VII.— AT POTCHEFSTROOM, TRANSVAAL. 



Field Experiments. 



In conjunction with the Chemistry Section, a manurial rotation 

 experiment is being carried out on eight acres of dry-land. 



Grasses. — Several plots of pasture and other grasses are under 

 observation. Kikuyu, Natal, Fescue, and Phalaris grasses are doing 

 remarkably well. 



Lucerne. — Another ten one-twentieth acre plots of lucerne have 

 been laid down to observe the variety, characteristics, difference in 

 growth in local and imported seed, longevity, and frost and drought 

 resistance. 



Clovers. — Eight one-twentieth acre plots of clover have been laid 

 down during the past year; all the varieties seem to suffer from severe 

 frosts and heat. 



Peanuts. — Five varieties of peanuts were grown as a variety trial, 

 and two acres were planted for the purpose of increasing the supply of 

 seed. 



Mangels. — To produce seed bearing strains of mangels, several 

 varieties have been grown for purposes of selection. A seed produc- 

 ing strain is now being fixed. 



Kale and Rape. — These crops have been grown in a " distance 

 trial " and seeding test. 



Beans.- — A large number of bean varieties have been grown, but 

 were not successful, owing to the drought. 



Fibre Plants. — Several of these were grown and samples have 

 been sent to the Division of Botany, Pretoria, for the purpose of fibre 

 extraction. 



Cowpeas. — This pulse is doing remarkably well ; eight varieties 

 were included in the variety test. About one acre of the iron variety 

 has been grown for seed.
