 iments conducted by the citrus substation at Rivei'side. 



During the past few seasons the vetch and pea crops in certain localities have 

 been seriously attacked by aphids and much acreage destroyed. The results 

 of the substation experiments indicate that purple vetch {Vicia atropurpurea) 

 and sour clover {Melilotus indica) are not only resistant to this trouble but 

 also yield a heavy growth for incorporation as green manures.
