LETTUCE 
Our lettuce seed is produced both in the Inter-Mountain area and in California, and our 
stocks are carefully tested in our Minneapolis Trial Grounds. We attempt to have avail- 
able the best possible stocks of both the new strains of tested adaptability and the older 
standard varieties. Days to maturity indicate average time to produce edible heads or 
leaves under Minnesota conditions and denote comparative earliness. Symbols b.s. indicate 
black-seeded; w.s., white-seeded.
