NEWLY DISCOVERED EVIDENCE. That evidence which, after diligent search for 
it, was not discovered until after the trial of a cause. 
     2. In general a new trial will be granted on the ground that new, 
important, and material evidence has been discovered since the trial of the 
cause. 2 Wash. C. C. 411. But this rule must be received with the following 
qualifications: 1. When the evidence is merely cumulative, it is not 
sufficient ground for a new trial. 1 Sumn. 451; 6 Pick. 114; 4 Halst. 228; 2
