 This contains an account of the location, soils, improvements, live 

 stock, garden, and orchard of the Station, and details of experiments 

 with forage })lants. grains, grasses, clovers, corn, and cotton. 



(rdi'dcii (ukI ofchard (p. 273). — In the garden fifty-six varieties of 

 straAvberries, raspberries, and blackberries have been planted. A 

 large orchard, with leading \arieties of some twelve or more kinds 

 of fruits, and a vineyard with thirty varieties have been plante<l. 



Foiuu/c plants (pp. 273-277). — Varieties of sorghum, field peas, 

 and other forage crops grown are mentioned, with notes on i)eas. 

 The results of inconclusive exi)erinients with fertilizers on sugar- 

 cane are given in tal)ular form.
