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. 
IMPERIAL 44 (WHITE SEED). 80 days. One 
of the earliest varieties for commercial plantings. 
Produces large, hard heads earlier than Imperial 
456 and is somewhat resistant to tip burn early in 
the season. Excellent for fall crop or first spring 
planting. Heads medium large, slightly flattened, 
well formed, heavily savoyed. 
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. 
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 
only the very finest seed it is possible to produce.

LETTUCE, Special White Boston 
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-SEEDED SIMPSON (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
