4 NATURE-STUDY REVIEW [14:1— Jan., 1918 



animals of prey. Those which are fortunate enough to escape a 

 violent death retire to their burrows sometime in September. 

 They close the entrances of their home and retire for a rest of over 

 half a year. In view of the fact that they are deprived of what is 

 to some the most pleasant part of the year, it is little wonder that 

 they must live an excessively active life while they can. The food 

 which supports them during their period of greatest activity is 

 largely injurious to man's interest. Aren't they entitled to a little 

 wholesome grain to satisfy their hunger in the early spring when 

 other food is scarce ? 



The little family which I had watched with so much pleasure was 

 successfully broken up by the campus cat. I arrived one day just 

 in time to see the last of the young ones caught as it came up out 

 of its burrow to see if everything was safe. In looking up some 

 references in connection with this article, I was glad to learn that 

 these squirrels are often infected with internal parasites which are 

 also parasitic and very often fatal to cats. If those which lived 

 outside my window were so infected I feel that at least they did not 

 live in vain. I only wish that they might have died early enough 

 to save the myrtle warbler, the young rose-breasted grosbeak and a 

 number of robins which I saw meet their fate at the claws of their 

 common enemy.
