The beaver were promptly sent to Itasca and were liber- 

 ated on Schoolcraft Island" The animals at once started off 

 to explore the lake, and in the fall they had built a house on 

 Nicollet Creek at the south end of the west arm of Lake 

 Itasca. 



Within ten years the descendants of these three animals 

 have spread over the whole west side of the park, over an 

 area of about twenty-five square miles, and several colonies 

 have established themselves outside of the park limits. 



There are now from twenty-five to forty beaver lodges or 

 houses in the park. The following can be most easily reached 

 by visitors: 



1. A large house in the pond of Sigfried Creek. 



2. A large bank house on the east arm of Lake Itasca near 

 Douglas Lodge. 



3. Two bank houses on the east side of the west arm of 

 the lake.
