LETTUCE, Imperial 456 
Heading Varieties 
IMPERIAL 456. 84 days. Newest and best of the 
Imperial types. Was developed at Cornell Univer- 
sity for those who wish to grow head Lettuce in late 
spring and summer. Heads large, solid, of light green 
color, with very prominent ribs. Has a larger frame 
and head than Great Lakes, is somewhat resistant 
to tip burn and can be sown indoors and trans- 
planted in the spring since it is earlier than Great 
Lakes. 
NEW YORK 55. 75 days. This is the variety for 
those who wish to have good quality Lettuce on the 
market first. A very early Iceberg type that has a 
small dark green head and frame but forms a hard 
solid head. 
IMPERIAL 847 (BLACK SEED). 83 days. Very 
popular in the East and South as a market-garden 
and shipping variety. Resistant to brown blight. 
Crisp heading plants of medium size; leaves smooth, 
thick, medium light green. Heads round, well 
folded; firm, low seed stalk. It is a little later than 
Imperial 44 and heads a little larger. 
GREAT LAKES (WHITE SEED). 90 days. This 
fine new Lettuce was developed at the Michigan 
Agricultural Experiment Station. It surpasses all 
other varieties in its ability to make good heads in 
warm weather. Great Lakes has very large, well- 
folded leaves and produces hard, well-formed heads 
under a large range of conditions. We are proud of 
our strain of this variety. 
JADE. 80 days. This variety will stand for a reason- 
able length of time without bolting. Outer leaves 
very large, very dark green, coarsely savoyed and 
frilled. Its resistance to cold in later stages of growth 
permits its use when low temperatures would injure 
Imperial 44. Jade has shown promise as an early 
spring crop in the Middle Atlantic States. . 
SPECIAL WHITE BOSTON 
BLACK-SEEDED SIMPSON 
LETTUCE, Special White Boston 
(WHITE SEED). 
73 days. Large, uniform, solid heads resembling 
Big Boston but earlier, lighter green in color and 
without the reddish tinge on the outer leaves. Heads 
are tightly folded so that the large, solid heart 
blanches to a bright creamy yellow; tasty, crisp and 
always tender. This is the finest of all the butter- 
head varieties. 
GREAT LAKES. 6238. 82 days. Our strain is used 
extensively in the East on account of its ability to 
withstand unfavorable conditions. Repeated plant- 
ings in all growing areas indicate this is the surest 
heading strain of Great Lakes. Plants large, vigor- 
ous, deep green. Heads good size, well covered until 
heads mature. Carries well for long-distance shipping. 
Loose-leaf Varieties 
SALAD BOWL. 50 days. Here is the perfect home- 
garden Lettuce. Easy to grow and stays in fine 
condition practically all summer. It is a slow-bolting, 
loose-leaf type that may be planted any time in 
spring or summer and can be picked early or left to 
stand, even in hot weather. Long standing, quick 
growing, attractive and fine flavored, Salad Bowl 
should be in every garden. 
GRAND RAPIDS (BLACK SEED). 45 days. The 
easiest to grow of all Lettuces. Forms a large bunch 
of intensely fringed and curled leaves which are ex- 
ceedingly tender, crisp and sweet. Grows equally 
well during the spring, summer and fall. 
(BLACK SEED). 
45 days. Splendid non-heading or cutting Lettuce 
with broad, light green, frilled and crumpled outer 
leaves; center leaves blanch almost white. Grows 
quickly, is early and of extra fine quality. We can 
recommend this variety for any section where Lettuce 
can be grown either for local market or home use. 
ALASKA. 75 days. A very good strain of head Let- 
tuce. Heads larger than Pennlake, with large frame, 
very solid and a little flatter. Leaf color same as 
Pennlake. 
We know the importance of good seed and of care in its 
production, handling and shipment. Realizing this im- 
portance, you may be sure that you will receive from us
