136 TRANSACTIONS OF THE 
Many more interesting exceptions to the rule of life 
history and of structure might be mentioned, but the above 
will be sufficient to call attention to some of the important 
ones, which have shed new light on the entire subject. In 
our own State, but little work has been done on this im- 
portant and most interesting group if plants. Probably 
many species occur in the State that at present are unknown 
to science. No attempt has been made by most of the bot- 
any teachers of the State to germinate spores, or attempt 
culture work of any description. And yet no field for 
original investigation offers more unsolved problems to 
tempt one than that of the rusts. It is to be hoped that 
some attention may be given to the subject by the botany 
teachers of the State, who can be assured in advance that 
they will find plenty both to interest, to puzzle and to re- 
ward them. ;
