 heat and drouth best, but gives promise of being more valuable as 

 a source of grain than of fodder. 



The shortage of water for irrigation has prevented the con-

GREEN-MANURING PLANTS 



The testing of plants suitable for green-manuring was con- 

 tinued throughout the year. Especial attention was given to 

 crops to be grown in orchards for this purpose. Sowings of cow- 

 peas were made from April to August, 1899. The best results 

 were obtained from those sown August 10. The yield of green 

 matter was eight tons per acre. 



During the autumn sowings were made of lupins, yellow 

 sweet-clover (Melilotus indica, ) and alfalfa. The lupin seed was 

 imported from Paris, the varieties being the ones that had suc- 

 ceeded best at the California Experiment Station. The seed of 

 the yellow sw r eet-clover was procured at a mill from grain screen-

 vields were as follows: 



The yellow sweet-clover is plainly the best plant for the
