ity. Mix Pulverized Hen Manure well with the soil 
and sow seed very early in the spring. For leaf lettuce, 
sow in rows twelve inches apart and do not thin until 
plants are big enough to use. Head lettuce should be 
sown in rows twelve inches apart and thinned to 
eight inches apart in the row. 
★ Grand Rapids Forcing, Washington Strain 
45 days. 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 Wash¬ 
ington. 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; 14 lb., 60c; 1 lb.,
