BARLEY PLOTS. 



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

 and 1891, U bushels in 1892 and 1893, and 2 Imshels in 1894, 1895, 1896, 1897, 1898, 

 1899, 1900, 1901 and 1902. Two-rowed barley has been u.sed for seed throughout until 

 1902 when Mensury a six-rowed sort was tried. The varieties used were as follows : 

 1889, 1890, and 1891, Saale ; 1892, Goldthorpe ; 1893, Duck-bill ; and in 1894, 1895, 

 1896, 1897, 1898, 1899, 1900 and 1901, Canadian Thorpe, a selected form of the Duck-
