Symbolic of the care and precision exercised in field testing and evaluating strains is this photo- , 
graph of pea trials on one of our Twin Falls, Idaho, breeding farms. New varieties are originated : 
and tested. Each lot and each strain of existing varieties is tested and evaluated. Many thousands : 
of test plots are grown and observations recorded annually in the West and at Keystone Valley 
Farm near St. Louis. This work proceeds ceaselessly so that you as a user of Keystone seeds 
may be sure of the best. . 
Symbolic of the 106 years of continuous seed service to agriculture by our company and its 
immediate predecessors is the Keystone emblem which stands as your protection and assurance 
of supreme quality and value.
