Testing of the vitality of grain and other seeds, W. Saunders 

 {Canada ExpiL Farms Rpt. 181)3, j)}). ™\v, ;j9). — During the past season 

 the vitality of 1,975 samples of grain and agricultural seeds, from 

 almost every part of the Dominion, were tested and reported upon. 

 The average vitality of all the samples was a little lower than the 

 average of the previous year. Tabular information is given as to the 

 number of samples, the percentage of germination, and the average 

 vitality. Six hundred and thirteen samples of wheat were tested, hav- 

 ing a vitality ranging from zero to 100 per cent; 383 samples of barley 

 varied in vitality from 22 to 100 per cent, and 744 samples of oats
