'ArGrand Rapids Forcing, Washington Strain 
45 days. (Illustrated on inside front 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 produced by plant 
selection by the honored W. W. Tracy of 
the Agricultural Department at Washing¬ 
ton. 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 Rapids Forcing as it 
came from the hands of Eugene 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;
