Observations. This animal is still numerous in our marshes and 

 mill-ponds, though it is hunted with a good deal of avidity. It 

 makes holes or burrows in the banks, and sometimes builds 

 houses with some ingenuity in the marshes, which appear like 

 little hillocks. From these habitations it may be driven by being 

 disturbed, and makes its escape by plunging into the water. The 

 fur of the Muskrat is quite fine, and is used in various ways. In 

 August, it is sometimes preserved on account of its pale color. 

 It is not till November that it is good, and it is still more valuable 

 in the spring.
