Tri-State’s Lettuce 
ee 
Pennlake 
75 days 
The result of a cross of Great Lakes by Imperial 
No. 847 made at Pennsylvania Agricultural Experiment 
Station. Much more uniform in plant and head type, 
insuring many marketable heads at first cutting. The 
compact heads are of excellent quality, with dark 
green, smooth foliage and without objectionable rib- 
biness. They are protected from scald by broad en- 
folding wrapper leaves. Pennlake may be grown 
unusually free from tip burn as an early summer crop 
from plants or seeded directly in the field. It also does 
well as a fall crop in field or frames and is adapted to 
home and market-garden use on upland or muck soils 
throughout the United States.

Premier or Smooth 
Great Lakes 
80 days 
This strain is recommended for growing on upland 
soils as an early-maturing crop either transplanted or 
seeded. This variety produces heads from 7 to 10 days 
earlier than standard Great Lakes. Bred also for re- 
duction in ribbiness and for uniformity of heading. 
It has produced better than 90 per cent marketable 
heads at first cutting. The heads are unusually solid, 
practically round, up to 7 inches in diameter and 2 
pounds in weight. Outer leaves are somewhat flattened, 
smooth and without ruffled margins. Due to its slow 
bolting habit and resistance to tip burn, it may be 
planted in succession for a summer crop in widely 
diversified areas.
