LETTUC 
Sow 1 to 2 pounds per acre. 
Pennlake 
The best early lettuce for upland. 
533 PENNLAKE. Hara Heading Early Iceberg. 
77 days. Upland growers have chosen Pennlake in preference to all 
others for their early crops. Its uniform, attractive heads are better 
than anything in its class, good sized, compact and of choice quality. 
The leaves are crisp and dark green, moderately blistered and fringed 
at the edges. They fold over tightly to make firm handsome heads 
that have considerable resistance to tip-burn. 
Developed by Prof. M. T. Lewis of Penn State College, Pennlake 
forms slightly flattened heads that mature evenly and are ready to cut 
very early. They have a remarkably fine quality and texture. We can 
recommend this as an outstanding variety. 
Pkt. 15c; 14 Oz. 45c; Oz. 80c; 14 Lb. $2.15; 14 Lb. $3.25. 
520 GREAT LAKES. The Best Heading Kind for Summer. 
A packet will sow about 30 feet of row; an ounce 250 feet. 
Even the smallest of home gardens can easily grow plenty of lettuce 
and by making successive sowings you can have a supply of lettuce 
throughout the season. The loose leaf varieties may be thinned four to 
six inches apart when they come up and then every other one taken 
out and used as they get larger. Thin the heading varieties 12-18 
inches apart in the row while the plants are still small. Be sure to give 
them plenty of room or they will not make heads. 
“Tceberg’’ Lettuce is a general term used by growers, shippers and 
merchants for many kinds of crisp-heading lettuce and does not mean 
any particular variety. This year we offer the following excellent Ice- 
berg lettuce varieties: Pennlake, Cornell 456, Imperial 44, Great Lakes 
and Premier Great Lakes. 
HEADING VARIETIES 
508 CORNELL 456. Heat-Resistant. For Muck and Upland. 
76 days. By far the best variety for growing on muck in the East, this 
tip-burn resistant lettuce can be grown throughout the season from 
early to late. It is extremely slow to bolt and makes fine clean hard 
heads even in the summer months. Earlier than Great Lakes, it is a 
sure-heading medium-sized type, with an attractive light green color 
and fine quality. 
Cornell 456 also does very well on upland and we highly recom- 
mend it for both home and commercial use. The heavily crumpled 
leaves form solid crisp heads even under adverse conditions, making 
it one of the easiest Iceberg types to grow. We are proud of our stock 
of this lettuce, for it is the true original type developed at Cornell 
University, and its performance is unsurpassed. 
Pkt. 15c; 44 Oz. 40c; Oz. 75c; 14 Lb. $2.10; 144 Lb. $3.25. 
525 IMPERIAL 44. Fine Quality Head Lettuce for Spring or Fall. 76 
days. This favorite “‘Iceberg’”’ type has tender, crumpled leaves, not as 
solid or as coarsely ribbed as the Great Lakes strains and is preferred by 
many people. It will not withstand as much summer heat but for early 
spring or fall crop it is still excellent, especially for home use. It is 
early and makes compact well-formed heads of medium to large size 
and slightly flattened shape. The tightly folded hearts blanch well and 
are most delicious. Uniform and a sure header, it is a valuable, high 
quality variety. 
Pkt. 10c; 44 Oz. 25c; Oz. 45c; 14 Lb. $1.25; 14 Lb. $1.80. 
82 days. This is now the favorite Iceberg lettuce all over the country and is still the best for most 
growers. It stands a long time without bolting and is so resistant to tip-burn that the heads remain 
in fine condition even in hot weather. 
The plants are large and vigorous, dark green in color and the fringed leaves wrap over very tightly 
making solid compact heads of unusual crispness. Great Lakes is an ideal summer lettuce for home 
gardeners and market growers alike, for it makes hard, clean heads under almost all conditions. They 
mature about a week after Pennlake. Be sure to give the plants plenty of room—thin to at least 14 
inches apart, and they will make the kind of heads that lettuce growers want. 
Pkt. 15c; 144 Oz. 40c; Oz. 75c; 14 Lb. $2.00; 14 Lb. $3.15. 
534 PREMIER GREAT LAKES. Large Early Heads. 81 days. This refined, uniform strain of Great 
Lakes is used by many upland growers. A little earlier but not as tip-burn resistant as Great Lakes, 
it has a smoother leaf and heads evenly. Selected by Prof. Lewis at Penn State College for earliness, 
uniformity and attractively fringed leaves with little blistering, it makes large well-rounded crisp 
heads of fine quality. Pkt. 15c; 144 Oz. 40c; Oz. 75c; 14 Lh. $2.00; 14 Lb. $3.15. 
542 WHITE BOSTON. sure Heading. 
68 days. The most popular “Butterhead’’ lettuce grown today. The leaves are light green and 
smoother and more tender than the crisp heading types, and they form excellent tightly folded heads 
of the most delicious quality and flavor. This variety heads well under all conditions and is resistant 
to tipburn, making it very valuable for large growers on both muck and upland. It is also the best 
butterhead type for home gardens. Our strain is exceptionally sure heading and uniform, every plant 
making a fine firm head. Pkt. 15c; Oz. 35c; 14 Lb. 85c; 14 Lb. $1.30. 
532 MIGNONETTE. Extra Early and Most Delicious. 65 days. For home use we prefer Mignonette 
to any other kind of head lettuce. It is very early and heads up exceptionally well. The heads are 
small, round and compact and the quality is the very finest—tender, crisp and without any bitter- 
ness. The outer leaves are dark green tinged with a distinctive reddish brown and the inside of the 
head is a beautiful creamy yellow. A splendid fine-flavored lettuce that every home gardener should 
try. Pkt. 15¢e; 4% Oz. 30c; Oz. 50c; 14 Lb. $1.35. 
COS OR ROMAINE LETTUCE 
540 TRIANON SELF FOLDING, The Best Cos Lettuce. 72 days. This upright compact lettuce is 
much prized for its fresh crispness and mild flavor. The firm heads are elongated, about 10 in. high, 
and the leaves grow closely together, blanching the heart perfectly white. The flavor is somewhat 
“sweeter’’ than most lettuce, and it is considered by many people the most delicious salad lettuce. 
Even the outer leaves are tender and palatable. Valuable for both home and market use, and per- 
forms very well on muck or upland. 
Pkt. 15¢; Oz. 35c; 14 Lb. 90c; 14 Lb. $1.35.
