 Mr. H. H. Groff, a banker, of Simcoe, Ontario, and

 gladiolus were not renewed. 



Meantime, every effort was made to extermi-

 were of course not confined to the gladiolus, and 

 through which I suffered an annual loss of cer- 

 tainly not less than a thousand dollars year after 

 year. 



Not alone with the gladiolus but with other 

 bulbs it seemed that the animals took special 

 delight in attacking the choicest plants. And the 

 question of their destruction became finally a very
