DISEASES OF OATS AND WHEAT 235 



NOTE TO THE TEACHER. If you can get the promise of some farmer 

 to sow half an acre of smutty oat seed and an acre alongside with seeds 

 that have been treated for smut, your State Experiment Station may 

 possibly be able to send you the necessary formalin. Or you can ask 

 certain pupils simply with the aid of a borrowed thermometer to scald 

 the seed for this test. If you have a school garden, plant in it treated 

 and untreated oat seed. Let different pupils plant the two kinds of 

 seed, so that disease germs may not be carried from the untreated to 

 the treated seed.
