yielded 61.8 bu., aud among 16 varieties of oats Big Four produced the highest 

 yield, 91.33 bu. per acre. Among 5 clover varieties red clover yielded 8 tons 

 of forage per acre as compared with 4.12 tons from white clover, the lowest 

 yield. Bromus inermis proved remarkably resistant to cold and was 5 in. high 

 in 1910 before any other grass in the test commenced growth. Among 9 millet 

 varieties California produced the highest yield of forage, 5.5 tons per acre. 

 Among the G sorghum varieties Red Amber produced more than 13 tons of 

 forage per acre. Cassia Flint corn excelled 3 other varieties with a yield of 

 about 100 bu. per acre. 



Kesults of crop experiments, A. J. Nicoll (Hoard's Dairyman, Jf2 (1911), 

 No. 20, pp. 63-i, 655). — This article reiwrts results obtained by the president of 

 the Delaware County Agricultural Society and manager of the experiment 

 station work at the Delaware County Farm. 



In a test of 12 varieties State Flint Yellow corn yielded. 46.85 bu. per acre. 



In a breeding experiment 120 potatoes of the Sir Walter Raleigh variety 

 were selected for uniformity of size and shape. Each tuber was cut into 4 

 pieces. When harvested the yield from the parent tubers varied from 2 lbs. of 

 inferior to 8 lbs. of fine, smooth potatoes. One tuber yielded 24 potatoes, 19 of 

 which were marketable, while another tuber, apparently equally good, yielded 

 only 12, 1 of which was marketable. 



Report on harvest, season 1910-11, J. M. B. Connok {Jour. Dept. Agr. 

 Victoria, 9 (1911), No. 3, pp. 131-151, figs. i2).— The author reports the results 

 of field trials of the sixth year's experimental work in the northern wheat 

 areas, with diagram of the fields for the season 1910-11. 



During this year Federation wheat produced an average yield of 25.79 bu. 

 on the 12 farms included in the test, while College Purple Straw and Yaudilla 

 King yielded 21.47 and 21.03 bu. per acre, respectively. On 10 farms higher 

 average yields were secured from fields seeded at the rate of 65 lbs. per acre 

 than at higher or lower rates. Among the oat varietie^s, Garton Stout White 

 and Algerian produced the highest average yields, 33.29 and 32.24 bu. per acre, 

 respectively. 



Government experimental farms, 1910, A. E. V. Richardson (Jour. Dept. 

 Agr. So. Aust., U (1911), No. 8, pp. 135-11,1, figs. 6).— A progress report is given 

 of 3 generations of wheat breeding work based upon crosses of selected Cana- 

 dian hard reds, Indian, and Hungarian varieties on Federation, Gluyas, Yan- 

 dilla King, and other local Australian wheats. 



At the Loxton Experimental Farm, situated on the banks of the River Murray, 

 Baroota Wonder and Bunyip produced the highest yields of 24 and 22 bu. 

 per acre in a test of 9 varieties of wheat. In a test of applications to Feder- 

 ation wheat of superphosphate in amounts ranging from 30 to 150 lbs. per 

 acre, the 2 highest applications, 75 and 150 lbs., were followed by exactly the 

 same yield, this excelling that of lower rates. In a similar test with Cumber- 

 land wheat sown at the rate of 50 lbs. per acre, the highest yield, 30 bu. per 

 acre, followed the application of 150 lbs. of superphosphate" per acre, but an 

 increase of from 22 to 27 bu. per acre followed the addition of 56 lbs. of 

 nitrate of soda to 45 lbs. superphosphate and 30 lbs. of sulphate of potash. 

 Both mixtures were followed by a slightly lower yield than was secured with 

 45 lbs. of superphosphate alone. In a cultivation test wheat receiving no culti- 

 vation other than a slight stirring incident to drilling produced almost as much 

 grain as that planted on ground that was cultivated during the preceding fall. 

 Yields about 4 bu. higher were secured on ground plowed 3 to 4 in. deep. 



In a test of 4 varieties of oats, Scotch Grey produced the highest yield, 18 bu. 

 and 30 lbs. In a test of 4 wheat varieties Cumberland and King Red produced
