The Colorado Experiment Station 
should prove to be very much better than all others, this should 
be saved for seed and increased to the fullest extent possible. In 
this way the entire bean acreage will soon be planted from this 
high-yielding, early-maturing, even-ripening, disease-free strain. 
Preliminary work with bean selection shows that it is easily 
possible to increase the yield 25 per cent by selection alone. To 
increase the yield this much would pay for all of the extra work of 
starting a seed patch and testing out in comparative tests the var¬ 
ious selections, thus enabling the grower to pick out the highest- 
yielding strain of his crop from which he may eventually plant 
his entire crop. It will pay to hand select seed to get seed of 
uniform marking, uniform size and freedom from disease, even if 
time and conditions do not permit the better work of the selection 
of pure, high-yielding strains.
