Serious damage from smuts may be prevented. It lias been 

 found that the damage done to grain by smuts comes from fungi 

 developed from spores adhering to the seed of the grain when 

 sown. Dr. Jensen acting upon this fact treated grain with hot 

 water and found that the fungus spores were killed and that 

 the grain grown from seed treated thus was practically free 

 from smut while untreated seed yielded smutted grain. Experi- 

 ments carried on at the Kansas Experiment Station by Dr. Kel- 

 lermau showed that grdin could be raised comparatively free 

 from smut, by treating the seed with either Jensen's Hot Water 

 Treatment or a solution of Livers of Sulphur (Potassium sul- 

 phide). Dr. Kellerman also found that there was a considerable 

 increase in yield of grain beyond the amount that would have 

 been destroyed by smut. He describes the method of treating 

 the grains as follows : *
