'ArGrand Rapids Forcing, Washington Strain 
45 days. (Illustrated on outside back cover.) This 
splendid strain is one of the favorite strains being 
used by all of the large greenhouse growers, who 
recommend it as a superior lettuce. It was first pro¬ 
duced by plant selection by the honored W. W. Tracy 
of the Agricultural Department at Washington. Mr. 
Yonker procured some from Eugene Davis, sent him 
by Mr. Tracy. Mr. Yonker, by careful plant selection, 
has kept it up to its original purity. It is absolutely 
true to type and is more like the original Grand Rap¬ 
ids Forcing as it came from the hands of Engene 
Davis. Mr. Yonker is well qualified to continue the 
breeding of this variety and can be depended upon to 
keep it up to its present high standard. There are very 
few, if any, sports. Color a light green; heads very 
heavy; leaf crisp, tender and curly; quality of the 
best. We grow our stock seed in the greenhouse and 
send to one of the best lettuce seed growers on the 
Coast to grow the seed crop. Oz., 20c; % lb., 60c; 1 lb.,
