that the hibernating animal is occasionally aroused 

 from his torpidity to relieve his physical uneasiness 

 in this respect. Dr. C. C. Abbott agrees with him 

 as to the necessity of occasional relief, but says 

 that a series of observations in 1872 led him to 

 believe that this forced discharge was made by the 

 skunk into a hole dug for the purpose, where it 

 was carefully covered over. This strikes me as a 

 credible, and, indeed, very natural example of pru-

 dens are rarely any more offensive to the nose than 

 is the home of a weasel or marten. 



He is a persistent digger, and delights to scratch
