The author gives general directions for seed and plant selection, locating and 

 conducting breeding plats, and suggests an arrangement of the plats to prevent 

 the 'nbreeding of the corn. 



Pedigree seed corn, E. S. Beaven (Jour. Roy. Agr. Soc. England, 70 {1900), 

 pp. 119-1 SO). —A review and descriptive outline of the work in seed selection 

 and plant breeding in the United States, Sweden, Denmarlj, Ireland, and

The culture of the cowpea, B. W. Kilgore et al. {Bui. N. C. Dept. Agr., 31 

 {1010), No. 6, pp. 70, figs. 15). — In these experiments at the Iredell Test Farm 

 the soil from the unfertilized plats contained 0.075 per cent nitrogen, 0.041 per 

 cent phosphoric acid, 0..553 per cent potash, and 0.396 per cent lime. Among a 

 large number of plats treated with different fertilizers and fertilizer mixtures 

 the most profitable yields are stated in the following table: 



Yield of peas and hag obtained in fertiUz< r criierinienls n-illi cinrpeas. 



Higher profits were generally obtained in fertilizing for hay production than 

 for peas. The most profitable yields were obtained from the application of 

 from 42 to 70 lbs. of phosphoric acid per acre and its use alone is recommended. 

 The soil does not need potash and tests with lime do uot indicate that this
