BARLEY PLOTS. 



The quantity of seed sown per acre on the barley plots was 2 bushels in 1889, 1890 

 and 1891, 1^ bushel in 1892 and 1893, and 2 bushels in 1894, 1895, 1896 and 1897. 

 Two-rowed barley has been used for seed throughout the whole period. The varieties used 

 were as follows : 1889, 1890 and 1891, Saale ; 1892, Goldthorpe ; 1893, Duck-bill ; and
