Nordmor, in Bergen Stift, south to Satersdalen in Chris- 

 tiansand Stift (fi-om No. 1). Most likelythis and the migration 

 of 1772 have been connected. 



1780-81. Thelemarken, Eker, Hadeladed, and Christiansand 

 Stift (from the south portions of No. 1). 



1789-90. Christians Amt and about the same parts as the pre- 

 ceding wandering (from No. 1). 



1816. Nordlaud (from No. 4). 



1826. Bergen Stift (from No. 1). 



1833-34. Thelemarken and Christiansand Stift (from No. 1). 

 Mr. Crotch mentions (p. 158) a wandering the same year at 

 Bosekop in Finmark (from No, 5). 



In the last decades, I know of the following great migrations, 

 all, except the first, from personal observation in the places 

 themselves : — 



1852-53. In the south of Finmark and the tracts of Tromsci 

 (from No. 5). 



1862-64. Southern parts of Christicnia Stift (from No. 1). 



1868-69. Trondhjem Stift and the northern portions of Chris- 

 tiania Stift (from Nos. 2 and 3). 



1871. Eastern parts of Christiania Stift (from No. 1). 



1872. Trondhjem Stift and the northern parts of Christiania 

 Stift (from Nos. 2 and 3). 



1875-76. Eastern and northern parts of Christiania Stift^ 

 Christiansand Stift, and north to Romsdalen (from Nos. 1 and 2). 

 1876. East Einmarkeu (from No. 5).
