I. Burnley. — There were seven plots of each variety sown; in two 

 of them the ordinary seed was used as a check, while in the others the 

 seed was thoroughly dusted with bunt spores. Both T. tritici and 

 T. fotttns were used for infection, but no conclusions as to their relative 

 virulence could be drawn from the results of a single season's experi- 

 ments. 



The general average for the whole of the plots was over 5 per 

 cent, for Florence and over 6 per cent, for Genoa. If the comparison 

 is strictly confined to the plots on which T . foetens was used, as at 

 Dookie and Longerenong, then Florence had 5'66 per cent., and 

 Genoa 4'72 per cent., of stinking smut. In all cases the ordinary 

 seed was sown as a check, and the plots were invariably free from 

 bunt. 



II. Dookie. — There were also five plots of each variety sown here 

 to test their susceptibility to bunt, and only T. foetens was used. In 

 order to make the test as severe as possible, some of the grain 

 already dusted with spores was resmutted in the following manner : — 

 One hundred smut balls were powdered and then made into a soft
